Glass optical fiber cables transmit light through tiny glass fibers resulting in very little signal loss. For that reason and more Glass optical fibers are ideal for harsh environments maintaining a smooth operation even when exposed to mechanical stress, high temperatures or chemical substances.

From Single mode OS1/ OS2 to Multi mode OM3/OM4, TransPro’s GOS Cables portfolio offers our partners a variety of terminations and lengths to exactly match their specifications.

Our GOS division offers our partners with the following cabling configurations:

Single mode:

Fiber single mode copy

A single-mode optical fiber (SMF) is an optical fiber designed to carry light only directly down the fiber – the transverse mode. The cable usually carries higher bandwidth than multimode. The small core of the single mode fiber and single light-wave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and the highest transmission speeds of any fiber cable type.

Single mode cables comes in two standards:

OS1 – for indoor uses such as campuses, Data Centers, etc. with ISO/IEC 11801 quality assurance.

OS2 – for outdoor or loose tube uses such as streets, underground/burial, etc.  with ISO/IEC 24702 quality assurance.

Both standards comes in a 1, 2, 12, 24 fiber configurations.


fiber multimode

A Multi-Mode fiber cable is an optical fiber mostly used for communication over short distances. Light waves dispersed into numerous paths, or modes, as they travel through the cable’s core.

Because of its high capacity and reliability, multi-mode optical fiber generally used for backbone applications in buildings.

Multi-Mode cables comes in two standards:

OM3 – with a core size of 50µm and an optimization for laser based equipment that uses fewer modes of light the OM3 fiber optic cable is capable of running 10 Gigabit Ethernet at lengths up to 300 meters.

OM4 – a further improvement to OM3. It too uses a 50µm core but it supports 10 Gigabit Ethernet at lengths up 550 meters and it supports 100 Gigabit Ethernet at lengths up to 150 meters.

Both standards comes in a  1, 2, 12, 24 fiber configurations.
