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 eective core index of refraction.
7. Note that aR 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 ber attenuation versus wavelength at 25°C.

Plastic Fiber Connector Styles
Connector Description
Four connector styles are avail able for termination of
plastic optical ber: simplex, simplex latching, duplex
and duplex latching. All connectors provide a snap-in
action when mated to Versatile Link components.
Simplex connec tors are color coded to facilitate identication of trans mit 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 operating temperatures or experience frequent and wide temperature cycling eects, 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 ame retardant VALOX UL94 V-0 material (UL le # E121562).
SIMPLEX CONNECTOR STYLES
HFBR-4501Z/4511Z – Simplex
DUPLEX CONNECTOR STYLES
HFBR-4506Z – Duplex
HFBR-4526Z
Duplex connectors provide con venient duplex cable
termination and are keyed to prevent incorrect insertion
into duplex congured modules. The duplex connector
is compatible with dual combina tions of horizontal, vertical or tilted packages (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, o-white (HFBR-4506Z).
HFBR-4516Z – Duplex Latching
, HFBR-4525Z
The simplex connector provides a quick and stable connection for applications that require a component-toconnector retention force of 8 Newtons (1.8 lb.). These
connectors are available in gray (HFBR-4501Z) or blue
(HFBR-4511Z). The simplex connector is compatible with
horizontal or vertical or tilted packages.
HFBR-4503Z/4513Z – Simplex Latching
HFBR-4525Z
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 package, or with the tall vertical side of the
vertical package or with top surface of tilted package.
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-4503Z) or blue (HFBR-4513Z).
DUPLEX
CRIMP RING
HFBR-4526Z
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, vertical or tilted
packages. The duplex latching connector is available in
gray (HFBR-4516Z).
Feedthrough/Splice
HFBR-4505Z/4515Z Bulkhead Adapter
The HFBR-4505Z/4515Z adapter mates two simplex
connectors for panel/bulkhead feedthrough of HFBR4501Z/4511Z terminated plastic ber 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-4505Z) and
blue (HFBR-4515Z). This adapter is not compat ible 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 Broadcom Ltd. for alternate
connectoring techniques.
4. Minimum and maximum limit for aCC for 0°C to +70°C temperature range. Typical value of aCC is at +25°C.
5. Factory polish or eld polish per recommended procedure.
6. Destructive insertion force was typically at 178 N (40 lb.).
