1. INTRODUCTION

This instruction sheet (IS) covers AMP OPTIMATE DNP fiber-optic connectors. which are designed for use with 1000-~m plastic fibers.

The connectors can be applied to the fib~ without the need for pOlishing or the use of epoxy. They are available in simoiex (single-channel) and duplex (two­channell versions. for connecting a fiber either to another fiber or to an active device.

Designer's Kit 228084- 1 contains an assortment of DNP connectors. 5 m of cable. a hot knife. a cuning fixture. and a cable-stripping tool.

The following toOlS are recommended for terminating DNP connectors:

A hot knife. such as AMP 228085-1. or an equivalent. such as Weller SP23HK.

Wire strippers for 20 AWG wire or 1000­fiber.

Pliers.

2. DESCRIPTION (Figure l' DNP connectors are available in simplex and du;::: versions. A retention clip. which is barbed both ins and out. engages the jacket of the fiber and the ins of the plug or splice. The split tip of the plug OP4 enough to allow Slightly larger fibers to pass throul while V-grooves on the inside of the tip hold fibers centered. Fiber-to-fiber connections are me either in a splice or in a bUlkhead-mounting ree tacle. The splice does not require use of a plug VI

the fiber. Fibers can also be mated to active devil (sources and detectors). which are mounted ir simplex device mount ISDM).

Simplex plugs mate with both simplex and duplex receptacles. The receptacles allow disconnectable fiber· to· fiber connections. The splices make perma­nent connections.

3. PLUG TERMINATION

The following is the recommended procedure for terminating a fiber in a plug. The procedure is the same for both simplex and duplex connectors, except that the procedure is repeated for the second plug in the duplex connector. While a hot knife does not have to be used to trim the fiber, its use will greatly improve the optical and mechanical characteristics of the termination.

1. If the retention clip and plug are separate, insert the clip, V·notched end first. into the rear of the plug. The end of the clip should be flush with the end of the plug. See Figure 2.

2. Strip about 1/8 to 1/4 inch of jacket from the fiber. Set wire strippers for 20 AWG wire.

. C...uflO,... 00 not nick or cut the fiber. If your wire stnppers do not have a 20 A WG setting, use a small piece of fiber as a guide for setting the strippers.

3. Use pliers to push the stripped cable into the plug until the cable bottoms and excess fiber

extends out the nose of the plug. Be sure the jacket does not enter the slotted portion of the plug. See Figure 2.

4. Pull back slightly on the cable to ensure that the barbs on the retention clip engage the jacket and plug .

5. Slide the plug into the cutting tool fixture, as shown in Figure 3 for a simplex plug.

I WUNIN(; In the next several steps in which the fiber is trimmed with the hot knife, keep fi,ngers away from the cutting tool fixrure. Hold the plug as shown in Figure 3. AI/ow the fixrure to cool before removing it.

6. While firmly holding the plug, pass the hot knife over the highest area (cutting surface) of the cutting tool fixture. This cuts off the excess fiber . See Figure 3A.

7. Place the flat side of the hot-knife blade in the lower area (melting suriaceJ of the fixture. Press downwards with the blade to melt the remaining fiber flush with the end of the plug. The fiber should form a small rivet in the plug to aid retention. See Figure 3B.

8. After the fixture has cooled, remove it.

9. Inspect the plug for proper termination. The end of the fiber should form a rivet flush with the end of the plug.

10. The plug is now ready to be mated with a simplex receptacle, duplex receptacle, or SDM. See Paragraph 5 for the recommended layout and mounting of the SDM or receptacle. Push the plug. nose first, into the receptacle or SDM until it latches tightly.

4. SPLICE TERMINATIONS (Figure 41

The following is the procedure for connecting two fibers in a splice.

1. Strip about 1132 in. of jacket from the fiber.

IS 2974

2. Press the flat of the hot knife against the end of the fiber to form a rivet on fiber.

3. Start the retention clip onto the end of the cable. Place the clip end on a hard, flat suriace and press down on the cable until the end of the fiber is flush with the end of the clip.

4. Using pliers, grip the cable directly behind the clip and push the cable into the splice until the back end of the retention clip is flush with the end of the splice.

5. Repeat Steps 1 through 4 with the other fiber.

5. BOARD AND BULKHEAD LAYOUT (Figure 5)

Figure 5 shows the recommended layout for the pc board for mounting the SDM and active device. The SDM can be mounted vertically or horizontally. It also shows the cutout dimensions for mounting simplex and duplex receptacles in a bulkhead. Secure either the SDM or receptacles with No.2-56 screws.
