Description
QAP G652D SM‑500M‑SCALCU 500M OTDR Launch Cable SM 9/125µm SC/APC‑LC/UPC
Overview
The QAP G652D SM‑500M‑SCALCU is a 500-meter OTDR launch cable built with high-grade G.652D 9/125µm singlemode fiber, terminated with SC/APC to LC/UPC connectors. This fiber ring is ideal for bridging the OTDR dead zone and enabling accurate event detection on both ends of the fiber link. Its connector pairing supports diverse fiber test setups where mismatched interfaces are present. The unit is designed for field use and functions as both a launch cable and a receive cable.
Tri‑Tek Electronics is an authorized QAP distributor and maintains local inventory at our Mesa, AZ retail location. We offer full manufacturer warranty coverage, expert support, and immediate product availability to customers throughout Phoenix, Tempe, Chandler, and the greater Arizona region.

Application Example
Versatile Mid-Length OTDR Testing
This 500-meter launch cable is perfect for scenarios where a longer buffer is needed than typical 150–300m cords but shorter than 1km. A technician testing a fiber link between a panel and a remote terminal can use the SC/APC end at the OTDR and the LC/UPC end at the fiber input, ensuring precise measurements with minimal loss. As a receive cable, it enables accurate event capture at the far end of the fiber, especially in hybrid connector environments.
Its mid-range length makes it highly versatile for service providers, enterprise networks, and low voltage integrators working across mixed topologies.
