Abstract

The invention discloses a CSFP optical module integrating dual-channel GPON OLT, which includes a CSFP gold finger and a microcontroller, and also includes a one-channel working circuit and a two-channel working circuit. The present invention integrates two GPON OLT working circuits that work independently of each other into one CSFP package, realizes two-way transmission and reception of two channels in one CSFP package, greatly reduces the external dimensions of optical modules and optical system equipment, and increases communication ports Density and data throughput, reducing network equipment costs.

Description

technical field [0001] The invention relates to the field of gigabit passive optical network optical line terminal (GPON OLT), in particular to a CSFP optical module integrating dual-channel GPON OLT. Background technique [0002] GPON (Gigabit-Capable PON) technology is the latest generation broadband passive optical integrated access standard based on the ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. Most operators regard it as an ideal technology to achieve broadband and comprehensive transformation of access network services. The existing standard SFP optical transceiver module using GPON technology uses a single bidirectional transceiver device to receive and send data, the communication port density and data throughput are small, and the cost of network equipment is high. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of low com...
