A small form factor fiber optic connector called the Fiber Jack and defined
in Telecommunications Industry Association (TIA) FOCIS-6 is introduced tha
t reduces the center spacing of the ferrules from 1.27 mm (0.5 in.) as in a
duplex SC to 0.63 mm (0.25 in.) to enable it to fit within a standard RJ-4
5 port spacing. The Fiber Jack (FJ(TM)) connector is the combination of two
de facto standards: 2.5 mm ferrules and the RJ-45 style plug and jack. The
standard 2.5 mm diameter ferrules take advantage of industry investment in
termination equipment and techniques. The plug and jack design eliminates
the use of an adapter such that the jack mounts flush with an outlet or pat
ch panel. The FJ is designed for both multimode and single-mode fiber and h
as been tested according to EIA/TIA (Electrical Industry Association/Teleco
mmunications Industry Association) defined Fiber Optic Test Procedures (FOT
Ps), the results of which are included. The Fiber Jack interface was develo
ped by Panduit Corporation and is marketed as the OPTI-JACK(TM) fiber optic
connector. (C) 1998 Society of Photo-Optical Instrumentation Engineers. [S
