Product Overview

Parallel optics need parallel attenuation: this MPO male-female pad inserts into a trunk or transceiver port and attenuates all 12 fibers simultaneously with tight lane-to-lane matching — indispensable for short 40G/100G SR4 links that overload receivers.

A genuinely hard-to-source part we keep in stock; APC and custom values on request.

Frequently Asked Questions

Why do short SR4 links need attenuation?

Parallel multimode transceivers at very short reach can deliver too much power, pushing receivers into saturation and causing errors — a 12-fiber pad restores every lane to the linear range in one action.

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.
