Relevant vendor listings describe this as a 1650 nm, ultra‑high‑resolution OTDR module and list it among Viavi’s modular OTDR offerings for field platforms.
Typical Applications and Capabilities
- In‑service fiber monitoring and testing using an out‑of‑band 1650 nm test wavelength to avoid disturbing live traffic.
- High‑resolution fault location and connector/splice inspection on short spans, metro, and access links where fine spatial resolution is required.
- Compatibility with passive WDM/filter modules for adding or blocking OTDR wavelengths in live networks.
What the public listings do not always show (and what to confirm)
- Dynamic range (dB), pulse widths, event/attenuation dead zones, and connector type (APC/UPC) are not consistently listed in rental or summary pages and must be confirmed from the official Viavi datasheet or product configurator.
- Exact platform compatibility and firmware requirements (which OneAdvisor or T‑BERD chassis revisions support this module) should be verified with Viavi or your equipment vendor.
