Abstract
Description
Technical Field
[0001] This application relates to the field of optical communication technology, and in particular to an optical module connector and an optical communication device. Background Technology
[0002] With the development of optical communication systems, gigabit-capable PON (GPON) and 10-gigabit-capable PON (XG PON) systems in passive optical networks (PON) can no longer meet the needs of future broadband service development. PON systems are evolving towards higher bandwidth, for example, towards 50-gigabit-capable PON (50G PON). As PON systems evolve towards higher bandwidth, optical communication systems need to support signal transmission both before and after the evolution.
[0003] In current optical module connectors, to support both pre-evolution and post-evolution signal transmission, the upper and lower inner walls of the gold finger slot are each equipped with two rows of pins to provide more signal interfaces. However, this results in an excessively deep gold finger slot when supporting a large number of signal interfaces is required. Utility Model Content
[0004] This application provides an optical module connector and an optical communication device, which offer more signal interfaces through multiple gold finger slots, thereby reducing the depth of the gold finger slots. The technical solution adopted is as follows:
[0005] In a first aspect, this application provides an optical module connector, which includes a plurality of gold finger slots; the plurality of gold finger slots are stacked and arranged along a target direction, wherein the target direction is the width direction or the thickness direction of the gold finger slot; adjacent gold finger slots among the plurality of gold finger slots are arranged one after the other in the insertion direction of the gold finger slot.
[0006] In the solution shown in this application, the optical module connector provides multiple gold finger slots stacked along the target direction. Compared to adding pins in the insertion direction of the gold finger slots, the depth of the gold finger slots can be reduced while providing more signal interfaces. Furthermore, it provides the possibility of different gold finger insertions, thus supporting both evolved and un-evolved gold finger insertions during the evolution process. Moreover, the adjacent gold finger slots are arranged one after the other in this insertion direction, minimizing the impact between adjacent gold finger slots and reducing the height of the optical module connector even with multiple gold finger slots.
[0007] In one alternative approach, the plurality of gold finger slots include slots for inserting gold fingers of different modes, each corresponding to a different transmission rate, and the optical module connector is capable of accepting gold fingers of different modes.
[0008] Alternatively, among the multiple gold finger slots, there are slots for inserting gold fingers of the same pattern, with the same pattern corresponding to the same transmission rate, and the optical module connector can accommodate gold fingers of the same pattern.
[0009] In one alternative approach, when the optical module connector supports 50G PON tri-mode communication, the multiple gold finger slots include a first gold finger slot and a second gold finger slot. The first gold finger slot is for inserting the first gold finger of 50G PON, and the second gold finger slot is for inserting the second gold finger of 10G PON and GPON. Thus, when the first and second gold fingers belong to the same optical module, the optical module connector supports 50G PON tri-mode optical modules; when the first and second gold fingers belong to different optical modules, the optical module connector supports insertion of optical modules before the 50G PON evolution and also supports insertion of 50G PON optical modules after the evolution, providing greater flexibility.
[0010] In one alternative approach, when the target direction is the thickness direction of the gold finger slot, the first gold finger slot is located above the second gold finger slot, and the first gold finger slot is arranged after the second gold finger slot along the insertion direction. This makes it easier to add a high-speed gold finger slot above the existing low-speed gold finger slot without requiring repositioning.
[0011] In one alternative embodiment, each of the plurality of gold finger slots includes a first inner wall and a second inner wall, which are opposite each other along the thickness direction of the gold finger slot. One or more sets of pins are disposed on the first inner wall of each gold finger slot, and one or more sets of pins are disposed on the second inner wall of each gold finger slot. This arrangement of pins on the inner walls opposite each other along the thickness direction makes it easier for the gold fingers of the optical module to connect to them.
[0012] In one alternative approach, the first inner wall and the second inner wall have the same number of pin groups. This simplifies the design.
[0013] In one alternative approach, each gold finger slot has multiple sets of pins, each containing the same number of pins. This simplifies the design.
[0014] In one alternative approach, the multiple gold finger slots are arranged sequentially from front to back along the insertion direction, so that the multiple optical modules have less mutual influence when inserted, making it convenient for the optical modules to be inserted.
[0015] In one alternative approach, when the target direction is the thickness direction of the gold finger slot, the end of the optical module connector away from the gold finger slot is flat for ease of manufacturing. Alternatively, when the target direction is the thickness direction, the junction between the end of the optical module connector away from the gold finger slot and the top of the optical module connector is beveled, which facilitates the assembly of the optical module connector into the corresponding optical communication equipment.
