Variable Fiber Attenuators

For Pakistani procurement and engineering teams, the specification provides a practical basis for checking compatibility before production is requested. The variable attenuator series puts an adjustable, calibrated loss element between two connectors: an FC mechanical model covering 1-30 dB and an in-line SM/MM model covering 0-60 dB with LC/SC/FC/ST interface options. One instrument sweeps the specifications that would otherwise require a drawer full of fixed attenuators - the standard tool for receiver sensitivity testing and connection margin verification.

For Pakistani campus and data hall builds, too much attenuation is as harmful as too little; pick the nearest standard figure that lands the receiver inside its window with margin to spare.

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.

Store spare attenuators capped and bagged, and clean each end face before making the connection.

Ordering Details and Factory Support

All attenuators in this series are optically verified before packing: attenuation figure, return loss and end-face condition are checked on each unit. State the attenuation figure, connector series, polish grade and body style with the request, and the factory confirms the specification with the quotation. For Pakistan, a clear port or maintenance schedule helps us confirm the correct factory-built configuration before supply.
