SW-10XX: Optical Switch with Power Meter

The SW-10XX series of modules provides fast, hitless 1xN optical switching with optical power monitoring in a small, portable, cost-effective solution for use in remote switching or network protection/monitoring applications as well as an R&D environment.  This bidirectional optical switch is available in configurations including 1x4, 1x6, 1x8, 1x12, 1x16 and 1x24.

The module includes an optical power monitor which uses a 2% bidirectional tap to minimize insertion loss.  An onboard temperature sensor allows the power monitoring circuitry to be calibrated during production test to provide measurement resolution of ±0.01 dB and linearity (relative accuracy) of ±0.1 dB over an operating temperature range of 0°C to 40°C.    

The SW-10XX can be USB powered and connects directly to a Windows based computer which runs the graphical user interface (GUI) software.  The USB GUI provides complete control and status of all optical switching and power monitoring functions. 

An AC/DC adapter is also provided to power the SW-10XX when its Ethernet interface is used to allow the SW-10XX to be controlled using either Static or Dynamic IP addressing.  In this configuration, a standard HTML browser (e.g. Firefox, Chrome, Internet Explorer) provides the user interface and the various control and status HTML pages are integrated into the microcontroller’s firmware.

It is also possible to perform remote, time stamped, optical power and status data logging using SW-10XX applications written for Windows and for Linux. These applications use the IP address of the module to gather the optical power and status data every second and write that data, along with the host computer’s system time, to a .csv file. This allows the user to remotely collect and track optical power information over long periods of time.
