Interface Naming Conventions
Voafilterin Subinterfaces
The voafilterin subinterface identifies the attenuator within the PB-OE module.
The naming convention for the voafilterin interface on a PB-OE module is as follows:
voafilterin slot/subcard/port.subinterface
Single band PB-OE modules have one voafilterin subinterface. Dual band PB-OE modules have two
voafilterin subinterfaces.
Voafilterout Interfaces
The voafilterout interface sends the DWDM signal to the EDFA (erbium-doped fiber amplifier) or the
next node in the network topology.
The naming convention for the voafilterout interface on a PB-OE module is as follows:
voafilterout slot/subcard/port
Voabypassout Interfaces
The voabypassout interface carries that portion of the signal not attenuated by the PB-OE module. This
interface connects to another VOA module input interface (either a voain interface or a voafilterin
interface) where the signal is further attenuated.
The naming convention for the voabypassout interface on a PB-OE module is as follows:
voabypassout slot/subcard/port
Voabypassin Interfaces
The voabypassin interface carries that portion of the signal attenuated on other modules. This interface
connects to another VOA module output interface (either a voaout interface or a voafilterout interface)
where the signal was attenuated.
The naming convention for the voabypassin interface on a PB-OE module is as fo l lows:
voabypassin slot/subcard/port
