Overview
The VIAVI mOSW-C1 Optical Switch Module and mISW-C1 Optical Switch Tray are fourth-generation VIAVI instrumentation-class optical switches for manufacturing test automation. They bring the performance and repeatability of VIAVI's fixed-format 19-inch rack-mount switch systems to a modular plug-in or tray format. According to the manufacturer, this can cut the size of a switching system by up to 75%, and switching is 50% faster.
Both switches belong to the MAP series LightDirect module family. The mOSW-C1 plugs into MAP-200 and MAP-300 chassis and is optimized for 1x2, 2x2 and up to 1x24 channel counts. It comes as a single- or dual-slot module with bulkhead or 2 m pigtail connections. The mISW-C1 is intended for configurations with more than 24 channels. It is factory-mounted in a 2U MAP-202C chassis for up to 72 channels, or in a 4U MAP-204C chassis for 96 to 176 channels.
Optical design
The switches are available for single-mode, OM1 and OM3 multimode, and 1310 nm and 1550 nm polarization-maintaining fiber. They use an expanded-beam design instead of reflective MEMS switching. Large channel counts are not built by cascading switches, so insertion loss, PDL and repeatability stay the same regardless of switch size. In multimode versions, the expanded beam is modally transparent and preserves IEC-specified launch conditions. VIAVI specifies both the electro-mechanical switching time and the settling time to the final insertion loss.
Input types and options
There are four input types: single common input (1C), duplex (2D), dual parallel input (2E) and 2x2 crossover (2X). The Power Trim (PTRIM) option is available on single-mode 1C versions. It adds a bidirectional in-line power monitor on the common port and up to 20 dB of programmable loss on the connected path.
Control
The switches are controlled through a SCPI remote interface. It accepts MAP series commands and is backward compatible with VIAVI SB/SC series switches. The mOSW-C1 is a drop-in replacement for the older mLCS modules. The MAP GUI provides hover-and-release channel selection, switch topology diagrams and a programmable connection table. The chassis can be accessed through remote VNC, Ethernet, GPIB or the local GUI.
