Factors to Be Considered for Fiber Optic Termination

Date:06-06-2018

Among those famous dome fiber closure manufacturers and suppliers, Green Telecom Tech Co.,Ltd can offer you customized DOME Fiber Closure and fiber optic termination, in this article, you will know the important factors that should considered for fiber optic termination.

Insertion Loss of Fiber Optic System: Fiber optic cabling systems support various communications technologies like Gigabit Ethernet, local area networking (LAN) and CATV (community access television). No matter what types of networks it supports, the communication devices have a limitation for maximum channel insertion loss measured in units of decibels (dB). Optical fiber channel insertion loss usually occurs when an active transmitter is linked to an active receiver via terminated fiber optic cables, splicing points and fiber optic connectors. The quality of fiber optical links’ terminations has an impact on the channel insertion loss. Poor quality terminations often cause more loss than high-performance terminations. An optical system will fail due to excessive insertion loss.

Return Loss of Optical System: Return loss is the power of the optical signal that returns towards the optical source against the direction of signal propagation, which is mainly caused by Fresnel reflections and Rayleigh back scattering. Communication systems can be impaired by an excessive amount of reflected optical power, which could alter the transmitted signal to an extent that is not the power level received by the receiver. Generally, components like connectors and mechanical splices are specified as reflectance, and system sensitivity is specified as return loss.

Fiber Optic Termination Methods: Nowadays various fiber optic connectors are available such as LC, SC and MTP connector, so are termination methods existing for different connector types. Common termination methods include no-epoxy-no-polish (NENP) connector, epoxy-and-polish (EP) and splicing.

Of course, cost is another aspect when selecting a termination method. In a word, the proper optical fiber termination method should be chosen to ensure easy system installation as well as meet required insertion loss and reflectance values prescribed by either industry standards or link loss budget, or both.
