Optical module, line card and optical communication system

Abstract

The embodiments of the present invention disclose an optical module, a line card and an optical communication system, which are used to realize an optical module form and be used on line cards with different service rates at the same time, thereby reducing development costs. 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...

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