[0016] Secondly, this application provides an optical communication device, the optical communication device including a single board and an optical module connector as described in the first aspect or any optional method of the first aspect, the single board being electrically connected to pins in the plurality of gold finger slots.

[0029] 1. Gold finger slot; 11. Pins; 2. Board. Detailed Implementation
[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0031] In optical access networks, PON systems have continuously evolved in recent years, from 10G PON to 50G PON. To ensure compatibility with existing GPON and 10G PON optical communication equipment, the 50G PON optical line terminal (OLT) supports three modes: GPON ONU, 10G PON ONU, and 50G PON ONU support optical communication. The ONU is equivalent to the optical network terminal (ONT). This OLT is also known as the 50G PON tri-mode OLT. The OLT and ONU are connected via an optical distribution network (ODN). See [link to relevant documentation]. Figure 1 .
[0032] Optical communication equipment communicates via optical modules. At different stages of evolution, different packaged optical modules are required. For example, GPON uses 20-pin small form-factor pluggable (SFP) optical modules, while 10G PON uses 22-pin small form-factor pluggable plus (SFP+) optical modules. As the number of optical ports on a single circuit board increases, SFP-like packaged optical modules are gradually gaining acceptance, such as small form factor pluggable double density (SFP-DD) optical modules or next-generation small form factor pluggable double density (NGSFP-DD) optical modules. When using optical modules with different packages, compatible optical module connectors are required.
[0033] In one design, the optical module uses an SFP-DD optical module with 40 pins on its gold fingers, arranged in two rows. Two rows of pins are located on the upper surface of the gold fingers, and the other two rows are located on the lower surface. In this design, the upper inner wall of the gold finger slot has two rows of pins, and the lower inner wall has two rows of pins, with each row containing 10 pins. This means the optical module connector can only accept SFP-DD optical modules and is incompatible with other optical modules (such as 22-pin 10G combo optical modules), resulting in poor flexibility. Furthermore, supporting flexible insertion of other optical modules is limited by the number of internal components in a 50G PON tri-mode optical module, leading to higher costs. In another design, the optical module connector includes two gold finger slots with flush insertion ends. When the gold fingers of the optical module are inserted, the gold finger slots are stretched open in the thickness direction. Therefore, to prevent interference between the two gold finger slots, the distance between them must be larger, resulting in a thicker optical module connector.
[0034] Based on this, this application provides an optical module connector including multiple gold finger slots 1, which are stacked along a target direction, namely the width or thickness direction of the gold finger slots 1. Adjacent gold finger slots 1 are arranged one behind the other in an insertion direction, which is the direction in which the multiple gold finger slots 1 are inserted into the optical module. Thus, compared to the optical module connector corresponding to an SFP-DD optical module, this application provides an optical module connector with multiple gold finger slots 1. This allows for more signal interfaces while reducing the depth of the gold finger slots, reducing layout pressure, and enabling the insertion of different optical modules into a single optical module connector. Different gold finger slots 1 can insert different optical modules, or multiple gold finger slots 1 can insert a single optical module, offering greater flexibility. Furthermore, compared to an optical module connector where the insertion ends (also called plug-in ends) of two gold finger slots 1 are flush, the possibility of mutual interference is smaller because the insertion ends of adjacent gold finger slots 1 along the target direction are not flush. Therefore, the thickness of the optical module connector can be reduced. Furthermore, it eliminates the need for high-cost chips, enabling the use of optical modules in multiple modes, thereby reducing the cost of optical module connectors.
[0035] This optical module connector, also known as a connector, can be used in the OLT or ONU of the PON system mentioned earlier, and can also be used in other application scenarios that require the insertion of optical modules. For example, optical communication equipment in an optical transport network includes an optical module connector for inserting optical modules.
[0036] Figure 2 A schematic diagram of the first structure of an optical module connector is provided. (See diagram below.) Figure 2 As shown, the optical module connector includes multiple gold finger slots 1, with the number of gold finger slots 1 being greater than or equal to 2. These multiple gold finger slots 1 are stacked and arranged along a target direction, which is either the thickness direction or the width direction of the gold finger slot 1. The thickness direction is the height direction of the optical module connector, and the width direction is the width direction of the optical module connector. The thickness direction is perpendicular to the width direction and also perpendicular to the insertion direction of the gold finger slot 1, which is the direction in which the gold finger slot 1 is inserted into the optical module. Adjacent gold finger slots 1 are arranged front-to-back along this insertion direction, which is equivalent to a staggered arrangement of adjacent gold finger slots 1 in the insertion direction. Figure 2 The diagram shows an example of an optical module connector including three gold finger slots 1.
