What is the difference Between dB & dBm?

In fiber optic communication, sometimes use dB, and sometimes use dBm. Are the two units the same? dB is a ratio of two different power levers, for example the loss in a fiber optic cable. When power is measured in linear units (mW, uW or nW), dB is calculated on a log scale using this formula: […]

Explanation of Insertion Loss and Return Loss

Insertion Loss and Return Loss are key optical parameters of of polished fiber optic connectors. These two parameters are used to evaluate the quality of fiber optic patch cables, pigtails, PON splitters etc. Insertion loss refers to the optical power loss caused when a fiber optic connector coupled with another to form a fiber optic [...]

What is FTTx?

Fiber to the x (FTTX) is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. As fiber optic cables are able to carry much more data than copper cables, especially over long distances, copper telephone networks built in the […]

Fiber Optics In Telecommunication

The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. With development of Internet technologies, traditional telecommunication system based on copper networks is becomming limited day by day. As a method of transmitting information from one place to another, optical fiber transmission is first […]
