Product Description

Approved Optics LS-SFP-SX-A is a multi-mode transceiver - a small form factor
pluggable module for bi-directional serial optical data communications such as Gigabit
Ethernet 1000BASE-SX and Fiber Channel SM-LC-L FC-Pl. This module is designed
for multi-mode fiber and operates at a nominal wavelength of 850nm.

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 GaAs detector preamplifier (IDP) mounted in an optical header and a
limiting post-amplifier IC.

The LS-SFP-SX-A is designed to be compliant with SFF-8472 SFP Multi-source
Agreement (MSA).
