SC/UPC Fiber optic Attenuator, Male to Female, 1~25dB

SC/UPC Fiber optic Attenuator, Male to Female, 1~25dB An optical attenuator, or fiber optic attenuator, is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable.The female to male SC fiber optic attenuator and bulkhead SC fiber optic attenuator fit typical 1310nm and 1550nm single mode fiber applications. Attenuation range is from 1dB to 30dB.The SC fiber attenuators are with SC connector interface. They are with premium ceramic sleeves. Plug type SC fiber attenuator is a female to male type, while bulkhead SC fiber attenuator is a female to female type. The SC fiber optic attenuators operation wavelength range is 1240nm to 1620nm. They are used inline to decrease the optical power light in the systems for both lab and commercial applications.

Product Specification

high quality build-out attenuators ranging from 1 to 30dB. Each attenuator is made with continuous light-absorbing and metal-ion doped fiber which offers excellent environmental stability and low back reflection. The front of the attenuator is a male plug connector style that allows the attenuators to be plugged directly into receiver equipment or adaptors in patch panel. The rear is a female socket adaptor that allows a patch cord to be mated into the back of the attenuator. The attenuator is available in SC, FC, ST, LC, and MU type. In a fiber optic system, build out attenuators play an important role in controlling optical power levels in Telecommunications, CATV applications and other single mode fiber optic communications applications. As such, they must offer consistent performance over a range of operating conditions so attenuation levels remain constant and predictable.

Highly Efficient, Stable and Durable

Good interchangeability, repeatability, thermal stability and abrasive resistance; High reliability and performance. Low insertion loss: average additional loss value lower than 0.2db；High return loss: more than 1000 times insertion and extraction.

Excellent Isolating Effect, Eliminating Damage Effectively

Noise caused by group loop can be effectively restrained. Electrically, signal field is entirely isolated from host control terminal,thus accidental damage to the host controller can be highly avoided.

High Optical Performance, Excellent Mechanical Stability

Advanced grinding machine enables fiber’s center grinding offset. We adopt zirconia ferrule with alkali resistance, acid resistance, high-temperature resistance and ultrahigh-hardness, which possess high optical performance and excellent mechanical stability.
