EXFO MAX-720C-SM1 OTDR – Professional Single-Mode OTDR with 36/35dB Dynamic Range
The EXFO MAX-720C-SM1 is a professional-grade single-mode OTDR from EXFO, positioned between the MAX-715B and MAX-730C in the MaxTester lineup. With a 36/35dB dynamic range at 1310/1550nm — 6dB more than the MAX-715B — the MAX-720C delivers greater measurement margin for testing longer fiber spans, higher-loss networks, and more demanding applications, while maintaining the same trusted EXFO platform: 7-inch outdoor-enhanced touchscreen, 256,000 sampling points, 12-hour battery life, and a built-in 1625nm live port filter for passive live fiber monitoring. Available in UPC (EI) and APC (EA) connector versions, with FC or SC interface options.
Why Choose the EXFO MAX-720C-SM1?
- 36/35dB Dynamic Range (1310/1550nm): 6dB more than the MAX-715B — enabling testing of longer fiber spans and higher-loss networks with greater measurement confidence
- 1m Event Dead Zone: Detects events as close as 1m apart for reliable characterization of connectors, splices, and events in standard fiber installations
- 256,000 Sampling Points: Ultra-high sampling resolution (down to 0.04m) for precise event location and characterization across the full 160km distance range
- Built-in 1625nm Live Port Filter: Highpass filter (>1595nm, isolation >50dB) enables passive monitoring on live fiber without interrupting active services
- 7-Inch Outdoor-Enhanced Touchscreen: 800×480 TFT display optimized for bright outdoor conditions — the largest display in the handheld OTDR industry
- 12-Hour Battery Life: Full day of field testing on a single charge (Telcordia TR-NWT-001138)
- 2GB Internal Storage (20,000 Traces): Ample onboard storage for project documentation and acceptance testing records
- Multi-Language Support: English, Spanish, French, and more for international deployment teams
- Calibration Certificate Included: Ships with calibration certificate for traceable measurement accuracy
- 1-Year Warranty
Ideal Applications
- Long-haul and metro fiber network construction and acceptance testing
- FTTH / PON network installation and troubleshooting
- Telecom network maintenance and fault location requiring higher dynamic range than MAX-715B
- Enterprise and data center fiber infrastructure testing
- Passive live fiber monitoring via 1625nm filter

Frequently Asked Questions
Q: What is the difference between the MAX-720C-SM1 and MAX-715B?
A: The MAX-720C-SM1 offers a higher 36/35dB dynamic range (vs. 30/28dB on the MAX-715B), providing 6dB more measurement margin for testing longer fiber spans and higher-loss networks. Both share the same 7-inch touchscreen, 256K sampling points, 1m event dead zone, 160km distance range, and 12-hour battery. The MAX-715B-OI version includes iOLM software; the MAX-720C-SM1 includes standard OTDR software only.
Q: Does the MAX-720C-SM1 include iOLM software?
A: No. The MAX-720C-SM1 includes standard OTDR software only. If you require iOLM (intelligent Optical Link Mapper) for automated link characterization, consider the MAX-715B-OI or MAX-730C which include iOLM.
Q: What does the 1625nm live port filter do?
A: The built-in 1625nm highpass filter (isolation >50dB) allows passive monitoring of live fiber at 1625nm without interrupting active services. Note: this is a passive filter, not an active 1625nm OTDR wavelength — for full 1625nm OTDR testing, see the MAX-730C.
Q: What connector options are available for the MAX-720C-SM1?
A: The MAX-720C-SM1 is available with UPC (EI suffix) or APC (EA suffix) connector polish, and with FC or SC connector interface. For connector adapters compatible with the MAX-720C, see our EXFO EUI-89 (FC) and EUI-91 (SC) adapter listings.
Q: What warranty does the EXFO MAX-720C-SM1 come with?
A: The MAX-720C-SM1 ships with a 1-year warranty and calibration certificate. For support or bulk pricing, contact us at info@splicermarket.com.
