Embodiment Construction

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but 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 there is no conflict with each other.

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

[0032] The traditional PON service card only supports a single PON mode or a certain COMBO-PON mode, and cannot support multiple modes based on the port. The present invention proposes an implementation method for supporting a multi-mode PON system, and the port can be dynamically configured or adaptive to a variety of PONs It...

Abstract

The invention discloses a COMBO optical module. The COMBO optical module expands two PINs based on the 20 PIN SFP+ package size and adopts a 22 PIN SFP+ electrical interface. Based on the definition of data and control signals of the standard 20 PIN SFP+ optical module, the COMBO optical module is redefined. Data and control signals for the module. Based on the 20 PIN SFP+ package size expansion, two PINs adopt 22 PIN SFP+ electrical interface, specifically: add a PIN to the upper and lower layers of the standard 20 PIN SFP+ gold finger pin end, and maintain the structure and position of the rest of the standard 20 PIN SFP+ No change, the supporting optical module socket also adopts 22 PIN socket. The present invention also provides a multi-mode PON system including the above-mentioned optical module. The present invention can be used for GPON service or GPON smooth upgrade to 10GPON service without changing the ODN; the present invention can configure different ports into different modes according to actual user requirements, so that multi-mode PONs coexist.

Description

technical field [0001] The invention belongs to the technical field of passive optical network (Passive Optical Network, PON), and more particularly, relates to a COMBO optical module and a multi-mode PON system. Background technique [0002] With the mass 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 Passive Optical Network technology) have been unable to meet future broadband services. Development needs, the existing PON technology bandwidth will appear bottleneck. 10G GPON came into being, XG-PON (downstream 10G / upstream 2.5G) and XGS-PON (downstream 10G / upstream 10G) officially entered the application. [0003] During the evolution or upgrade of GPON to 10G GPON, there is an inevitable scenario where GPON and 10G GPON access coexist. Taking into account the full protection of the optical fiber resources depl...
