Intellinet Network Solutions Singlemode Duplex BIF LC/LC 7 m Yellow 9/125 µm G.657.A1

Singlemode Duplex BIF Patch Cable

This 7 m singlemode duplex patch cable uses OS2 fiber with a 9/125 µm core and G.657.A1 bend-insensitive glass from Corning. It terminates in LC/UPC connectors at both ends and carries a yellow OFNR-rated jacket. The design suits interconnect and cross-connect work in entrance facilities, telecommunications rooms, data centres and desk-side links. Each unit ships with its factory test report and a lifetime warranty.

Verify Connector Polish and Fiber Mode

Confirm that your equipment uses LC ports expecting UPC polish rather than APC, as the angle differs and mismatched polish raises return loss. Ensure the link budget is calculated for OS2 singlemode fiber, not multimode, because core diameter and modal dispersion are incompatible. Check that the 2.0 mm jacket fits your patch-panel routing and cable-management channels before ordering.

Sustained Load Behaviour

The G.657.A1 bend-insensitive construction limits additional attenuation when the cable is routed around tight corners or held in dense trays for long periods. Low-loss Corning glass and UPC end-faces keep insertion loss and return loss stable during continuous 40G Ethernet transmission. The OFNR jacket meets riser flame ratings, so performance does not degrade when installed in vertical shafts where temperature varies.
