Cisco Systems, Inc. TPA-R ONS 15800 TPA-R Transmit Power Amplifier

Cisco TPA-R ONS 15800 Transmit Power Amplifier (Red Band) is a Cisco Systems, Inc. module designed for the ONS 15800 optical transport system. As a transmit power amplifier, it increases the optical power of the signal leaving the transmitter section of the ONS 15800, helping to offset losses in fiber and related components to maintain link performance. The Red Band designation identifies this unit as a specific variant within the TPA-R family for the ONS 15800 platform. This amplifier is part of Cisco’s line of high-capacity optical transport equipment and plays a crucial role in sustaining transmit power within the system’s transmitter chain. In practice, such devices are integrated with supporting transmitter components in Cisco's ONS 15800 architecture.
