The EXFO MaxTester 730C is a professional PON OTDR designed specifically for testing passive optical networks (PON) where multiple customer drops share a single fibre via optical splitters — a challenge that standard OTDRs cannot handle. Its 39dB dynamic range and 0.6-metre event dead zone allow it to test through 1×128 optical splitters to individual ONT endpoints, identifying faults at any point in the PON network from the OLT port outward. The 7-inch touchscreen with EXFO's iOLM guided workflow transforms complex OTDR traces into simple pass/fail results that field technicians can interpret without specialist training. The industry standard OTDR for Safaricom, Telkom, and ISP fibre network maintenance.
