What are the common structures for fiber optic quick connectors?
fiber optic fast connector has two types:
1.direct installing type. the structure of this type fast connector is very simple,so it is easier to make with a lower cost.It has short points:it has strict requirements on the fiber diameter,the endface of cutting surface,the strength of holding fiber,the fiber length of cleaving.Any of them will affect the loss of connection.Thus the return loss is bad.It requres the operater be skillful. The product structure principle is as follows:
fiber optic fast connector direct installing type
The direct installing fast connector more used in urgent reparing of the cable connection while less used in ftth fiber connection to the home.
2.pre- terminated fast connector:the fiber is pte installed in the ferrule and polished.when install,the end user only need well cut the fiber with fiber cleave and use hand to connect cable.There is matching liquid in the ferrule fange,and well polished thus have better return lods result and easy install. The product structure principle is as follows:
fiber optic fast connector Pre-Embedded type
With a low insertion loss<0.5dB and high return loss>45dB it is more reliable and stable and widly used in fiber to the home.