[0037] Figure 3 A second structural diagram of the optical module connector is provided. (See diagram below.) Figure 3As shown, the multiple gold finger slots 1 are arranged back-to-back along the insertion direction, which is the direction in which the gold finger slots 1 are inserted into the optical module. The insertion ends of every two sets of adjacent gold finger slots 1 are either the same or different in the insertion direction. This type of optical module connector, because its multiple gold finger insertion ends 1 are stepped, can be called a stepped optical module connector.
[0038] Optionally, in the optical module connector, the thickness and depth of the multiple gold finger slots 1 are set according to actual needs. In one embodiment, the thickness and / or depth of the multiple gold finger slots 1 in the optical module connector are all the same.
[0039] Optionally, in the optical module connector, the top surface of the insertion end of the plurality of gold finger slots 1 is made into a bevel in the thickness direction to facilitate the insertion of the optical module.
[0040] In one alternative approach, multiple gold finger slots 1 have slots for inserting gold fingers of different modes. For example, the multiple gold finger slots 1 include three gold finger slots 1, which respectively insert gold fingers for 50G PON, 10G PON and GPON.
[0041] Alternatively, multiple gold finger slots 1 may contain slots for inserting gold fingers of the same pattern. For example, the multiple gold finger slots 1 may include three gold finger slots 1, where the first and second gold finger slots 1 are for inserting 50GPON gold fingers, and the third gold finger slot 1 is for inserting 10G PON and GPON gold fingers, which belong to a combo optical module.
[0042] The mode corresponds to the transmission rate; the same mode corresponds to the same transmission rate, while different modes correspond to different transmission rates. For example, the transmission rate corresponding to 50G PON mode is different from that corresponding to 10G PON mode.
[0043] In one optional embodiment, the multiple gold finger slots 1 include two gold finger slots 1, each comprising a first gold finger slot and a second gold finger slot. The first gold finger slot is for inserting a first gold finger, which is a 50G PON gold finger. The second gold finger slot is for inserting a second gold finger, which is a gold finger shared by 10G PON and GPON. The first and second gold fingers can belong to the same optical module or different optical modules. When belonging to the same optical module, it allows for the insertion of a 50G PON tri-mode optical module. When belonging to different optical modules, it ensures compatibility with optical modules evolved to 50G PON. This allows for the flexible use of optical modules with transmission rates of 10Gbps and below while enabling the sharing of three 50G PON modes.
[0044] Optionally, the positional relationship between the first gold finger slot and the second gold finger slot can be set according to actual needs, and this application embodiment does not limit it. In one solution, such as Figure 4 As shown, when the target direction is the thickness direction of the gold finger slot 1, since the second gold finger slot existed before the 50G PON evolution, for ease of layout, the first gold finger slot is generally located above the second gold finger slot, and along the insertion direction, the first gold finger slot is arranged after the second gold finger slot. In another scheme, when the target direction is the thickness direction of the gold finger slot 1, the second gold finger is located above the first gold finger.
[0045] Optionally, corresponding Figure 4 The optical module connector shown in the embodiment of this application also provides a perspective view of the optical module connector, see below. Figure 5 .exist Figure 5 In the middle, the outer sides of the insertion ends of the first and second gold finger slots are both made into bevels, which facilitates the insertion of the optical module.
[0046] Optionally, Figure 4 The optical module connector shown can be flexibly inserted into both pre-evolution optical modules and post-evolution optical modules. See also Figure 6 In (a), the optical module connector can be used to insert 10G PON and GPON optical modules, which include 10G PON and GPON gold fingers, and is a combo optical module. See also Figure 6 (b) In this context, the optical module connector can be used to insert a 50GPON optical module, which includes 50G PON gold fingers. See also... Figure 6(c) In this context, the optical module connector can be used to insert a tri-mode optical module of 50G PON, 10GPON and GPON, which includes gold fingers for 50GPON, 10GPON and GPON.
[0047] Along the insertion direction, the distance between the insertion ends of the first gold finger slot and the second gold finger slot can be set according to actual needs, so as to keep the thickness of the optical module connector low and the length in the insertion direction not too long.
