Launch Cable, SM G.657 A1, 150m, SC-ST R240-SL-SCST

Key Features

Single-mode G.657.A1 fiber for low-bend sensitivity and reliable field performance
150 meters length ideal as an OTDR launch/receive cable for long spans and accurate event capture
Pre-terminated SC ST connectors for broad instrument compatibility and rapid setup
Rugged outer jacket, molded strain reliefs and reinforced boots for extended field durability
Color-coded ends and clear length markings for fast identification and inventory control
Low typical attenuation for accurate loss and splice measurements
Spool-friendly, lightweight construction for convenient transport and storage

This 150-meter launch cable is built on single-mode G.657.A1 fiber, engineered specifically for OTDR launches and field characterization where low-bend loss and repeatable measurements matter. The cable’s G.657.A1 fiber minimizes bend sensitivity compared with standard SM fiber, helping technicians obtain reliable event location and loss data even when routing the cable around trays, ducts, or tight bends. Pre-terminated SC to ST connections make the cable immediately usable with most OTDR instruments and field gear, reducing setup time and the risk of connector handling errors.

Designed for everyday field use, the assembly features a resilient outer jacket, molded strain reliefs, and reinforced boots to protect terminations during deployment and transport. The spool-friendly, lightweight design stores compactly and winds securely for easy deployment between test sites or in a workshop. Color-coded ends and clear marking improve workflow speed, while typical low attenuation and consistent launch performance help ensure high-quality, repeatable splice and connector loss measurements.
