Generic SFP-FE-BX20U-3155-I Compatible Industrial 125Mbps BIDI SFP 100BASE-BX20 TX1310nm/RX1550nm 20km SMF Simplex LC DDM/DOM Optical Transceiver Module Dawnray’s SFP-FE-BX20U-3155-I optical transceiver is an industrial single fiber bidirection 125Mbps Small Form-factor Pluggable SFP BIDI module for use in 100BASE Ethernet network. SFP BX20U-3155 provides 125Mb/s throughput up to 20km over single-mode fiber (SMF) using 1310nm in transmitter side and 1550nm in receiver side. This transceiver is fully compliant with SFP Multi-Source Agreement (MSA), IEEE 802.3 100BASE-BX20 and SERDES standard. Its electrical interface is MSA compliant 20-pin edge type connector and the optical interface is Simplex LC connector. The full-duplex SFP transceiver features highly reliable FP transmitter and PIN photo detector to offer high performance interconnection at 125Mbps 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 generic/MSA transceivers.
