Dell SFP-GE-BX120U-1490 Compatible 1000BASE-BX BIDI SFP TX1490nm/RX1550nm 120km SMF LC DOM Optical Transceiver Module
Dell SFP-GE-BX120U-1490 compatible optical transceiver is a single fiber bidirection 1000Mbps Small Form-factor Pluggable SFP BIDI module for use in 1000BASE Ethernet. SFP BX120U provides 1Gb/s throughput up to 120km over single-mode fiber (SMF) using 1490nm in transmitter side and 1550nm in receiver side. This transceiver is fully compliant with SFP Multi-Source Agreement (MSA), IEEE 802.3 1000BASE-BX120 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 DFB transmitter and APD photo detector to offer high performance interconnection at 1 Gbps data rate. Built-in Digital Diagnostic Monitoring (DDM) support is present for real-time performance monitoring via 2-wire Interface (TWI/I2C). Our modules are factory pre-programmed for compatibility, perform identically to original Dell SFP-GE-BX120U-1490 transceivers.
