BWN-LB-LC-SM-2.0-PT
MPO Loopback
LC/UPC Singlemode 2.0mm Fiber Optic Loopback with Pull Tab
The BWNFiber LC/UPC Singlemode 2.0 mm Fiber Optic Loopback with Pull Tab creates a controlled optical return path between TX and RX on LC singlemode ports. The compact 2.0 mm body and integrated pull tab improve grip and extraction in high-density panels, reducing handling time and risk of disturbing adjacent connectors during transceiver testing, burn-in and field diagnostics. Built with G.657A2 fiber and UPC polish. Every unit is 100% factory optically tested before shipment.
