G.652D Low Loss Single-mode Optical Fiber Low Attenuation and Low
Dispersion
Optical Fiber is a kind of transmission media which made by glass,
the transmission form is optical pulse. The most widely used in
optical communications are single mode fiber and multimode fiber.
Features
● Single Mode optic fiber has a small diametral core that allows
only one mode of light to propagate. G.652D, G.657.A1,
G.657.A2,etc. Belong to Single Mode optic fiber. Multi-mode optic
fiber has a large diametral core that allows multiple modes of
light to propagate.
● Multi-mode optic fibers are described by their core and cladding
diameters. Thus, 62.5/125 µm multi-mode optic fiber has a core size
of 62.5 micrometres (µm) and a cladding diameter of 125 µm.
● Multi-mode optic fibers are usually described using a system of
classification determined by the ISO 11801 standard — OM1, OM2, OM3
and OM4 — which is based on the modal bandwidth of the multi-mode
fiber. The letters "OM" stand for optical multi-mode.
● Superior to corresponding standards of ITU-T
● Low attenuation and low dispersion
● Accurate geometrical parameters that insures tow splicing toss and
high splicing efficiency
● Excellent PMD performance, supporting high-speed and tong repeater
spacing Transmission system
