DESCRIPTION
The SPS-7120WG series single mode transceivers is small
form factor pluggable module for bi-directional serial
optical data communications such as Gigabit Ethernet
1000BASE and Fibre Channel 1x SM-LC-L FC-PI. It is
with the SFP 20-pin connector to allow hot plug capability.
Digital diagnostic functions are available via an I
2
C. This
module is designed for single mode fiber and operates at a
nominal wavelength of 1310 nm. 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.
LASER SAFETY
This single mode transceiver is a Class 1 laser product. It
complies with IEC-60825 and FDA 21 CFR 1040.10 and
1040.11. The transceiver must be operated within the
specified temperature and voltage limits. The optical ports
of the module shall be terminated with an optical connector
or with a dust plug.
