Variable Fiber Attenuators

The variable attenuator family puts an adjustable, calibrated loss element between two connectors: an FC mechanical version covering 1-30 dB and an in-line SM/MM version covering 0-60 dB with LC/SC/FC/ST interface options. One instrument sweeps the values that would otherwise require a drawer full of fixed attenuators - the standard tool for receiver sensitivity testing and link margin verification.

Variable Fiber Attenuators

FC Single Mode Variable Fiber Optic Attenuator, 1-30dB
1-30db attenuation, variable, 1260-1620(sm)nm, ion-doped fiber element, factory tested.

LC/SC/FC/ST Variable Fiber Optic VOA In-Line Attenuator, SM/MM, 0-60dB
0-60db attenuation, 1310-1550(sm)/850-1300(mm)nm, ion-doped fiber element, factory tested.

All attenuators in this family are optically verified before packing: attenuation value, return loss and end-face condition are checked on every unit. State the attenuation value, connector family, polish grade and body style with the enquiry, and the factory confirms the specification with the quotation.
