Agilent HFBR-4531/4532/4533/4535

Crimpless Connectors for Plastic Optical

Fiber and Versatile Link

Data Sheet

Description

The HFBR-453x series

connectors are an enhanced

version of the HFBR-4501 and

HFBR-4503 low-cost connectors

for plastic optical fiber, which

are compatible with Agilent’s

versatile link series transmitters

and receivers. The innovative

design uses a simple, snap-

together concept which

eliminates the need for

crimping. This connector not

only saves the user labor and

tool cost, but reduces the yield

loss due to installation error.

The HFBR-453x series

connectors are available in two

styles: latching and non-latching.

For a duplex connector, two

non-latching simplex connectors

can be snapped together. The

connectors are made of a

rugged, flame retardant plastic

which is good for industrial and

other harsh environments. The

HFBR-453x series connectors

are for use with Plastic Optical

Fiber only.

Features

•Requires No Crimp Ring or

Crimping Tool

•Durable ULTEM® Plastic

Material (UL File #E121562)

•Same Low Cost as HFBR-4501/

4503 Series Connectors

•Excellent Retention Force

•Symmetry in Nonlatching

Connector Gives Simplex/Duplex

Functionality with the Same Part

Applications

These connectors can be used for

any application in which plastic

optical fiber is used including:

•Industrial Control and Voltage

Isolation

•Automotive Networks

•Proprietary System Interconnects

•Gaming Equipment

•Medical Equipment

•Telecommunications

•Datacommunications

ULTEM® is a registered trademark of the General Electric Corporation.

The HFBR-453x Series of

connectors are available in three

colors; black, blue and grey. The

ability to select colors to match

Transmitters and Receivers

makes it easier for the User to

differentiate between fiber

connections especially when

there are a large number.

Termination Guide

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

installations. Connectors can be

easily installed on cable ends

with standard tools such as wire

strippers and cutters.

Finishing the cable is

accomplished with the Agilent

HFBR-4593 Polishing Kit,

consisting of a polishing fixture,

600 grid abrasive paper and 3

mm pink lapping film (3M

Company, OC3-14). The

connector can be used

immediately after polishing.

The following materials are

needed for plastic fiber

termination:

1. Plastic optical fiber cable

(Example: HFBR-RUD500)

2. Wire cutters or scissors

3. 16 gauge wire stripper

(Example: Ideal Stripmaster

type 45-092)

4. HFBR-4593 polishing kit

(optional)

5. Crimpless connectors

Step 1: Stripping the Fiber

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, polishing and

cable end flexibility.

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.

When using the duplex

connector arrangement, the

separated duplex cable should

be stripped to roughly equal

lengths on each cable end.

For the non-latching version

(HFBR-4531), the same

connector is used for simplex

and duplex arrangement. No

crimping is necessary. The top

half of the connector will snap

into the ferrule half to secure the

fiber.

Step 2: Putting on the Connector

Place the connector on each end

of the fiber, and slide the

connector down until the fiber

jacket stops it. The fiber should

protrude no less than 1.5 mm

(0.06 in) from the end of the

connector.

To install simplex connectors

flip the top half of the connector

over and snap it into the ferrule

half (with your fingers). When

the top half latches inside the

body of the ferrule half, proper

connector-to-cable attachment is

achieved.

For duplex connector

installation place one connector

on top of the other, so that the

top half of each connector is

over the ferrule half of the

opposite connector.

Manually press connectors

together in the center of the

arrangement. Then latch by

pressing on the sides of each

connector. As with the simplex

version, connectors are secured

when top halves latch into the

ferrule halves.

Step 3: Trimming and Polishing

Any fiber in excess of 1.5 mm

(0.06 in) protruding from the

connector end should be cut off

with wire cutters or scissors.

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 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.

Press the polishing tool down on

the 600 grit abrasive paper.

Polish the fiber using a figure

eight pattern 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: Finishing

Place the flush connector and

polishing fixture on the dull side

of the 3 µm pink lapping film

and continue to polish the fiber

in the same figure eight pattern

for approximately 25 strokes.

The fiber end should be flat,

smooth and clean.

HFBR-4593 Polishing Kit

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

for short link lengths.

Connector Mechanical Characteristics

Note:

1. Storage and operating temperatures refer to the ranges over which the connectors can be used when not subjected to mechanical stress.

Installation temperature refers to the ranges over which connectors may be installed onto the fiber and over which connectors can be connected and

disconnected from the transmitter and receiver modules.
