Dual 1x2 Optical Switch Module 1250-1650 nm Low Insertion Loss Lightwave Switch Module for 816x Systems

The Keysight (Agilent) N7752A is a dual 1x2 optical switch module that plugs into the 8163B, 8164B and 8166A lightwave measurement system mainframes. Each module houses two independent 1x2 switches, giving four switched output paths in a single half-rack slot, which makes it a compact building block for automated fibre test stations, multi-device characterisation and DWDM component measurement.

With low insertion loss, excellent repeatability and fast switching, the N7752A lets a test system route optical signals between sources, devices under test and power meters without manual re-cabling. The switch is controlled from the mainframe front panel or remotely by SCPI commands over GPIB, LAN or USB, so it integrates directly into lab automation software.

• Two independent 1x2 optical switches in a single module
• 1250–1650 nm single mode fibre wavelength range
• Low insertion loss, typically 0.6 dB per path
• High switching repeatability for stable long-term measurements
• Fast switching time of 10 ms or less
• High return loss for low back-reflection in sensitive test setups
• Front panel and SCPI remote control through the 816x mainframe
• Pre-owned module, tested in full working condition with 30-day warranty

• Automated fibre component test stands and production lines
• DWDM component and module characterisation
• Routing between tunable laser sources, DUT and optical power meters
• Multi-channel optical power monitoring and switch matrix build-up
• Laboratory automation in optical transceiver and photonics R&D

One pre-owned Keysight Agilent N7752A dual 1x2 optical switch module, tested and verified in full working condition, supplied in protective export packaging. Mainframe, tunable laser sources and power meter modules are available separately if you are building a complete 816x test station. Connector type and options vary between units — please confirm your requirement and we will match the right module for your setup.