[0048] In one alternative embodiment, to enable the gold fingers to connect to the circuit board of the optical communication equipment to which the optical module connector belongs after being inserted into the gold finger slot 1, each of the multiple gold finger slots 1 includes a first inner wall and a second inner wall, which are opposite each other along the thickness direction. Each gold finger slot 1 has one or more sets of pins 11 arranged along the insertion direction of the gold finger slot 1 on the first inner wall, and each gold finger slot 1 also has one or more sets of pins 11 arranged along the insertion direction of the gold finger slot 1 on the second inner wall. The pins 11 can be referred to as leads. Each pin 11 is electrically connected to the circuit board of the optical communication equipment to which the optical module connector belongs; this electrical connection can be achieved through wires or other means.
[0049] Optionally, each pin 11 can be a pin for transmitting independent signals or a pin for transmitting multiplexed signals.
[0050] Optionally, the number of pin groups 11 provided on the first inner wall and the second inner wall can be set according to actual needs. In one embodiment, the number of pin groups 11 provided on the first inner wall and the second inner wall is the same. For example, in the case of a 50G PON tri-mode optical module connector, one group of pins 11 is provided on both the first inner wall and the second inner wall.
[0051] In the case where a set of pins is provided on both the first inner wall and the second inner wall, there is no front and rear pin configuration. Therefore, there is no need to worry about the possibility of the single-board chip being damaged due to inconsistent front and rear pin definitions, and the configuration method is relatively simple.
[0052] When multiple sets of pins are arranged on the first and / or second inner walls, with the pins 11 arranged along the insertion direction, the gold finger will first contact the set of pins closest to the insertion end during insertion, and then insert further. Thus, during insertion, the first pin 11 contacted may be a low-level signal, while the later pin 11 contacted may be a high-level signal, increasing the current. This could potentially damage the single-board chip, which is a media access control (MAC) chip, due to excessive current. Therefore, we can define the front and rear pins as consistently as possible to reduce the possibility of chip damage. Alternatively, even if the front and rear pin definitions are inconsistent, we can protect the single-board chip to prevent damage.
[0053] Optionally, in multiple gold finger slots 1, the number of pin groups 11 set in different gold finger slots 1 can be the same or different. For example, see Figure 7 In (a), the plurality of gold finger slots 1 include two gold finger slots 1, one gold finger slot 1 having a set of pins 11, and the other gold finger slot 1 having a set of pins 11. See also, for example, […]. Figure 7 In (b), the plurality of gold finger slots 1 includes two gold finger slots 1, one gold finger slot 1 having four sets of pins 11, and the other gold finger slot 1 having four sets of pins 11. For example, see [link to example]. Figure 8 In (a) and (b), the plurality of gold finger slots 1 include two gold finger slots 1, one gold finger slot 1 is provided with 4 sets of pins 11, and the other gold finger slot 1 is provided with 2 sets of pins 11.
[0054] Optionally, the multiple sets of pins 11 provided in each gold finger slot 1 include the same number of pins. For example, in the case of a 50G PON tri-mode optical module connector, one set of pins 11 is provided on both the first inner wall and the second inner wall of the first gold finger slot, and one set of pins 11 is provided on both the first inner wall and the second inner wall of the second gold finger slot. In this way, the optical module connector includes 4 sets of pins 11, and each set of pins 11 includes 11 pins 11.
[0055] In one implementation, along the insertion direction, the first inner wall of the second gold finger slot is located below the second inner wall. The 11 pins on the first inner wall are pins 1 to 11 from left to right. Pin 1 is the positive signal transmission pin of GPON, pin 2 is the negative signal transmission pin of GPON, pin 3 is the ground pin, pin 4 is the transmitter shutdown control pin, pin 5 is the two-wire serial bus (inter-integrated circuit, I2C) data signal pin, pin 6 is the I2C clock signal pin, pin 7 is the negative signal reception pin of GPON, pin 8 is the reset pin of XG PON, pin 9 is the signal check pin of XG PON, pin 10 is the received signal strength detection request pin, and pin 11 is the positive signal reception pin of GPON. The 11 pins on the second inner wall, from right to left, are pins 12 to 22. Pin 12 is the XG PON transmission rate selection pin, used to select the uplink transmission rate as 10Gbps, 2.5Gbps, or no pin. Pin 13 is the receive ground pin. Pin 14 is the XGPON negative signal receive pin. Pin 15 is the XG PON positive signal receive pin. Pin 16 is the GPON signal check pin. Pin 17 is the receive power supply pin. Pin 18 is the transmit power supply pin. Pin 19 is the GPON reset pin. Pin 20 is the XG PON positive signal transmit pin. Pin 21 is the XG PON negative signal transmit pin. Pin 22 is the transmit ground pin.
