Part of Nova Fiber RFTS and using our advanced iOLM technology, this compact and cost-effective remote test unit is ideal for P2P fiber monitoring.

Small and scalable

The OTH-7000 offers the most compact design on the market, delivering 16 ports in a ½ RU. Optical switch modules (256 ports) can be added to increase capacity up to 1024 ports.

Smart design for COs

Using either the fiber management system (FMS) user interface or our mobile application, activation and troubleshooting has never been simpler. And, with only 10W of power consumption, no internal fan, and an optional SFP port for Ethernet communications, this unit is great for COs.


EXFO’s innovative iOLM technology in a compact footprint reduces CAPEX by enabling centralized testing and OPEX as it allows you to remotely monitor and troubleshoot your network leading to fewer truck rolls.

Key capabilities

From construction to troubleshooting, the OTH-7000 turns traditional OTDR testing into clear, automated, first-time-right results, regardless of skill level.

P2P link certification

Qualify and certify the fiber with iOLM’s schematic view during buildout and activation. This automated, expert-level testing eliminates the need to manually configure parameters or analyze complex OTDR traces. The algorithm discovers elements on the fiber and displays pass/fail results, with loss/reflectance and distance values in a single click.

Advanced analytics

When monitoring the fiber, the user can leverage Nova Fiber’s advanced analytics, which include customizable dashboards and trending KPI metrics.

Know what’s happening before it becomes a problem.

Fault analysis and troubleshooting

Providing single-test baselining, monitoring and on-demand testing for fault analysis, iOLM mode clearly identifies customer-impacting events. Combined with the FMS mobile app and GIS software, it maps and delivers a clear analysis of these events, guiding technicians towards quick fault resolution and reducing MTTR.

Easy integration with third-party solutions

The OTH-7000 (test agent) and FMS solution can be easily integrated with third-party applications and workflows. GIS information can be extracted from Nova Fiber’s GIS database through our open APIs or via third-party solutions.

Our FMS APIs offer the exact same functionalities as the Nova Fiber web GUI and mobile app.
