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
DUPLEX CONNECTOR STYLES
HFBR-4506 – Duplex
Four connector stylesare 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
Duplex connectors provide con­venient duplex cable
termination and are keyed to prevent incorrect insertion
into duplex configured modules. The duplex connector is
compatible with dual combina­tions 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-latching connector is available in parchment, off-white (HFBR-4506).
HFBR-4516 – Duplex Latching
, HFBR-4525
DUPLEX
CRIMP RING
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).
HFBR-4503/4513 – Simplex Latching
HFBR-4525
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 (HFBR4503) or blue (HFBR-4513).
HFBR-4526
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).
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 inline 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 Avago 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.
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.
Finishing the cable is accom­plished with the Avago 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. Avago 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
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 (off-white) Duplex Connector
and HFBR-4526 Duplex Crimp Ring
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.
Step 1
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).
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.
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.
d) HFBR-4516 Gray Latching Duplex Connector and
HFBR-4526 Duplex Crimp Ring
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.
Step 4
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
dot is no longer visible. Typically, the polishing fixture 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 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.
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
Avago 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/con­
nector face results in a tip diameter between 2.5 mm (0.098
in.) minimum and 3.2 mm (0.126 in.) maximum..
