500m OTDR Launch Cable Box | Single-Mode Fiber OTDR Dead Zone Eliminator & Jump Cable

500m OTDR Launch Cable Box – Single-Mode Fiber OTDR Dead Zone Eliminator & Jump Cable

This 500m OTDR launch cable box is a professional fiber optic accessory that serves as both an OTDR dead zone eliminator and a fiber optic jump cable. By inserting 500 meters of single-mode fiber between the OTDR and the fiber under test, it pushes the near-end dead zone beyond the first connector and splice — enabling accurate characterization of the entire fiber link from the very first meter.

Available in a wide range of connector combinations (SC, FC, LC, ST × UPC and APC), this launch cable box is compatible with virtually any OTDR and fiber network configuration.

❓ Frequently Asked Questions

Q: Which connector type should I choose?
A: Choose the connector type that matches your OTDR port and the fiber network you are testing. UPC (Ultra Physical Contact) is standard for most telecom and FTTH applications. APC (Angled Physical Contact) is used in GPON and PON networks where higher return loss is required. Select the same connector type on both ends for best results.

Q: What is the difference between UPC and APC connectors?
A: UPC connectors have a flat end-face polish and return loss >50dB. APC connectors have an 8° angled end-face polish and return loss >60dB. APC connectors are required in GPON/PON networks to prevent back-reflection from interfering with the optical signal. UPC and APC connectors are NOT interchangeable — always match the connector type to your network.

Q: Is 500m enough to eliminate the dead zone on my OTDR?
A: For most professional OTDRs, 500m is sufficient. For OTDRs with longer dead zones, consider our 1000m or 2000m launch cable boxes.
