25G SFP28 LR Lite 300m
25GBASE-LR-S SFP28 1310nm 300m Duplex LC SMF DDM Optical Transceiver, DFB+PIN
Description
25GBASE-LR-S SFP28 1310nm 300m Transceiver Module
The Arkoptics' AF-SP25G-3H is a 310nm DFB laser based 25Gb/s SFP28 transceiver. It converts 25Gbit/s serial PECL or CML electrical data into serial optical data. The DFB transmitter and PIN receiver provide superior performance for Ethernet applications at up to 300m links over single mode fiber.
This 25GBASE-LR-S transceiver module is compliant with SFF-8472, SFF-8402, SFF-8432and applicable portions of SFF-843. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472. The fully SFP28 compliant form factor provides hot pluggability, easy optical port upgrades and low EMI emission.
