Overview - Cisco Compatible 1000Base-LX SFP Transceiver (GLC-LH-SM)

This hot pluggable Cisco compatible small form factor optical transceiver is designed for single-mode fiber (SMF) and operates at a nominal wavelength of 1310 nm. It provides standard AC coupled CML for high speed signals and LVTTL control and monitoring of signals. This optical transceiver consists of two sections: the transmitter uses a 1310 nm Fabry-Perot (FP) laser; the receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. In addition, the transceiver is compliant with SFP Multi-Source Agreement (MSA) specification and SFF-8472.
