GLC-LH-SMD-SO SFP, 1G, 10km, Single Mode, 1310nm, with DOM

Transcription

1 General Description The 1G SFP optical transceivers are designed for Storage, IP network and LAN. It is a fully integrated 1 Gbps optical transceiver module. This module is designed for Single mode fiber and operates at a nominal wavelength of 1310nm. The transmitter section uses a multiple quantum well laser. The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header with a limiting post-amplifier IC. Product Features Operating data rate up to 1.25Gbps 1310nm transmitter 10km on SMF Single 3.3V power supply and TTL logic interface Duplex LC connector interface Hot pluggable Operating case temperature standard: 0 C to +70 C Compliant with MSA SFP specification Digital diagnostic monitor interface (also called DOM or DDM) Compatible with SFF
