PRODUCT DESCRIPTION
1.25G SFP Transceiver products have been widely used in fields like network security, storage,server, telecommunication, finance, railway, military, oil, customs and water conservation, etc.
Transceivers are a high performance, cost effective module which have a single 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 FP laser, up to 14dB link budge ensure this module 1000Base-LX Ethernet 20km application.
The transmitter section uses a multiple quantum well laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.
