Product Sheet
ST/PC or ST/SPC patch-cord
Patchcords or pigtails are available in standard and custom lengths of single mode or multimode optical fiber, one or both termination assembled with ST / PC connector with convex polished (or ST / SPC, Super PC, for increasing the return loss).
Each patchcord is identified by a serial number. Insertion and return loss measures at 1310 nm are enclosed. The unitary packaging supplied is a blister with dimensions 240 x 190 x 20 mm. Other packaging available upon request.

ST/PC or ST/SPC connector
Connector with zirconia ferrule and convex polished, in plastic or metal versions. Besides its optimum optical features, this connector has been designed according to IEC 874-10 and CECC BFOC/2.5 to assure the compatibility.
It is used for interconnection in local area network (LAN), data transmission, CCTV, mainly with multimode optical fiber and in applications where the cost is an important parameter.
