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.

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 transmitter 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 Connectoring 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
HFBR-4503/4513 — Simplex Latching
HFBR-4525
latching connector is available in
parchment, off-white (HFBR4506).
HFBR-4516 — Duplex 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).
HFBR-4526
The duplex latching connector is
designed for rugged applications
requiring greater retention force
than the nonlatching duplex connector. 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).

Duplex connectors provide convenient duplex cable termination
and are keyed to prevent incorrect

modules. The duplex connector is

transmitter with a horizontal
receiver, etc.). The duplex non-

mates two simplex connectors for

cable in-line splice using two
simplex connectors. The adapters
are available in gray (HFBR4505) 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 accomplished with the Agilent
HFBR-4593 Polishing Kit, consisting 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: HFBRRUS500, HFBR-RUD500,
HFBR-EUS500, or HFBREUD500)
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 approximately 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 connector 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 connector, 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 transmitter 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 connectors and duplex connector
crimp rings cannot be used
with simplex connectors because
of size differences. The simplex
crimp has a dull luster appearance; the duplex ring is glossy
and has a thinner wall.
6
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 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 polishing fixture can be used to polish
two simplex connectors or simplex
latching connectors simultaneously, or one duplex connector.
Note: The four dots on the
bottom of the polishing fixture
are wear indicators. Replace
the polishing fixture when any
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..
