FiST

Fiber Splice Kit

A patch, not a depot kit — single channel, one job. Not a permanent fix, and we do not pretend otherwise: it keeps the system in the fight until proper maintenance can occur.

What's in the kit

1

Fusion splicer

Single channel — one job: get the line back up.

2

Splice-ready pigtails

Connectors and fiber types matched to your systems.

3

Consumable tray

Wipes, cleaning fluid, sleeves, and a VFL to verify.

4

Heat shrink & protective sleeve

Protects the joint and carries the load across the repair.

5

Jacket stripper, Kevlar shears, cleaver

Prep the fiber in-hand — a clean cleave every time.

In the field — five steps, under an hour

01

Prep the fiber — strip and clean the damaged end

02

Fusion splice to a pigtail

03

Sleeve the splice to protect the joint

04

Verify the link with the VFL

05

Back in operation

<1 HR

02 · The need & the challenge

One broken strand takes the system down

Aircraft, ground systems, command posts and comm nodes all run on fiber. One broken strand or one damaged connector brings a system down — and there is no internal way to fix it.

Every path back to operational is a bad one.

Three ways to get a line back — all bad

01

Wait for a new assembly

Custom tactical assemblies aren't stocked. A requisition triggers a fresh procurement: solicit, award, build, deliver.

~217 days

Requisition to delivered assembly. The slowest 10% run 406+ days.

02

Hope a vendor bids

These are not commodity buys. The industrial base behind custom fiber optic assemblies is thin, and it's stretching.

64%

Of custom assembly awards drew a single offer — and 55% of recent solicitations went unawarded on the first pass.

Cannibalize another system

Pull a working cable from a less-critical platform. One system comes up, another goes down.
