Overview
E-LINK’s LNK-SFP-2.5G-20 Transceivers are a high performance, cost effective module
which have a duplex LC optics interface. They are compatible with the Small Form Factor
Pluggable Multi-Sourcing Agreement (MSA) and Digital diagnostics functions are available
via the 2-wire serial bus specified in SFF-8472. The receiver section uses a PIN receiver
and the transmitter uses a 1310 nm DFB laser, up to 13dB link budge ensure this module
