1. what is difference between single mode and multimode Fiber?
Single mode means the fiber enables one type of light mode to be propagated at a time. While multimode means the fiber can propagate multiple modes
2. When we say 62.5 /125 fiber What does 62.5 or 125 mean?
In terms of physical properties, the difference between these two fiber types is the diameter of the core-the light-carrying region of the fiber-signified by the numeric nomenclature. In 62.5/125 fiber, for example, the core has a diameter of 62.5 microns and the cladding diameter is 125 microns.
3.what is the difference between duplex and simplex in fiber cable
Simplex fiber is most often used where only a single transmit and/or receive line is required between devices or when a multiplex data signal is used (bi-directional communication over a single fiber). A duplex fiber cable consists of two strands of glass or plastic fiber.
4.What is OS1?
OS1 cabled optical fiber is appropriate for indoor and universal tight buffered cable constructions, which are mainly deployed in internal building/campus networks, as well as internal cabling within telecom exchanges and data centres.
5.Whats is OS2?
OS2 cabled optical fiber is appropriate for outdoor and universal loose tube solutions, which would include external plant and most backhaul networks.
6.How Many Types of Multimode Fiber OM1,OM2,OM3,OM4 &OM5?
7.Types of Fiber Optic Cables Used in Networks:
Single Mode Cable. As its name indicates, the single-mode cable has only one mode or ray of light. ...
Multi-Mode Cable. Multi-mode cables can carry multiple signals, and they have a core diameter of 50 or 62.5 µm. ...
Plastic Optical Fiber (POF)
8.What are the 4 properties of optical fiber?
The mode of propagation and refractive index of the core is used to form four combination types of optic fibres as follows:
Step index-single mode fibres.
Graded index-Single mode fibres.
Step index-Multimode fibres.
Graded index-Multimode fibres.
