Product Description
This cable has been designed to meet the Technical Requirements as mentioned in
the specification documents, it fulfills the design for the applications desired
therein. The design is based on stranded loose tube which provides stable performance
over a wide temperature range and is compatible with any telecommunications-grade
optical fiber. This Cable has been designed for both Duct and Direct Buried applications,
design strength and rodent protection has been provided by using Polyamide –
Nylon and Rodent Resistant Glass Rovings as first (inner) sheath. The
stranded loose tubes contain thixotropic jelly for protection of the optical fibers
as required. It is designed on Jelly base, contains the excellent quality filling
compound for stopping ingress/transport of water into the cable. This is a 48 fiber
single mode metallic free all di-electric composite cable having 24 fibers of
G.652.D and 24 fibers of G.655.C, it facilitates easy and economical
installation.
Length markings in meters for easy determination of cable length. Extra Strength
cable can also be delivered with Peripheral Strength Members.
