The BTEA Series are 1550 nm Erbium Doped Fiber Amplifiers (EDFA) engineered to meet the requirements for distribution of CATV video and data signals in FTTH/FTTP and HFC systems. Models are available with 1, 2 or 4 outputs with either 16 dBm or 19 dBm optical output per port.
This rugged, low-profile, high-efficiency EDFA design utilizes powerful and reliable pump amplifiers in a two-stage design with interstage isolators. The unit's wide optical input range accepts a single optical input and provides a total composite/saturated output power of up to 400mW/26 dBm (19 dBm, 4 output model). As a matter of convenience and safety, this high output is further limited by dividing the unit's power into individual optical output ports via an internal low loss coupler, which ultimately provides 1, 2, or4 optical output ports of +16 dBm or +19dBm depending upon model.
