Keysight's popular N7745A optical power meters with eight power-sensor channels provide increased throughput and operational efficiency to meet today's challenges in manufacturing. Designed for characterizing optical multiport components, these optical power meters offer industry-leading solutions for device connectivity, high-speed measurement data acquisition and fast data transfer for post-processing. The multiport power meter enables fast measurement solutions for all multiport devices; for example multiplexers, PON splitters, wavelength selective switches (WSS) and ROADMs, as well as compact setups for simultaneous testing of multiple single-port devices.

The N7745A power meter achieve a level of space-saving channel density that is new in the industry. This is complemented by the ease of integrating multiple instruments into a single setup with parallel programming over the LAN or USB connections.

The multiport power meter is an LXI compliant instrument, developed using LXI Technology. LXI, an acronym for LAN eXtension for Instrumentation, is an instrument standard for devices that use the Ethernet (LAN) as their primary communication interface. Hence, it is an easy-to-connect instrument with integrated Web browser that provides convenient configuration of the instrument’s functionality.

With this new power meter comes the unprecedented N7740 fiber connectivity concept, which is a quadruple adapter (quad-adapter) with a snap-on quick-locking mechanism. The device to be tested can be connected to the quad-adapter in a comfortable ergonomic working position, even while the instrument is measuring another device. Then the quad-adapter can quickly be snapped on, to provide repeatably high-precision connections. Use of the quad-adapter simplifies aligning connector keys, especially for rack-mounted instruments and makes it easier to connect ports in the desired order, helping to avoid errors and connector damage.
