Performance of quality huawei fiber optic connectors

2021-03-29 16:25

Huawei fiber optic connectors are devices for detachable connection between optical fiber and optical fiber. It precisely connects the two end faces of the optical fiber so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and the Its intervention in the optical link minimizes the impact on the system, which is the basic requirement of huawei fiber optic connectors. To a certain extent, huawei fiber optic connectors affect the reliability and performance of the optical transmission system.

According to the different transmission media, huawei fiber optic connectors can be divided into common silicon-based optical fiber single-mode and multi-mode connectors, as well as other optical fiber connectors such as plastics as the transmission medium; according to the structure of the connector, it can be divided into: Various forms such as FC, SC, ST, LC, D4, DIN, MU, MT, etc.

The performance of huawei fiber optic connectors is first of all optical performance. In addition, the interchangeability, repeatability, tensile strength, temperature, and the number of insertions and removals of the optical fiber connectors must also be considered.
(1) Optical performance: The optical performance requirements of huawei fiber optic connectors are mainly the two most basic parameters of insertion loss and return loss.
Insertion loss, or connection loss, refers to the loss of link effective optical power caused by the introduction of connectors. The smaller the insertion loss, the better, and the general requirement should be no more than 0.5dB.
Return loss refers to the ability of the connector to suppress the reflection of link optical power, and its typical value should not be less than 25dB. In the actual connector, the pin surface has been specially polished, which can make the return loss greater, generally not less than 45dB.
(2) Interchangeability and repeatability
The huawei fiber optic connectors are general passive components. Generally, the same type of fiber optic connectors can be used in any combination and can be used repeatedly. The additional loss introduced by this is generally within the range of less than 0.2dB.
(3) Tensile strength
For the finished huawei fiber optic connectors, the tensile strength is generally required to be no less than 90N.
(4) Temperature
Generally, huawei fiber optic connectors must be able to be used normally at a temperature of -40oC~+70oC.
(5) Mating times
The huawei fiber optic connectors used can basically be plugged and unplugged more than 1,000 times.
