Cable Description

The HFBR-R/EXXYYY series of

plastic fiber optic cables are

constructed of a single step-index

fiber sheathed in a black poly-

ethylene jacket. The duplex fiber

consists of two simplex fibers

joined with a zipcord web.

Standard attenuation and extra

low loss POF cables are identical

except for attenuation

specifications.

Polyethylene jackets on all plastic

fiber cables comply with UL VW-1

flame retardant specification (UL

file # E89328).

Cables are available in

unconnectored or connectored

options. Refer to the Ordering

Notes:

1. Installation temperature is the range over which the cable can be bent and pulled

without damage. Below -20°C the cable becomes brittle and should not be subjected to

mechanical stress.

2. Short Term Tensile Force is for less than 30 minutes.

3. Short Term Bend Radius is for less than 1 hour nonoperating.

4. 90° bend on 25 mm radius mandrel. Bend radius is the radius of the mandrel around

which the cable is bent.

5. Typical data are at 25°C.

6. Propagation delay constant is the reciprocal of the group velocity for propagation delay

of optical power. Group velocity is v=c/n where c is the velocity of light in free space

(3xl08 m/s) and n is the effective core index of refraction.

7. Note that αR rises at the rate of about 0.0067 dB/°C, where the thermal rise refers to

the LED temperature changes above 25°C. Please refer to Figure 1 which shows the

typical plastic optical fiber attenuation versus wavelength at 25°C.

Force

HFBR-4503/4513 — Simplex Latching

The simplex latching connector is

designed for rugged applications

requiring a greater retention force

— 80 Newtons ( 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. Misalignment 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 CONNECTOR STYLES

HFBR-4506 — Duplex

Duplex connectors provide con-

venient duplex cable termination

and are keyed to prevent incorrect

insertion into duplex configured

modules. The duplex connector is

compatible with dual combina-

tions of horizontal or vertical

Versatile Link components (e.g.,

two horizontal transmitters, two

vertical receivers, a horizontal

transmitter with a horizontal

receiver, etc.). The duplex non-

Plastic Fiber Connector

Styles

Connector Description

Four connector styles are available

for termination of plastic optical

fiber: simplex, simplex latching,

duplex and duplex latching. All

connectors provide a snap-in

action when mated to Versatile

Link components. Simplex

connectors are color coded to

facilitate identification of trans-

mitter 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

operating temperatures or

experience frequent and wide

temperature cycling effects, the

cable/connector attachment can

be strengthened with an RTV

adhesive (see Plastic Connector-

ing Instructions for more detail).

The connectors are made of a

flame retardant VALOX UL94 V-0

material (UL file # E121562).

SIMPLEX CONNECTOR STYLES

HFBR-4501/4511 — Simplex

The simplex connector provides a

quick and stable connection for

applications that require a

component-to-connector retention

force of 8 Newtons (1.8 lb.).

These connectors are available in

gray (HFBR-4501) or blue

(HFBR-4511).

latching connector is available in

parchment, off-white (HFBR-

4506).

HFBR-4516 — Duplex Latching

The duplex latching connector is

designed for rugged applications

requiring greater retention force

than the nonlatching duplex con-

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 components. 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 connectors for

panel/bulkhead feedthrough of

HFBR-4501/4511 terminated

plastic fiber 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 compatible

with POF duplex, POF simplex

latching, or HCS connectors.

Notes:

1. Typical data are at +25°C.

2. No perceivable reduction in retention force was observed after 2000 insertions. Retention force of non-latching connectors is lower at

elevated temperatures. Latching connectors are recommended for applications where a high retention force at high temperatures is

desired.

3. For applications where frequent temperature cycling over temperature extremes is expected, please contact Agilent Technologies for

alternate connectoring techniques.

4. Minimum and maximum limit for αCC for 0°C to +70°C temperature range. Typical value of αCC is at +25°C.

5. Factory polish or field polish per recommended procedure.

6. Destructive insertion force was typically at 178 N (40 lb.).

Step-by-Step Plastic

Cable Connectoring

Instructions

The following step-by-step guide

describes how to terminate plastic

fiber optic cable. It is ideal for

both field and factory installation.

Connectors can be easily installed

on cable ends with wire strippers,

cutters and a crimping tool.

Finishing the cable is accom-

plished with the Agilent

HFBR-4593 Polishing Kit, consist-

ing of a Polishing Fixture, 600

grit abrasive paper and 3 µm pink

lapping film (3M Company,

OC3-14). The connector can be

used immediately after polishing.

Materials needed for plastic fiber

termination are:

1. Agilent 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

StripmasterTM type 45-092).

4. HFBR-4597 Crimping Tool

5. HFBR-4593 Polishing Kit

Ring

Step 1

The zip cord structure of the

duplex cable permits easy

separation of the channels. The

channels should be separated 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 off approxi-

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 connec-

tor over the end of the cable; the

fiber 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 flush with the connec-

tor, leaving a small space between

the crimp ring and the flange.

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 fiber and the fiber 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

(different color connectors are

mechanically identical).

Simplex connector crimp rings

cannot be used with duplex con-

nectors and duplex connector

crimp rings cannot be used

with simplex connectors because

of size differences. The simplex

crimp has a dull luster appear-

ance; the duplex ring is glossy

and has a thinner wall.

Step 3

Any excess fiber protruding from

the connector end may be cut off;

however, the trimmed fiber

should extend at least 1.5 mm

(0.06 in) from the connector end.

Insert the connector fully into the

polishing fixture with the trimmed

fiber protruding from the bottom

of the fixture. This plastic polish-

ing fixture can be used to polish

two simplex connectors or simplex

latching connectors simultane-

ously, or one duplex connector.

Note: The four dots on the

bottom of the polishing fixture

are wear indicators. Replace

the polishing fixture when any

dot is no longer visible.

Typically, the polishing fixture

can be used 10 times; 10 duplex

connectors or 20 simplex

connectors, two at a time.

Place the 600 grit abrasive paper

on a flat smooth surface, pressing

down on the connector, polish the

fiber and the connector using a

figure eight pattern of strokes

until the connector is flush with

the bottom of the polishing

fixture. Wipe the connector and

fixture with a clean cloth or

tissue.

Step 4

Place the flush connector and

polishing fixture on the dull side

of the 3 µm pink lapping film and

continue to polish the fiber and

connector for approximately 25

strokes. The fiber end should be

flat, smooth and clean.

This cable is now ready for use.

Note: Use of the pink lapping

film fine polishing step results

in approximately 2 dB

improvement in coupling

performance of either a

transmitter-receiver link or a

bulkhead/splice over a 600 grit

polish alone. This fine polish is

comparable to the Agilent

factory polish. The fine

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 fiber/

connector face results in a tip

diameter between 2.5 mm

(0.098 in.) minimum and 3.2

mm (0.126 in.) maximum..
