Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0031] The technical problem to be solved in the present invention is:

[0032] Traditional PON service cards only support a single PON mode or a certain COMBO-PON mode, and cannot support multiple modes based on ports. This invention proposes an implementation method that supports multi-mode PON systems. Ports can be dynamically configured or self-adapted to multiple PONs mode, supporting the ...

Abstract

The invention discloses a COMBO optical module. The COMBO optical module expands the two PINs based on the 20 PIN SFP+ packaging size, adopts a 22 PIN SFP+ electrical interface, and redefines the dataand control signals of the COMBO optical module based on the data and control signal definition of the standard 20 PIN SFP+ optical module. Two PINs are expanded based on a 20 PIN SFP+ packaging size, and a 22 PIN SFP+ electrical interface is adopted. Specifically, a PIN is added to each of the upper layer and the lower layer of the spare part of the pin end of the standard 20 PIN SFP+ golden finger, the structure and the position of the other standard 20 PIN SFP+ are kept unchanged, and the matched optical module socket also adopts a 22 PIN socket. The invention also provides a multimode PONsystem comprising the optical module. The method can be used for GPON service or smooth upgrading of GPON to 10GPON service without changing the ODN, different ports can be configured into differentmodes according to actual user requirements, so that the multi-mode PON can coexist.

Description

technical field [0001] The present invention belongs to the technical field of Passive Optical Network (PON), and more specifically relates to a COMBO optical module and a multi-mode PON system. Background technique [0002] With the popularization of multimedia, high-definition video, and interactive games, EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) and GPON (Gigabit-Capable Passive Optical Networks, Gigabit-Capable Passive Optical Network technology) have been unable to meet future broadband services Due to the needs of development, the bandwidth of existing PON technology will be bottlenecked. 10G GPON came into being, and XG-PON (downlink 10G / uplink 2.5G) and XGS-PON (downlink 10G / uplink 10G) have officially entered the application. [0003] During the evolution or upgrade process from GPON to 10G GPON, there will inevitably be scenarios where GPON and 10G GPON access coexist. Considering the full protection of the optical fiber resources...
