Get High-Quality Direct Burial Fiber Optic Cable From Our Factory!

The cable offered by GDTX are designed, manufactured and tested according to the standards as follows:

ITU-T G.652.D	Characteristics of a single-mode optical fiber
IEC 60794- 1- 1	Optical fibre cables-part 2: Generic specification-General
IEC 60794- 1-21	Optical fiber cables- part1-21-Generic specification-Basic optical cable test procedure-Mechanical test methods
IEC 60794- 1-22	Optical fiber cables- part1-22-Generic specification-Basic optical cable test procedure-Environmental test methods
IEC 60794-3- 10	Optical fibre cables-part 3- 10: Optical fiber cables-part 3- 10: Outdoor cables-Family specification for duct and direct buried optical communication cables

Optical fibre cables supplied in compliance with this specifications is capable to withstand the typical service condition for a period of twenty-five (25) years without detriment to the operation characteristics of the cable.

Item	Value
Operation temperature	-40 ºC～+70 ºC
