Abstract

The invention discloses an EPON OLT (Ethernet Passive Optical Network Optical Line Terminal) optical module, in particular to a dual-channel GEPON OLT CSFP (Gigabitcapable Passive Optical Network Optical Line Terminal Compact Small Form Factor Pluggable) optical module, which comprises a power supply soft starting circuit, a microcontroller, an I channel laser drive circuit, an I channel amplitude limit amplification circuit, an I channel avalanche photodiode boosted circuit, an I channel RSSI (Received Signal Strength Indicator) image current source and a sampling maintaining circuit, two I channel optical receiving and sending assemblies, a 20-pin CSFP gold finger connector and an I channel LC interface. Due to the I channel optical receiving and sending assemblies, the optical module can work in a one-path and one-channel standard SFPEPONOLT mode which is compatible with the traditional EPON system, and can also work in a dual-channel CSFPEPONOLT mode with doubled port density and data throughput, thus a system is favorably maintained in smooth transition and upgrading, and system upgrading cost and equipment input cost of an operator are effectively reduced.

Description

technical field [0001] The invention relates to an optical line terminal (GEPON OLT) technology of a Gigabit Ethernet passive optical network, in particular to an optical module adopting CSFP packaging and integrating a dual-channel dual-channel GEPON OLT. Background technique [0002] As a mainstream technology for fixed access, Gigabit Ethernet passive optical network has mature solutions and stable performance, and is gradually realizing a large number of commercial applications. The SFP single-fiber dual-port transceiver optical module is a small hot-swappable optical module that conforms to the MSA protocol. It provides the function of bidirectional data transmission in the optical communication system. The SFP single-fiber dual-port optical module has the characteristics of high transmission rate and small size. The traditional SFP single-fiber dual-port EPON OLT optical module includes a microcontroller, an APD boost circuit, a mirror current source and a sample-and-h...
