Wide-Band Variable Optical Attenuator and Per-Band Optical Equalizer

Modules

The WB-VOA (wide-band variable optical attenuator) and PB-OE (per-band power equalizer) modules

are half-width modules that allow the ONS 15530 to extend the internodal and ring circumference

distances and number of nodes supported for point-to-point, hub ring, and mesh ring networks by

equalizing power levels.

The WB-VOA module and the PB-OE module are available in single and dual band versions. These

modules are installed into a carrier motherboard. This motherboard is installed into and operates on the

Cisco ONS 15530 chassis. The carrier motherboard can be installed in slots 1 to 4 or 7 to 10. All optical

connectors are located on the front panel and the connectors are angled.

Figure 1-17 and Figure 1-18 show the single and dual versions of the WB-VOA module. Figure 1-19 and

Figure 1-20 show the single-band and dual-band versions of the PB-OE module.
