The Minimum Bend Radius of a simplex patch cable is typically 30 mm. Avoid over-bending the

cable as this will result in a high optical loss.

Connect SC/APC cable to SC/APC modules and FC/APC cable to FC/APC modules only. To

connect SC/APC, locate the connector key. Align key and keyway then gently push the plug

into the adapter until a click is heard and the connector locks. To disconnect SC/APC just pull

back the “square” collar. Replace the dust caps on both the receptacle and the cable plug.

To connect FC/APC optical connectors, remove the dust caps and align the white ceramic

center ferrule on the cable connector with the mating receptacle. There is a key (lug) on the side

of the ferrule, which must match the keyway (gap) in the receptacle shroud. When they are

aligned, gently push the plug home and finger tighten the knurled collet nut onto the threaded

receptacle. To disconnect, unscrew the knurled collet on the plug and gently withdraw the plug.

Replace the dust caps on both the receptacle and the cable plug. (keep in mind the Minimum

Bend Radius of Fiber Optic Cables is 50mm.)

Cleaning Optical Connectors

Optical connectors MUST be cleaned before use. Most performance issues are due to dirty

fibers. For more details please read the cleaning instruction which accompanies the connector

cleaning kit you use (see https://www.fiberinstrumentsales.com/).

When cleaning and connecting the fiber optic cables, never look directly into the end of the fiber.

Power off both the Head End and the Remote units while connecting and cleaning. Remember

light is also coming from the unit at the other end of the fiber.

Always cap the connector with the plastic cover when not in use.

Never touch the fiber tip with your finger.

Optical Zonu RF over Fiber transceivers use a variety of angle cut optical connectors: SC/APC,

FC/APC and LC/APC. They must mate with their corresponding connectors and adaptors. The

plastic boot color on cable side of the connector is GREEN indicating the connector is angle cut

APC.

Always clean both sides of the mating

surfaces. For bulkhead connectors use a

pen tool.

Dry cleaning, no special solutions or

cleaner, is the preferred method.

Solvents might attack epoxy and some

optical cleaners for lenses may leave

residues. If a cleaner is used, only

reagent-grade 99% isopropyl alcohol

should be used. Never use cotton swabs

or cloth it will leave threads behind. As a
