Advantech SFP-GSM-40K Compatible Industrial 1.25Gbps SFP 1000BASE-LX40 1310nm 40km SMF Duplex LC DDM/DOM Optical Transceiver Module Advantech SFP-GSM-40K compatible optical transceiver is an industrial dual fiber 1000Mbps Small Form-factor Pluggable SFP module for use in 1000BASE Ethernet network. SFP LX40 provides 1Gb/s throughput up to 40km over single-mode fiber (SMF) using 1310nm wavelength. This transceiver is fully compliant with SFP Multi-Source Agreement (MSA), IEEE 802.3z 1000BASE-LX40 and SERDES standard. Its electrical interface is MSA compliant 20-pin edge type connector and the optical interface is Duplex LC connector. The full-duplex SFP transceiver features highly reliable DFB transmitter and PIN photo detector to offer high performance interconnection at 1.25Gbps data rate. Industrial modules extend the operating temperature range. Built-in Digital Diagnostic Monitoring/Digital Optical Monitoring (DDM/DOM) support is present for real-time performance monitoring via 2-wire (TWI/I2C) interface. Our modules are factory pre-programmed for compatibility, perform alternatively to genuine Advantech SFP-GSM-40K transceivers.
