Description
Overview
The EXFO 715B-M1-EA MaxTester is a dual-wavelength OTDR designed for fiber contractors, OSP technicians, and telecom operators who need a field-portable platform for FTTx deployment, PON qualification, and fiber backbone characterization. It operates at 1310 and 1550 nm with dynamic ranges of 30 dB and 28 dB respectively, a 1 m event dead zone, and supports distance ranges up to 160 km — making it applicable across access, metro, and long-haul fiber testing workflows. This Grade B unit from OMIWAA provides access to a fully operational MaxTester 715B-M1-EA at a substantially lower cost than new, with all functions verified prior to listing and a 2,000 m G.652 launch cable included.

Why Buy From Omiwaa
OMIWAA physically receives, inspects, grades, photographs, and documents every unit before it is listed for sale. This EXFO MaxTester 715B-M1-EA was handled directly by OMIWAA — it was not sourced through a broker, listed on consignment, or drop-shipped from a third party. OMIWAA owns and ships every item in its inventory, and condition grading is based on direct physical assessment, not seller-reported information.
Common Use Cases
The EXFO MaxTester 715B-M1-EA is used across a range of professional fiber optic testing applications requiring dual-wavelength OTDR measurements in field and indoor environments.
- FTTx and PON network qualification including end-to-end loss measurement, splice loss characterization, and connector reflectance verification on access fiber infrastructure
- Fiber backbone testing and link certification across metro and long-haul routes requiring dynamic range up to 30 dB and distance coverage to 160 km
- Acceptance testing of newly deployed fiber links with high-resolution trace acquisition and USB/LAN export for documentation and handover reporting
- Network maintenance and fault localization on live or dark fiber using the integrated live fiber detection port and 1 m event dead zone for close-event resolution
