N7744A 4-Channel Optical Multiport Power Meter N7745A 8-Channel Optical Multiport Power Meter

Data Sheets

General Information

Up to 8 power meter channels in a small package

Keysight Technologies’ new N7744A and N7745A optical power meters with four or eight power-sensor channels provide manufacturing customers with increased through­put and operational efficiency to meet today’s challenges in manufacturing.

Designed for optical multiport applications

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 postprocessing. 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.

Save significant rack space

These power meters achieve a level of space-saving chan­nel density that is new in the industry, and simplify fiber handling for many-port device testing. This is comple­mented by the ease of integrating multiple instruments into a single setup with LAN or USB connections.

A reliable four-port optical connection with the new one click quad-adapter

With this new power meter comes the unprecedented N7740 fiber connectivity concept, which is a quadruple adapter with a snap-on quick-locking mechanism. The de­vice to be tested can be connected to the quad-adapters in a comfortable ergonomic working position, even while the instrument is measuring another device.

The quad-adapters can be quickly snapped on to the instrument, to provide reliable and repeatable high-precision connections. Use of the quad-adapters 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.

This quad-adapter also fits into Keysight’s standard bare fiber connectivity solutions 81000BI. The one click zeroing adapter N7740ZI allows quick and reliable 4-port zeroing of the new power meters.

Code compatible with your existing Keysight optical power meters

The new optical multiport power meter is code compatible with the Keysight optical power meter sensors and optical power meter heads. Simply replace up to eight existing single power meter modules with the new N7745A optical multiport power meter, adapt the new instrument configu­ration and run your existing application software.
