LC to LC Duplex Singlemode Fiber Loopback Cable 2 Pack OS2 9/125 UPC Plug for SFP Transceiver Testing

Singlemode LC to LC Duplex Loopback Tester, 2 Pack Product overview A pair of pretested singlemode LC to LC duplex loopback testers designed for reliable fiber transceiver and port verification. Built for repeated field use with durable components and simple plug and play operation. Key benefits Faster troubleshooting: Instantly loop transmit to receive for quick confirmation of transceiver and port function without complex setup. Field ready: Each cable is factory tested for signal continuity and strength, reducing time spent diagnosing installation issues. Durable construction: Stronger jacket material and ceramic ferrules resist wear from repeated connections and unclipping on job sites. Ready to protect: Includes extra LC dust caps so connectors stay clean when not in use. Clear compatibility: Designed specifically for singlemode LC transceivers and connectors, helping avoid confusion with multimode systems. Features and specifications Pack quantity: 2 loopback testers Connector type: LC to LC duplex, LC UPC termination Fiber type: Singlemode, 9/125 micron; compatible with G657A1 and OS2 singlemode equipment Construction: Ceramic ferrules for stable optical contact and a reinforced jacket for durability Pretested: Each cable is tested for signal strength and continuity before Reusable: Engineered for repeated insertion and removal without damaging the cable or ports Includes: Extra LC dust caps for each connector How it solves common problems Identifies bad transceivers or ports quickly by creating a known good loop for signal verification. Helps locate signal loss introduced during installation by isolating transceivers and patch panel ports. Reduces downtime by providing a simple test tool technicians can use on site without additional equipment. Suggested use scenarios 1) Data center rack maintenance: Use the loopback tester to verify SFP and SFP plus transceivers and confirm LC port continuity during routine rack audits. 2) Field installation verification: After running singlemode fiber lines, plug the LC loopback into the transceiver to confirm transmit and receive channels are properly connected. 3) Transceiver troubleshooting: Swap a suspected faulty transceiver into a known good port and use the loopback tester to determine whether the issue is the transceiver or the network port. Compatibility notes Designed for singlemode SFP and SFP plus transceivers, LC data center server rack connectors and similar LC singlemode fiber applications. Not suitable for multimode fiber transceivers or for use in vehicle conversion applications. What is included Two singlemode LC duplex loopback testers Extra LC dust caps for each connector This tester kit provides a practical, durable solution for routine fiber checks, transceiver testing, and port verification where singlemode LC connections are used.
