Anritsu Optical Cable Tester

Anritsu provides advanced optical cable testing solutions, including OTDRs and coherent OTDRs, for fault detection, loss measurement, and performance verification of both terrestrial and submarine optical networks.

OTDR Testing

Anritsu's Optical Time Domain Reflectometers (OTDRs) are designed to measure transmission loss, distance, and reflectance in optical fibers, helping locate cable cuts, connector issues, and splice losses. OTDRs are essential for installation, maintenance, and fault diagnosis of optical networks, including multicore fibers, long-distance fibers over 200 km, and PONs (Passive Optical Networks) (Anritsu America) . They support inter-core crosstalk testing for fibers with multiple cores and can analyze optical transmission characteristics efficiently.

Submarine Cable Testing

For submarine optical cables, Anritsu offers the Coherent OTDR MW90010B, capable of testing ultra-long cables up to 20,000 km with a 10 m resolution. This system uses coherent detection technology to capture waveform data, including fault location, cable loss, bending loss, and fiber length. It supports DWDM submarine cables with a tunable light source covering C-band wavelengths (1527.60–1567.13 nm) and can accurately measure cables with optical-amplifier repeaters separated by 80 km or more (GlobalSpec) . The coherent OTDR allows rapid and precise fault identification, even for engineers with minimal experience.

Applications and Benefits

Anritsu's optical testing solutions are used for:

• Network installation and commissioning: Ensuring proper fiber connections and minimal loss.
• Maintenance and fault repair: Quickly locating and diagnosing cable faults, including submarine cable damage from anchors or natural events.
• Performance verification: Measuring OTDR, chromatic dispersion, polarization mode dispersion, optical return loss, and overall signal integrity (Anritsu America) . These solutions are suitable for telecommunications, hyperscalers, and data center interconnects, providing reliable, fast, and accurate measurements to maintain high-performance optical networks (Anritsu EMEA) .

Summary

Anritsu's optical cable testing portfolio, including standard OTDRs and advanced coherent OTDRs, enables comprehensive fault detection, loss measurement, and network performance analysis for both terrestrial and submarine optical fibers. Their equipment ensures efficient installation, maintenance, and troubleshooting, supporting long-distance, multicore, and high-capacity optical networks.
