Product Overview

Drop-in receive-power control: LC build-out attenuators plug between connector and adapter, padding hot links (short-reach DWDM, OTDR ports, lab setups) to the receiver's happy range without patch changes.

Metal-ion doped fiber attenuation — flat with wavelength, stable with temperature and power. Need a different interface? Click SC or FC above to jump to that version.

Frequently Asked Questions

Where do I install a fixed attenuator — Tx or Rx side?

At the receiver: pad the incoming signal into the Rx dynamic range while keeping the transmit path clean for OTDR and monitoring.

Are the patch cords tested before shipment?

Every assembly undergoes 100% optical inspection plus insertion- and return-loss testing to IEC, TIA/EIA and Telcordia standards. Test reports are available on request.

Can length, color, jacket and connectors be customized?

Yes — length, jacket color and material (PVC / LSZH / OFNP / OFNR), cable diameter (0.9 / 2.0 / 3.0 mm) and any connector combination are OEM/ODM customizable.

What are your MOQ and lead time?

Standard configurations ship in 3–7 days with flexible MOQ. Custom OEM/ODM runs are quoted per project — send us your specs for a fast quotation.
