DSIT fibertester SE-13013377

Fiber optic network issues can bring your entire operation to a halt, but pinpointing faults without the right tools is a frustrating guessing game. The DSIT SE-13013377 Fiber Optic Tester eliminates that uncertainty by combining an optical power meter, a stabilized light source, and a visual fault locator in one compact, field-ready unit. Whether you're certifying new installations, troubleshooting existing links, or performing routine maintenance, this tester gives you accurate, repeatable measurements across all common fiber types and wavelengths.

Who is it for

Network technicians, installers, and maintenance crews working with single-mode and multi-mode fiber will appreciate the SE-13013377's versatility. It's ideal for enterprise LAN/WAN environments, data centers, telecom outside plant, and FTTx deployments. Contractors who need to validate link loss, locate breaks, or verify continuity will find it indispensable for daily use.
