specifications
Amphenol’s 944 Series fiber optic FC connectors
effectively terminate optical fiber in a variety of
network applications. The connectors are secured
using a threaded coupling nut, providing a
significant increase in pull-out performance. The FC
connectors also feature an internal cavity and epoxy
injection tube that virtually eliminates the
possibility of improper epoxy application, thus
providing higher manufacturing yields.
Every aspect of the connector system is precision
manufactured to produce reliable and consistent
performance. The 944 series is available in
tunable or non-tunable PC versions for flexibility
in specific performance requirements. The FC/APC
connector system features a tight-fit keyway that
prohibits the possible mis-mating between FC/PC
and FC/APC connectors.
944 Series FC Connectors
Insertion Loss: ≤ 0.15dB typical, singlemode
≤ 0.30dB typical, APC
≤ 0.35dB typical, multimode
Return Loss: Ultra (UPC) ≤ -55dB*
Angle (APC) ≤ -65dB*
Durability: < 0.2dB change, 500mating cycles
