The CEFA-C-BD amplifiers are real bidirectional fibre amplifiers, which means that the two 1550nm signals are travelling in the same optical fibre. This optical design is therefore interesting for applications requiring the same propagation time in both directions.
The CEFA-C-BD series are available in 1U turnkey benchtops and can integrate one or two BD amplifiers in the same 1U rack. The amplifiers can be controlled via the front panel or remotely via serial USB and ethernet ports.
