Problems solved by technology

[0004] However, the optical module in the current 100G MSA protocol has only one 168PIN socket, and a group of 100G services based on OTL4.10 signals cannot be added, that is, it is impossible to realize the purpose of using an optical module form on line cards with different service rates at the same time
Taking 100G line card and 200G line card as an example, in the existing technology, a single socket with more pins can be used to realize 200G services, but it cannot be assembled on the 168PIN socket of the traditional 100G line card
It is also possible to use the traditional 100G line card with a higher-performance 100G optical module, which requires the use of a 200G signal processing chip to develop a 100G optical module using a 168PIN socket, but the cost of the 100G optical module in this way is high, and This approach to development is costly

Embodiment approach

[0083] In this embodiment, when the first male socket 11A of the 200G service rate optical module is plugged into the female socket of the traditional 100G service rate line card, since the traditional 100G service rate line card is only provided with one Therefore, the second male socket 11B does not form a signal connection with the line card of the 100G service rate, so the optical communication system can determine that the service mode is the 100G service mode.

[0084] In order to facilitate the understanding of the optical module, line card and optical communication system provided by the embodiment of the present invention, the following takes an optical module with a service rate of 200G as an example to analyze and explain the setting and working principle of the optical module:

[0085] Among them, the optical module of 200G service rate mentioned below is referred to as 200G optical module for short, the line card of 100G service rate is called 100G line card for sh...

Embodiments of the present invention include: more than two male sockets are provided, and the two or more male sockets are used for plugging with female sockets provided on a line card, and the line card includes lines of various service rates. card; the two or more male sockets include at least one first male socket, and the first male socket is configured according to the 100G service rate dense wavelength division multiplexing DWDM optical module multi-source protocol MSA.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an optical module, a line card and an optical communication system. Background technique [0002] With the rapid development of optical communication technology, communication operators have ushered in the era of 100G speed, 100G optical modules (optical transponders, Optical Transponder) have been standardized, and 100G long-distance dense wavelength division multiplexing (DWDM, Dense Wavelength Division Multiplexing) optical module multi-source agreement (MSA, Multi SourceAgreement), which stipulates that the physical bus interface of 100G optical module is a set of OTL4.10 (OTL: Optical channel Transport Lane, 4: OTU4 business, 10: 10 signal lines 100G optical module It can be connected with 100G line card, but due to the limitation of the number of 168PIN socket pins, it is impossible to add another set of OTL4.10 bus. [0003] At the same time, optical modules are al...
