1000BASE-LX SFP Module TX1490nm RX1550nm 60KM BIDI SFP SM For Fiber Channel
PRODUCT DESCRIPTION
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 1490 nm DFB laser, up to 14dB link budge ensure this module 1000Base-LX Ethernet 60km application.
1.25Gbps SFP BIDI 60KM Optical Transceiver Module Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the DFP laser and the PIN photo-detector .
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.
