- Typical industry practice is 12–24 months. Many quality systems default to 12 months. For legacy optical switches that affect measured insertion loss or system uncertainty, an annual (12‑month) interval is prudent. If your quality system allows and stability is demonstrated, a 24‑month interval may be acceptable.

Quick Overview
- What it is: A legacy HP/Agilent optical fiber switch module used to route optical signals in automated lightwave test systems.
- Typical use: Automated multi‑port optical testing, cycling through DUT ports, simplifying loss/IL/PDL/return‑loss measurement workflows.
- Status: Obsolete (out of production and no longer supported by the OEM; available on the secondary market).
A Keysight (Agilent/HP) 81595A Optical Switch doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the 81595A, the specification limits, and the standards behind them.
Expert calibration verifies performance against traceable references, flags drift before it becomes failure and documents every adjustment. This isn’t box‑checking or sticker‑slapping. Its precision enforced. If your work depends on numbers you can defend, Rogue Calibration helps find the right calibration service provider for you.
