Optical Bidirectional Amplifier
Optical Bidirectional Amplifier for
fiber time and frequency distribution system
Fiber-optic systems used to transfer or distribute metrological signals (optical frequency, radio frequency or time) require symmetry for optical signals propagating in both, forward and backward, directions. When the attenuation of the fiber connecting the endpoints of the link exceeds dome limit signal regeneration starts to be necessary. The most versatile and simple option is to employ an optical amplifier. The OBA-3 optical bidirectional amplifiers are designed especially to extend the operation distance on the links showing more than 25 dB of attenuation (i.e. the distance exceeding about 50 to 100 km).
The OBA-3 amplifiers are fully compatible with the OSTT series of time and frequency distribution system and optical frequency distribution systems.
