Abstract

The invention discloses a device for realizing combined and shunted transmission of an optical signal relay. The device comprises a downlink link unit and an uplink link unit, wherein the downlink link unit is used for performing optical / electric conversion and compensation on a received composite optical signal, and outputting composite optical signals which are divided into at most 8 identical paths after electric / optical conversion; and the uplink link unit is used for performing optical / electric conversion on the received at most 8 paths of composite optical signals respectively, combining the converted at most 8 paths of electric signals, and outputting the combined electric signals after electric / optical conversion. The device realizes solution for relay in the optical signal transmission and provides multiple ports for a plurality of backward stage equipment access application in a system.

Description

Device for realizing optical signal relay and branch transmission technical field The invention relates to the technical field of mobile communication access network, in particular to a device for realizing optical signal relay and branch transmission. Background technique In the current optical transmission network, the relay compensation of optical signals is realized through erbium-doped optical amplifiers, etc., and the cost is very high, which is not conducive to being used in short-distance resident access networks. Moreover, many existing access transmission methods are not applicable due to different standards, or the narrow frequency bands cannot implement multi-network integration, and broadband transmission cannot independently build a unified resident access network that can implement multi-source access, such as : EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) and GE-PON (GHz Ethernet Passive Optical Network, Gigabit Ethernet Pass...
