SC Fiber Optic Attenuator
We supply 1dB to 30dB range SC fiber optic attenuators. These attenuators are widely used in Erbium Doped Fiber Amplifiers, Dense Wave Division Multiplexers and Overpowered fiber optic systems. Infinifiber.com SC fiber optical attenuators work with 1250nm to 1625nm range.

LC Fiber Optic Attenuator
LC fiber optic attenuator is a passive device used to reduce the amplitude of a light signal without significantly changing the wave form itself. LC fiber optic attenuators are used in Dense Wave Division Multiplexing (DWDM) and Erbium Doped Fiber Amplifier (EDFA) applications where the receiver cannot accept the signal generated from a high-power light source.

FC Fiber Optic Attenuator
FC fiber optic attenuators feature a proprietary type of metal-ion doped fiber which reduces the light signal as it passes through. This method of attenuation allows for higher performance than fiber splices or fiber offsets, which function by misdirecting rather than absorbing the light signal. Infinifiber.com FC fiber optic attenuators are capable of performing in the 1310, C and L Bands.

ST Fiber Optic Attenuator
ST fiber optic attenuators are capable of withstanding over 1W of high power light exposure for extended periods of time, making them well-suited to EDFA and other high-power applications. Low Polarization Dependent Loss (PDL) and a stable and independent wavelength distribution make them ideal for DWDM. We supply UPC and APC types ST fiber optic attenuators.

MU Fiber Optic Attenuator
We supply MU fiber optic attenuators that are used to reduce the optical light power in MU connections in fiber optic systems. Two version MU fiber optic attenuators available include UPC and APC types, working for single mode optical fiber.

Fiber optic attenuator technique data
UPC type return loss 50dB or greater
APC type return loss 60dB or greater
Working wavelength 1310nm or 1550nm

About fiber Optic Attenuator
Sometimes in the fiber optic network, people need to reduce the fiber optic light power level when it is transmitted from one equipment to another; fiber optic attenuator is a device for this function. The unit “dB”, usually from 1dB fiber optic attenuator to 20dB fiber optic attenuators, measures fiber optic attenuation level. This is called a fixed value fiber optic attenuator, each piece of the fiber attenuator the attenuation rate is fixed. There are female to female and female to male type attenuators, the latter is also called a plug type attenuator.

Adustable fiber Optic Attenuator
There are also variable fiber optic attenuator , usually is inline type, with an adjustable unit on the attenuator to change its attenuation level to a certain amount according to its capacity.
