PRO BEAM Jr. EB low–profile D–hole bulkhead

connectors are designed to be installed onto 900– m

buffered fiber with a length less than 2 meters for use

in transceiver connection.

The connector must be assembled using a bulkhead

connector shell kit, an EB insert assembly kit, and

ferrule assembly kit (one for each fiber or channel).

Sample part numbers are given in Figure 1. The

combination of the kits selected is based on the

diameter of the cable, the mode and quantity of

fibers, and the operating wavelength of the system.

These connectors are designed to be rear panel

mounted.

Reasons for reissue of this instruction sheet are

provided in Section 7, REVISION SUMMARY.

Each kit contains the components shown in Figure 1.

The EB insert assembly kit is shipped with a white

protective label on the back (end opposite the lens) of

the EB insert which is installed immediately after final

testing to keep the channel cavities clean. The EB

insert is ready for assembly as shipped.

Do not touch the lens of the EB insert with your

fingers or with any tools

Always have the protective cap installed or the

connector mated to prevent contamination to

the EB insert assembly

The following tools and materials are necessary for

preparation, assembly, inspection, and maintenance

of the connector and fibers. Follow the operating

Assemble the connector using a laminar

flow table in a clean environment meeting the

requirements of International Organization for

Standardization (ISO) 14644–1 (Class 5),

“Cleanrooms and Associated Controlled

Environments, Part 1.” Make sure that all components

are free from contamination.

Proceed as follows:

1. If the protective tubing

is not

installed onto the

buffered fiber, proceed with the following:

a. Pre–heat the environmental test oven to a

temperature between 100 and 105 C.

b. Cut the protective tubing to a length of

approximately 10% longer than the length of the

buffered fiber.

c. Stress–relieve the protective tubing by

placing it in the environmental test oven for 45

to 60 minutes.

d. Slide the prepared protective tubing over the

buffered fiber, allowing approximately

100 mm of the buffered fiber to be exposed.

e. Pre–heat the heat cure oven to 100 C.

f. Slide the components shown in Figure 2 over

the buffered fiber and onto the protective tubing.

Make sure to orient each component as shown.
