Arista Networks SFP-1G-CW-1490 Compatible 1000BASE-CWDM SFP 1490nm 40km SMF LC DOM Optical Transceiver Module


Arista Networks SFP-1G-CW-1490 compatible optical transceiver is a dual fiber 1000Mbps Small Form-factor Pluggable SFP CWDM module for use in 1000BASE Ethernet. SFP CWDM1490-EX provides 1Gb/s throughput up to 40km over single-mode fiber (SMF) using 1490nm wavelength. This transceiver is fully compliant with SFP Multi-Source Agreement (MSA), IEEE 802.3 1000BASE-CWDM 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 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 Arista Networks SFP-1G-CW-1490 transceivers.
