Hello, Marko.

A remote interlock connector is required when there is
potential human exposure to laser radiation, as might be
found in labs or industrial environments where the laser is
cutting something or marking a product (there may be other
applications).  In such an environment, there is a need to
have the operator's station remote from the laser and its
target.

The remote interlock connector is intended to allow the
operator's station to connect to the lasing system to
start/interrupt lasing.  Some stations might have a dead-man
switch/key switch combination that provides a contact
opening/closure on the cable connected to the remote
interlock connector.

The key lock feature is separate from the remote interlock
connector.  One can not be substituted for the other.

I have a hard time imagining the need for a remote interlock
connector on an optical networking product.  You should
double check the laser class definitions and other
requirements applicable to your system.  You will probably
be pleasantly surprised (relieved).

The beam stop requirements apply to your output.  You're
right about the input fiber, though, and there's not a lot
that can be done, other than to follow the guidelines in
IEC60825-2 and ANSI Z136.2, as well as complying with
IEC60825-1 and 21CFR.
