Datasheet

Overview

The VIAVI mISW-C1 Optical Switch Tray is part of the MAP series optical switch solutions, built on the fourth generation of VIAVI instrumentation-class optical switch technology. It brings the performance and repeatability of the larger fixed-format 19-inch VIAVI rack-mount switch systems into a tray format, and according to VIAVI can reduce the size of switching systems by as much as 75% while increasing switching speed by 50%.

The mISW-C1 is optimized for switch configurations with more than 24 channels. The tray is selected together with its chassis and mounted at the factory: the 2U MAP-202C is used for lower channel counts, and the 4U MAP-204C accommodates up to 176 switch outputs. The tray is not modular; access is provided for service only.

Switches are not cascaded to create large channel counts, so insertion loss, polarization-dependent loss and repeatability are the same regardless of switch size. Expanded-beam technology keeps multimode versions modally transparent, preserving IEC-specified launch conditions for insertion-loss testing. VIAVI specifies both the electro-mechanical switching time and the settling time needed to reach a stable insertion loss.

Configurations and control

The mISW-C1 supports single common input (1C), duplex (2D) and dual parallel (2E) input types, which can reduce the number of switches a test system needs. An optional Power Trim (PTRIM) function on single-mode 1C versions adds a bidirectional in-line power monitor and up to 20 dB of programmable loss on the connected path. The SCPI remote interface accepts MAP series style commands and keeps compatibility with the VIAVI SB/SC series optical switches. The tray is part of the LightDirect module family of the VIAVI Multiple Application Platform (MAP), which supports remote VNC, Ethernet, GPIB and local GUI control.
