ITU-G.657B3

Type:
Bend Insensitive Single-mode Optical Fiber (G.657.B3)

Standard:
The fiber complie with or exceed the technical specifications in ITU-T G.657.A1/A2/B2/B3.

Feature:
Minimum bend radius 7.5mm, superior anti-bending property;
Fully compatible with G.652 single-mode fiber. Full band (1260~1626nm) transmission;
Low PMD for high bit-rate and long distance transmission. Extremely low micro-bending attenuation, applicable for all optical cable types including ribbons;
High anti-fatigue parameter ensures service life under small bending radius.

Application:

All cable constructions, 1260~1626nm full band transmission, FTTH high speed optical routing, optical cable in small bend radius, small-size optical fiber cable and device.

Optical Cable Factory

In 2004, GL FIBER established the factory to produce optical cable products, mainly producing drop cable, outdoor optical cable, etc.

GL  Fiber now have 18 sets of coloring equipments, 10 sets of secondary plastic coating equipments, 15 sets of SZ layer twisting equipments, 16 sets of sheathing equipments, 8 sets of FTTH drop cable production equipments, 20 sets of OPGW optical cable equipments, and 1 paralleling equipment And many other production auxiliary equipments. At present, the annual production capacity of optical cables reaches 12 million core-km (average daily production capacity of 45,000 core km and kinds of cables can reach  1,500 km) . Our factories can produce various types of indoor and outdoor optical cables ( such as ADSS, GYFTY, GYTS, GYTA, GYFTC8Y, air-blown micro-cable, etc.). the daily production capacity of common cables can reach 1500KM/day, the daily production capacity of drop cable can reach max. 1200km/day, and the daily production capacity of OPGW can reach 200KM/day.
