3 hfbr-4526 , hfbr-4525 hfbr-4525 plastic fiber connector styles connector description four connector styles are avai l able for termination of plastic optical fber: simplex, simplex latching, duplex and duplex latching. all connectors provide a snap-in action when mated to versatile link components. simplex conne c tors are color coded to facilitate identifcation of tran smit ter and receiver connections. duplex connectors are keyed so that proper orientation is ensured during insertion. if the pof cable/connector will be used at extreme operat - ing temperatures or experience frequent and wide tem - perature cycling efects, the cable/connector attachment can be strengthened with an rtv adhesive (see plastic connecto r ing instructions for more detail). the connectors are made of a fame retardant valox ul94 v-0 material (ul fle # e121562). simplex connector styles hfbr-4501/4511 C simplex duplex connector styles hfbr-4506 C duplex the simplex connector provides a quick and stable connec - tion for applications that require a component-to-connec - tor retention force of 8 newtons (1.8 lb.). these connectors are available in gray (hfbr-4501) or blue (hfbr-4511). hfbr-4503/4513 C simplex latching the simplex latching connector is designed for rugged applications requiring a greater retention force 80 new - tons ( 18 lb.) than provided by a simplex nonlatching connector. when inserting the simplex latching connector into a module, the connector latch mechanism should be aligned with the top surface of the horizontal modules, or with the tall vertical side of the vertical modules. mis - alignment of an inserted latching connector into either module will not result in a positive latch. the connector is released by depressing the rear section of the connector lever, and then pulling the connector assembly away from the module housing. the simplex latching connector is available in gray (hfbr- 4503) or blue (hfbr-4513). duplex connectors provide co n venient duplex cable termination and are keyed to prevent incorrect insertion into duplex confgured modules. the duplex connector is compatible with dual combin a tions of horizontal or vertical versatile link components (e.g., two horizontal transmit - ters, two vertical receivers, a horizontal transmitter with a horizontal receiver, etc.). the duplex non-latching connec - tor is available in parchment, of-white (hfbr-4506). hfbr-4516 C duplex latching the duplex latching connector is designed for rugged applications requiring greater retention force than the nonlatching duplex co n nector. when inserting the duplex latching connector into a module, the connector latch mechanism should be aligned with the top surface of the dual combination of horizontal or vertical versatile link comp o nents. the duplex latching connector is available in gray (hfbr-4516). feedthrough/splice hfbr-4505/4515 bulkhead adapter the hfbr-4505/4515 adapter mates two simplex connec - tors for panel/bulkhead feedthrough of hfbr-4501/4511 terminated plastic fber cable. maximum panel thickness is 4.1 mm (0.16 inch). this adapter can serve as a cable in- line splice using two simplex connectors. the adapters are available in gray (hfbr-4505) and blue (hfbr-4515). this adapter is not compa tible with pof duplex, pof simplex latching, or hcs connectors. duplex crimp ring hfbr-4526

5 step-by-step plastic cable connectoring instructions the following step-by-step guide describes how to termi - nate plastic fber optic cable. it is ideal for both feld and factory installation. connectors can be easily installed on cable ends with wire strippers, cutters and a crimping tool. finishing the cable is accomplished with the avago hfbr-4593 polishing kit, consis ting of a polishing fixture, 600 grit abrasive paper and 3 m pink lapping flm (3m company, oc3-14). the connector can be used immedi - ately after polishing. materials needed for plastic fber termination are: 1. avago plastic optical fiber cable (example: hfbr- rus500, hfbr-rud500, hfbr-eus500, or hfbr- eud500) 2. industrial razor blade or wire cutters 3. 16 gauge latching wire strippers (example: ideal stripmaster tm type 45-092). 4. hfbr-4597 crimping tool 5. hfbr-4593 polishing kit 6. one of the following connectors: a) hfbr-4501/4503 gray simplex/simplex latching connector and hfbr-4525 simplex crimp ring b) hfbr-4511/4513 blue simplex/simplex latching connector and hfbr-4525 simplex crimp ring c) hfbr-4506 parchment (of-white) duplex connector and hfbr-4526 duplex crimp ring d) hfbr-4516 gray latching duplex connector and hfbr-4526 duplex crimp ring step 1 the zip cord structure of the duplex cable permits easy separation of the channels. the channels should be sepa - rated a minimum of 100 mm (4 in) to a maximum of 150 mm (6 in) back from the ends to permit connectoring and polishing. after cutting the cable to the desired length, strip of approx i mately 7 mm (0.3 in.) of the outer jacket with the 16 gauge wire strippers. excess webbing on the duplex cable may have to be trimmed to allow the simplex or simplex latching connector to slide over the cable. when using the duplex connector and duplex cable, the separated duplex cable must be stripped to equal lengths on each cable. this allows easy and proper seating of the cable into the duplex connector. step 2 place the crimp ring and conne c tor over the end of the cable; the fber should protrude about 3 mm (0.12 in.) through the end of the connector. carefully position the ring so that it is entirely on the connector with the rim of the crimp ring fush with the conne c tor, leaving a small space between the crimp ring and the fange. then crimp the ring in place with the crimping tool. one crimp tool is used for all pof connector crimping requirements. for applications with extreme temperature operation or frequent temperature cycling, improved connector to cable attachment can be achieved with the use of an rtv (ge company, rtv-128 or dow corning 3145-rtv) adhesive. the rtv is placed into the connector prior to insertion of the fber and the fber is crimped normally. the connector can be polished after the rtv has cured and is then ready for use. note: by convention, place the gray connector on the trans- mitter cable end and the blue connector on the receiver cable end to maintain color coding (diferent color connectors are mechanically identical). simplex connector crimp rings cannot be used with duplex co n nectors and duplex connec tor crimp rings cannot be used with simplex connectors because of size diferences. the simplex crimp has a dull luster appea r ance; the duplex ring is glossy and has a thinner wall.
6 step 3 any excess fber protruding from the connector end may be cut of; however, the trimmed fber should extend at least 1.5 mm (0.06 in) from the connector end. insert the connector fully into the polishing fxture with the trimmed fber protruding from the bottom of the fxture. this plastic polishing fxture can be used to polish two simplex connectors or sim plex latching connectors simultane ously, or one duplex connector. note: the four dots on the bottom of the polishing fxture are wear indicators. replace the polishing fxture when any dot is no longer visible. typically, the polishing fxture can be used 10 times; 10 duplex connectors or 20 simplex con - nectors, two at a time. place the 600 grit abrasive paper on a fat smooth surface, pressing down on the connector, polish the fber and the connector using a fgure eight pattern of strokes until the connector is fush with the bottom of the polishing fxture. wipe the connector and fxture with a clean cloth or tissue. step 4 place the fush connector and polishing fxture on the dull side of the 3 m pink lapping flm and continue to polish the fber and connector for approximately 25 strokes. the fber end should be fat, smooth and clean. this cable is now ready for use. note: use of the pink lapping flm fne polishing step results in approximately 2 db improv e ment in coupling performance of either a transmitter - receiver link or a bulkhead/splice over a 600 grit polish alone. this fne polish is comparable to the avago factory polish. the fne polishing step may be omitted where an extra 2 db of optical power is not essential, as with short link lengths. proper polishing of the tip of the fber/con - nector face results in a tip diameter between 2.5 mm (0.098 in.) minimum and 3.2 mm (0.126 in.) maximum.. hfbr-4593 polishing kit
