Instruction Sheet

Bare fiber adapters (BFA) connect single-core, single-mode or multimode bare fibers to optical
power meter detector ports in a secure manner.

To connect a fiber with the BFA-3000:

1. Remove 80 mm (3.15 in) of outer cable jacket and kevlar material.

2. Strip 30 mm (1.18 in) of buffer, then clean the fiber with alcohol or acetone.

3. Cleave the fiber. Leaving 18 mm (0.2 in) of bare fiber will ensure an optimal fit in the

BFA-3000.

4. Squeeze open the BFA-3000 by applying pressure with your thumb and index finger.

5. Place the fiber inside the opening, leaving a small length of fiber out. The fiber must be

inserted into the V groove at the front of the BFA-3000.

6. Release the sides of the BFA, allowing it to tighten around the fiber.

7. Squeeze the BFA-3000 slightly and pull back slowly on the fiber until its end is flush with the
BFA-3000’s tip, with a maximum protrusion of 0.5 mm (0.02 in). Use a magnifying lens to
help you.

Note: If the fiber protrudes too far, you may damage the cleave. If it is not far enough, you

may obtain poor coupling and/or significant power loss.

CAUTION

Excessive protrusion WILL cause damage to the detector window, and
cause permanent damage to the optical power meter.

8. Screw an FOA-3000 adapter into the channel port to use, then insert the BFA into it. Magnets
on the BFA-3000 will help to secure the connection.
