Type
SC optical fiber attenuator
When applied to SC optical fiber interface, it looks very similar to RJ-45 interface, but SC interface is more flat. The obvious difference is the inner contact. If it is 8 thin copper contacts, it is RJ-45 interface. If it is a copper column, it is SC optical fiber interface.
LC optical fiber attenuator
It is used in LC optical fiber interface to connect the connector of the SFP module. It is made of the modular jack (RJ) latch mechanism which is easy to operate.
FC optical attenuator
For FC optical fiber interface, the external strengthening method is metal sleeve, and the fastening method is screw buckle. Generally, it is used on ODF side (most used on distribution frame).
ST fiber attenuator
It is used in St optical fiber interface, commonly used in optical fiber distribution frame, the shell is round, and the fastening method is screw buckle
Characteristic
In optical fiber system, attenuator is used to reduce the light energy in the core. The most common function of attenuators is to balance the light energy between multi-core systems and reduce the saturation of receivers, because high saturation may reduce system performance. In the absorbance test, the attenuator can absorb excessive signals, because excessive signals may saturate the reference measurement. Plug type attenuator is a male female device for different connector designs. The most common uses are DWDM and EDFA, which are used to reduce the energy of optical signal and can work in the range of 1310mm ~ 1550mm.
