Cleaning the Optical Interface
A protective connector plug is supplied with each
module. This plug should remain in place prior to
use, and be re-attached whenever a ber cable is not
inserted.
This will keep the optical interface free
from
dust
or
other
contaminants,
which
may
potentially degrade the optical signal. Before re-
attaching the connector plug to the module, visually
inspect the plug and remove any contamination. If
the optical interface becomes contaminated, it can
be cleaned with high-pressure nitrogen. Liquids or
physical contact with the optical interface are not
advised due to potential damage.
Assembly on Printed Circuit Board
The module can be soldered by hand or by a reow
process.
For hand soldering, a soldering iron with its tip
connected to ground should be used. Solder
extractors, including replacement parts, should
be of the non-static generating type.
For reow soldering, the recommendations
advised by Zarlink in the technical note
“MFTN6005A Manufacturing Guidelines” should
be followed. This document provides guidelines
about choice of solder, reow temperature and
time prole etc.
Use of solder with no-clean ux, i.e. solder that does
not
require
washing
after
assembly,
is
recommended. Washing the module with any kind of
liquid is not advised due to potential damage.
Eye Safety
This
module
includes
Vertical
Cavity
Surface-
Emitting Lasers (VCSELs) and is designed for
inherent eye safety without the need for loopback
control. An activity detector monitors the data input
on each of the electrical input channels of the
transmitter. If there are no data transitions on a
channel within a certain time, the channel’s laser will
be automatically turned off. This prevents potential
non eye-safe conditions caused by the laser being
stuck in the “on” state. The channel will resume
normal operation automatically once activity is again
detected.
The maximum optical power is certied to comply to
Class 1M in accordance with IEC 60825-1/A2:2001
and IEC 60825-2:2000.
Electrostatic Discharge (ESD)
The module is classied as Class 1 according to
MIL-STD-883, test method 3015. When handling the
modules, precautions for ESD sensitive devices
should be taken. These precautions include use of
ESD
protected
work
areas
with
wrist
straps,
controlled
work
benches,
oors
etc.
The
recommendations advised by Zarlink in the technical
note "MFTN6005A Manufacturing Guidelines" should
be followed.
