Arista Networks SFP28-25G-DL-38.19 Compatible 25GBASE-DWDM SFP28 100GHz C49 1538.19nm 10km SMF LC DOM Optical Transceiver Module

Arista Networks SFP28-25G-DL-38.19 compatible optical transceiver is a dual fiber 25.8Gbps Small Form-factor Pluggable SFP28 DWDM module for use in 25GBASE Ethernet. SFP28 DWDM3819-LR provides 25Gb/s throughput up to 10km over single-mode fiber (SMF) with host FEC using C49 1538.19nm wavelength. This transceiver is fully compliant with SFP28 Multi-Source Agreement (MSA), IEEE 802.3 25GBASE-DWDM and 25GAUI standard. Its electrical interface is MSA compliant 20-pin edge type connector and the optical interface is Duplex LC connector. The full-duplex SFP28 transceiver features highly reliable DWDM EML transmitter and PIN photo detector to offer high performance interconnection at 25 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 SFP28-25G-DL-38.19 transceivers.
