Description
The S2036 is designed specifically to
implement the Fibre Channel Open Fiber
Control (OFC) system, a redundant
safety interlock feature for laser-based
fiber optic systems. It is functionally
compliant with the ANSI XT311 Fibre
Channel
physical
implements the OFC system defined by
that standard, to detect when the optical
link has been disrupted and shut down
the laser or reduce the optical power
level. The S2036 employs effectively
redundant paths, each of which can
independently turn off the laser.

Overview
The OFC system is an open fiber link
detection and laser control system speci-
fied in ANSI XT311 Fibre Channel
physical standard. It is used as a safety
interlock for point-to-point optical fiber
links that use semiconductor laser
diodes as the optical source. The major
reason for implementing OFC is that the
optical power levels required to obtain
the desired level of system performance
in Fibre Channel exceeds the Class 1
limits defined by national and interna-
tional laser safety standards, if the
optical fiber link between two optical
ports is disconnected, such as would
occur with an opened connector or a cut
fiber. It is extremely important that
requirements for Class 1 classification
are met, due to the potential for cus-
tomer exposure to laser radiation.
Since it is only when an optical link is
opened that a user can be exposed to
laser radiation, implementing OFC
allows Class 1 classification require-
ments to be met, since it can detect
when the link has been disrupted and
can shut down the laser or reduce the
optical power level. The S2036 complies
fully with the OFC specifications and
Class 1 requirements.
Refer to the ANSI Fibre Channel stan-
dard document for details of OFC
operation.
