the desired optical trip threshold and
actual fiber optical power levels.
1RU rack-mount enclosure with
UL Approved 100-240 Volts AC
power supply.
The Force Model 5615 Optical A/B Switch provides an automatic fiber switching function for redundant protection of
optical signals. Each fiber’s optical signal power level is monitored, as is an adjustable optical trip threshold for each
channel. If the primary fiber’s optical signal power level falls below the desired optical trip threshold, the unit
automatically switches to the secondary fiber, thus eliminating the need for intervention of a system operator. Returning
to the primary fiber is automatic when the signal on fiber 1 is restored. The disabled path selection switch in auto mode
prevents path 2 from being set at the primary fiber. Additional flexibility is added via forced manual channel selection. This
feature expands the functionality of the redundant unit. For example, the user could not provide unique signals to each
channel and switch between each as desired. The Model 5615 adds stability to many system applications, such as WDM
networks, high-speed communications, and long-haul telecommunications.