[0056] In the case of an XG PON as a symmetrical passive optical network, the uplink and downlink transmission rates are both 10Gbps, with a compatible uplink transmission rate of 2.5Gbps. Pin 12 is the rate selection pin, used to select whether the uplink transmission rate is 2.5Gbps or 10Gbps. The two uplink transmission rates operate in a time-division multiplexing manner. In the case of a symmetrical passive optical network, this is represented as a 10-Gigabit symmetric passive optical network (10-Gigabit symmetric PON, XGS PON). In the case of an asymmetrical passive optical network, the uplink transmission rate is 2.5Gbps, and the downlink transmission rate is 10Gbps. Pin 12 is an unconnected pin, also known as an undefined pin. Figure 1 In the optical communication system shown, uplink transmission refers to transmission from ONU to OLT, and downlink transmission refers to transmission from OLT to ONU.
[0057] For the first gold finger slot, its two sets of pins can be configured according to actual needs to support communication with the gold fingers of the 50G PON optical module.
[0058] In another implementation, pin 11 of the first gold finger slot and pin 11 of the second gold finger slot are defined in a unified manner so that the first gold finger slot and the second gold finger slot support the insertion of a 50G PON tri-mode optical module.
[0059] Optionally, the multiple sets of pins 11 provided by the multiple gold finger slots 1 may include the same or different numbers of pins.
[0060] Optionally, multiple pins 11 in each group of pins 11 are flush at one end along the insertion direction. Specifically, whether the ends closer to the insertion end or the ends farther from the insertion end are flush depends on the pin distribution of the inserted gold fingers. In this way, each group of pins 11 can also be referred to as each row of pins 11.
[0061] In one alternative embodiment, when the target direction is the thickness direction of the gold finger slot 1, the end of the optical module connector furthest from the gold finger slot 1 is flat, see [reference needed]. Figure 8 (a) and (b) in the example.
[0062] Alternatively, if the target direction is the thickness direction of the gold finger slot 1, the end of the optical module connector away from the gold finger slot 1 has a flat surface, and the top of the optical module connector is also flat. The junction between this end and the top of the optical module connector is beveled. See [reference needed]. Figure 6 (a), (b), and (c) are shown in the diagram. This design allows one corner of the optical module connector to be beveled, facilitating its integration into optical communication equipment.
[0063] In one alternative approach, based on the principles of this application, the optical module connector has several possible structures, see [link to relevant documentation]. Figure 9 The third structural diagram and Figure 10 The fourth structural diagram is shown in the image. Figure 9 In the optical module connector, the insertion ends of the multiple gold finger slots 1 are stepped, and the ends away from the insertion ends are also stepped. Figure 10 In the optical module connector, the insertion ends of the multiple gold finger slots 1 are stepped, and the ends away from the insertion ends are flat. When the multiple gold finger slots 1 are stacked along the thickness direction of the gold finger slots 1, the first distance is smaller than the second distance. The first distance is the distance between the insertion end of the lower gold finger slot 1 and the end away from the insertion end, and the second distance is the distance between the insertion end of the upper gold finger slot 1 and the end away from the insertion end.
[0064] In an alternative embodiment, the optical module connector is also provided with an optical cage for limiting the position of the inserted optical module.
[0065] The optical module connector provided in this application embodiment can be used to insert SFP-type optical modules, or to insert similar quad small form-factor pluggable (QSFP), 10 gigabit small form-factor pluggable (XFP), or 12-way 10 gigabit pluggable (CFP) optical modules.
[0066] This application also provides an optical communication device, which includes a single board 2 and any of the optical module connectors in this application embodiment. The number of optical module connectors can be one or more. When there are multiple optical module connectors, multiple optical modules can be inserted, achieving high-density connection between the single board and multiple optical modules. Figure 11 As shown, for each optical module connector, multiple gold finger slots 1 of the optical module connector are electrically connected to the single board 2, such as pins 11 in each gold finger slot 1 being electrically connected to the single board 2.
[0067] The optical communication device can be any device that requires the insertion of optical modules, such as an OLT or an ONU. The OLT includes 16 optical module connectors.
