How to Choose the Right OTDR？
Choosing between F7 and RM7 depends on your project requirements and field application.
The F7 OTDR is a cost-effective, all-in-one solution designed for routine installation, maintenance, and troubleshooting. With up to 45 dB dynamic range, it covers most access and metro fiber testing needs, offering reliable performance for general field work.
The RM7 OTDR is a more advanced platform built for complex and long-distance fiber networks. It offers up to 50 dB dynamic range, along with iOLA intelligent analysis for faster event identification. Its modular design allows OPM, VFL, and laser distance meter to be detached and used independently, improving flexibility in the field.
