Description
Viavi 2330/21 Repair
The Viavi 2330/21 is a cable certifier – it certifies installed cabling against a standard, which means its verdict becomes a deliverable someone else relies on. It works as a main and remote pair, and both units plus the adapters they test through carry the accuracy.
June Company repairs and calibrates the Viavi 2330/21 for network installers, structured cabling contractors, and certification teams. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Viavi 2330/21 problems we fix
- Main and remote not pairing or not agreeing.
- Insertion loss or crosstalk measurement inaccurate.
- Test port or connector damage.
- Length and delay measurement errors.
- Display, keypad or front-panel faults.
- Battery or charging faults.
- GPIB, LAN, USB or remote-control faults – which breaks automated test sequences while the instrument still works from the front panel.
- Test adapter worn – a consumable interface whose wear produces failures indistinguishable from genuinely faulty cabling.
FAQs
Are the measurements verified after repair? Yes, against reference standards, with the measured results documented and returned with the instrument.
Cabling I know is good is failing certification. Tester or cable? Check the adapter first. Worn adapters are the most common cause of false failures and a far cheaper fix than rewiring.
Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
