6 November 1975 Access Couplers For Multiterminal Fiber Communication Systems
Author Affiliations +
Optical "T" and Multiple "T" access couplers designed for tapped trunk line multi-terminal communication systems which use bundles of multimode fibers as the transmission media have been investigated. The particular coupler designs tested used bent pyrex rods for bifurcation and scrambling. Coupler throughput losses (not counting packing fraction losses) are 1.5 - 2.5 dB. The bent rod optical "T" and multiple "T" access couplers must be used with high N.A., low packing fraction loss fibers.
