OM1 62.5 / 125 um Graded-index Multimode Optical Fiber with a 62.5um Core Diameter

The 62.5 / 125 um Multimode Bare Optical Fiber is a graded-index multimode optical fibre with a 62.5um core diameter and a 125um cladding

diameter, The optical fibre is designed for use at 850nm and /or 1300nm.

Application for this optical fibre are local area networks(LAN),video data and /or voice transimission using laser or light emitting diodes at 850nm

or 1300nm. Because of this nature of the manufacturing process, the optical fibre offers the highest bandwith available in the market .

Coating

The optical fibre is coated with a double layer of UV curable acrylate, type DLPC7, Designed for more stringent tight-buffer cable applications .

The optical fibre also performs perfectly in loose buffer cable applications , the opical fiber also performs pefectly in loose buffer construcion

and demostrates a high resistance to microbending.

The coating offers an excellent stable coating strip force over a wide range of environment conditions. In tight buffer applications the entire coating construction (tight buffer and primary coating) is in general very easy to strip off. Coating stripping leaves no residues on the bare glass fibre.


A bare fiber, a core with its cladding surrounded by a coating-is still very sensitive to the adverse environment regardless of

how perfect the coating is . Thus , in practice, you will find a fiber only in some protective enclosure, which is called fiber-optic cable,

Since optical fiber is the main transmission medium in modern telecommunications .

Bare glass fibers are based on silica or other glass materials. The glass surface is susceptible to abrasion and mechanical flaws. To protect the cable from the environment, the buffer coating or jacket fits over the core and cladding.

The diameter ranges from 250μm to 900μm, usually 250um for single mode and multimode fibers, but 400um is also very common in polarization maintaining fibers. It provides mechanical protection while allowing for flexibility in the fiber.

The buffer coating is usually made of a soft or hard plastic such as acrylic or nylon. Kevlar is a popular choice for the jacket material. It is strong and used to bundle and protect the loose tubes or fibers in the cable.

Kevlar protects the fibers when the tension is placed on the cable. The color of this jacket typically depends on the type of fiber, single mode fibers typically wear a yellow jacket and multi-mode fibers wear an orange jacket.
