Step 1

Cut cable to desired length, making sure to include contact

termination length and desired service loop length (Note:

service loop not applicable for ber termination.)

Step 2

Slide BacNav OFS backshell assembly onto cable-end being

terminated. Slide insert-retainer and o-ring or adapter (as

applicable) onto cable following the backshell. (Note: Adapter

may be coupled to backshell.) Unscrew and separate intermediate

compression nut and gland assembly from main body assembly.

(See gure 1)

Step 3

Prepare cable end for termination.

a. Determine cable jacket strip length. For precise

determination, it is recommended to terminate a connector

using a minimum strip length, then mark the cable jacket

at the required distance behind the main body assembly.

Length will include contact termination length, desired

service loop length (not applicable for ber) and eective

main body assembly length (includes installed adapter

length if present). (See gure 2)

b. Remove outer cable jacket exposing cable-shield (braid) or

Kevlar® strength members (ber-optic applications).

Shielded electrical cable applications: Remove any water-

block material from cable-shield. Trim cable shield to 3-4

inch length (optional) then fold back at over outer cable

jacket and tape down.

Fiber-optic applications: Leave Kevlar® strength members

long, fold back over outer cable jacket and tape down

Step 4

Prepare conductor/bers and terminate contacts/OFCs according

to specic connector requirements.

Step 5

Insert contacts/OFCs into connector according to specic connector

requirements.

Step 6

Move backshell main body assembly (with adapter if present,

or insert-retainer/o-ring if present) towards cable end to mate

with connector. Position insert-retainer and o-ring if applicable,

then thread backshell/adapter-to-connector coupling nut onto

connector ensuring proper alignment/orientation with respect

to connector master-key, and verifying proper engagement of

clocking teeth or splines as the coupling nut is hand tightened.

(See Figure 4)

Step 7

Verify cable jacket strip length, and terminate cable-shield/

Kevlar® strength members. (Refer to banding tool instructions for

additional details).

Shielded electrical cable applications: End of cable jacket should

measure " ± " from conical end of main backshell body assembly

to cable jacket (with service loop length contained inside backshell).

(See gure 2) Un-tape cable-shield and fold forward over conical

end and banding platform, ensuring even 360° distribution.

Prepare termination-band and installation tool, positioning

over shield in the center of the banding platform. (See gure 5)

Complete band termination, ensuring cable jacket end remains

” ± ” from conical end of main backshell body. (See gure 6)
