Safety Notes on Laser Singlemode type Connectors
The FMC-SA uses 1300 nm wavelength, eye-safe type laser, fiber optic single
mode connectors .
When connecting pairs of devices using laser type connectors or connecting
pairs of devices using LED type connectors, simply plug in the fiber optic
connectors in the normal manner. However, if mixed LED and eye-safe laser
driven devices are connected, the laser emitter has the potential (may in some
installations) to saturate the Rx (Receive) port on the LED driven device. In
effect, the LED port might be “dazzled” by the intensity of the laser source.
Net Optics’ recommends that an attenuator providing a (4-7db reduction) be
inserted in the F/O cable segment between the two units to reduce the light
intensity propagating from the eye-safe laser driven device. The attenuator
only needs to be inserted on the fiber optic cable strand linking the Tx
(Transmit) port on the laser driven device, and the Rx (Receive) port on the
Net Optics’ LED driven device.
Note: _______________________________________________________________
Non-eye safe 1300-1500nm laser driven devices will permanently damage
Net Optics’ LED driven single mode equipment. Such damage will not be
covered by warranty.

CAUTION: NEVER ATTEMPT TO VERIFY ANY FIBER OPTIC
CONNECTION BY LOOKING DIRECTLY INTO A FIBER-OPTIC PORT
OR CABLE. IF THE LIGHT SOURCE IS A NON-EYE SAFE, LASER
EMITTER, PERMANENT EYE DAMAGE MAY RESULT.
NEVER LOOK INTO THE BORE OF A FIBER OPTIC CONNECTOR!
