Ethernet 1000BASE 20KM Fiber Optic SFP Module Bi-Directional SM 1310nm/1550nm
Applications
Fiber Channel
Switched backplane applications
Router/Server interface
Switch to Switch interface
Other optical transmission systems
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.
