Description

1.1 SCOPE

This specification covers the design requirements and performance standard for the supply of optical fiber cable. This specification covers the general requirements and performance of cable which our offering including optical characteristics, mechanical characteristics and geometrical characteristics.

1.2 CABLE DESCRIPTION

Loose tube cable is a design that has high tensile strength and flexibility in a compact cable size. Our loose tube cable provides excellent optical transmission and physical performance.

1.3 QUALITY

We ensures a continuing level of quality in our cable products through several quality control programs including ISO 9001 and all the materials have passed REACH and ROHS.

1.4 RELIABILITY

We ensure product reliability through rigorous qualification testing of each product family. Both initial and periodic qualification testing are performed to assure the cable’s performance and durability in the field environments.

1.5 REFERENCE

2. OPTICAL FIBER
The optical fiber is made of high pure silica and germanium doped silica. UV curable acrylate material is applied over fiber cladding as optical fiber primary protective coating. The detail data of optical fiber performance are shown in the following table.

OFS G.652 fiber use special spun device successfully controlled the value of PMD, and make sure that it keeps stable in cabling.

Approved by optical communication products ministry of quality supervision and inspection center, the connection between OFS fiber in and outside is good .The single-end connect-loss won’t be over 0.1dB and the double-end connect-loss is all little than 0.05dB.
Apply to non-relay communication network. Features: proof test >1%
