Fiber optic sealed feedthrough
FSA Conax Technologies

Conax has adapted our proven soft sealant capability to include the ability to compress a soft sealant material around the outside diameter of a fiber optic cable. The fiber optic cable is encased within a rugged stainless steel sheath that protects the cable from damage during the sealing process. This sheath is then placed through a sealing gland. This process allows the fiber optic cable to be sealed without the use of epoxies and with minimal out-gassing.

The fiber optic feedthrough sub-assembly can be used with various Conax sealing glands, including multiple hole fittings.

Features:
-Wide range of connector terminations: ST, SMA, FC, FC/APC, FC/PC and SC/APC

-Adaptable to customer-supplied fiber
-Can seal outside jacket diameters from 400 to 1040 microns
-Protection Tubing: Standard furcation tube (black in color) is constructed of
a polypropylene inner tube with a dried Kevlar¨ Aramid yarn strength member
and a 3.0 mm outer polyethylene jacket.
