Due to holiday season, the orders from December, 24th to December, 29th and January, 1st will be processed on the business days after these dates.
The MU/UPC Fiber Optic Attenuator Dual Wave 3dB Doped (Part number: ATN-1432-03) from Senko is a MU/UPC Fiber Optic Attenuator with 3.0dB loss.
A fiber optic attenuator is a passive device used to reduce the amplitude of a light signal without significantly changing the wave form itself. This is often a requirement 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.
Senko’s Premium Attenuators passed all required mechanical testing including the extended life 5,000 hour environmental testing. This dope fiber technology MU/UPC attenuator 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. Senko attenuators are capable of performing in the 1310, C and L Bands, has a low back reflection and a high durability over high power. Senko 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. One piece housing construction for better side load performance. Low Polarization Dependent Loss (PDL) and a stable and independent wavelength distribution makes them ideal for DWDM.
Note: For full wavelength type (1270 ~ 1650) Attenuation tolerance will be 1db to 10db 0.7db and 11db to 30db ±10%.
