General Information and Specifications

General Information

This user's manual for the SKB Series Fiberoptic Switch Module contains complete operating
instructions.
The SKB modular 1xN controllable switch controls up to four 1xN optical switches, with
configurations up to 100 channels (Figure 1). Small and rugged, the switch is designed to be
used in embedded applications. It is available in single-mode (SM) and multimode (MM)
versions. It has several features that reduce installation and support efforts. The switch offers
low insertion loss and is independent of data format and direction (bidirectional).
The standard single-pole configuration consists of a single-common port that can be aligned to
any one of 26 ports. In electrical terms, the SKB switch is a single-pole, 26-throw switch. The
switching mechanism implements collimating lenses that eliminate the problems associated
with modal noise and provide low insertion loss and high repeatability.
With use of an adapter cable assembly (user supplied), the switch is backward compatible with
the SK Series Fiberoptic Switch Module and the SP Series Fiberoptic Switch Module.
The switch can operate in an enhanced command mode that provides the capability of readable
switch parameters.
The optics can be internally connected to provide custom solutions at the customer's request.

Configurations

The SKB switch is offered in a standard chassis with standard software that controls numerous
configurations. Examples, shown in Figure 2, include
•
A single switch with 1xN configuration for N up to 100
•
Up to four 1xN switches with a total channel count of up to 100 (for example, four 1x25
switches, two 1x50 switches, and so on)
•
Up to two MxN blocking switches for a total M+N channel count of 100 (for example, two
25x25 switches, one 50x50 switch, and so on)
•
1xN switches plus relay switches and passive devices, such as couplers (for example, two
1x25 stepper motor switches with two relay switches and couplers)
