Overview
The VIAVI T‑BERD/MTS‑2000V2 fitted with the E4146QUAD OTDR module and integrated power meter is a compact, handheld fiber test solution that combines multimode and single‑mode OTDR capability in one module. It supports 850/1300 nm multimode and 1310/1550 nm single‑mode testing, includes a built‑in CW light source and power meter, and is optimized for premises, enterprise, access, metro, and wireless backhaul work.
Key Technical Highlights
- Wavelengths: 850 nm, 1300 nm, 1310 nm, 1550 nm.
- Dynamic range: Up to ~26 dB (multimode) and up to ~37 dB (single‑mode) depending on wavelength and pulse settings.
- Display range: 0.5 m to 260 km configurable per test.
- Sampling resolution / cursor: 4 cm sampling; 1 cm cursor resolution for precise event location.
- Data points: Up to 128k–256k depending on firmware and platform.
- Event / attenuation dead zones: Very short event dead zone for accurate short‑link testing; attenuation dead zone optimized for premises links.
- Optical interfaces: Interchangeable adapters (FC, SC, LC, ST) and dual ports for MM and SM where applicable.
- Form factor / weight: Handheld module, approximately 128 × 134 × 40 mm, ~0.4 kg.
What it does in the field
- Install and certify fiber links across premises and access networks using both multimode and single‑mode wavelengths.
- Locate faults (breaks, high‑loss splices, macrobends) quickly with high resolution and multi‑wavelength traces.
- Perform loss and power checks without swapping instruments thanks to the integrated CW light source and power meter, enabling continuity, insertion loss, and ORL checks from the same port.
- Generate reports and pass/fail results on the handheld using platform software such as Smart Link Mapper and FastReport to speed handoffs to operations teams.
Why this configuration is valuable
- One tool for MM and SM: The quad module removes the need to carry separate MM and SM OTDRs, saving time and reducing tool swaps.
- Faster workflows: Integrated source/power meter and on‑board reporting reduce test steps and paperwork.
- Accurate short‑link testing: Short dead‑zone and fine sampling resolution make it ideal for patch panels, jumpers, and short premises links.
