Jewel Ferrule Alignment System

Cannon's

patented*

optical

contacts

allow

the

use of all standard fibers via the field-proven

jewel ferrule alignment system in a size 16 pin

socket

contact.

The

jewel

ferrule

system

provides

precise

alignment

regardless

fiber

size,

accommodates

fiber

tolerances,

elim-

inates the requirement for a minimum end gap,

and alloys for spring loading of contacts.
