Product Description
Approved Optics’ E1MG-LX-A is a single-mode transceiver - a small form factor
pluggable module for bi-directional serial optical data communications such as Gigabit
Ethernet 1000BASE-LX and Fiber Channel 1x SM-LX-L FC-Pl. 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 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 E1MG-LX-A is designed to be compliant with SFF-8272 SFP Multi-source
Agreement (MSA).
