•
If the fiber optic connector is clean, cover the connector with a protective dust cover
until ready for use.
• If the fiber-optic connector is not completely clean, continue with the next step.
9.
Clean the fiber end by moving the cleaning pad back and forth across the fiber end
several times. If using a swab, gently rotate the swab as you wipe across the end face.
10.
Immediately dry the fiber end with a clean, dry, lint-free cleaning pad or lens paper.
11.
Discard the optical cleaning pads and lens paper.
12.
Use a filtered, dry, compressed air dust remover. Aim the duster at a shallow angle to
the fiber end face and blow across the connector end-face from a distance of 6 to 8
inches.
13.
Verify that the fiber-optic connector is free from dirt and dust. To inspect the connector,
use an optical fiber scope that uses an indirect image converter or a filtered optical
instrument of optical density (OD) sufficient to reduce the exposure levels below the
appropriate maximum permissible exposure.
14.
Once the fiber is clean, cover the connector with a protective dust cover until ready
for use.
You have successfully completed this procedure.

Fiber Breakout for UFM6 QSFP+ Ports
The QSFP+ transceivers used on the UFM6 are parallel single mode transceivers that
have four parallel 10-Gbps lanes. To provide access to these individual 10-Gbps channels,
Juniper Networks has adopted GigaLight's fiber breakout solution, which consists of a
fiber cassette and rack.
The QSFP+ transceiver connects to the GigaLight fiber cassette through a single cable
(consisting of multiple single-mode fibers), which is split within the cassette into individual
10-Gbps fiber pairs that are accessible from the cassette faceplate (
Figure 53 on page 226 ).
The cassette can be mounted into a GigaLight 1U GigaC Rack (holds 12 cassettes).
