CATV Inline Multi point Broadcasting EDFA

LA54 series is a high power multi-ports optical amplifier with gain spectrum band within 1540~1563nm. It is designed for the application of CATV or 1~8 continuous banding channel (ITU wavelength). It offers a flexible
and low-cost solution for CATV large area coverage of metropolises and medium-sized cities.
LA54 has extremely low noise figure, the entire unit adopts twin-stage amplification, and the pre-amplifier adopts low noise EDFA, output cascade adopts high power EYDFA. When input optical power Pin=0dBm, the noise figure of unit is: Typ ≤4.5dB, Max ≤5.5dB Unlike other kind of product which need high optical power input to maintain lower noise figure.
LA54 LCD at the front panel offers the work index of all equipment and warning alarms. The laser will switch off automatically if optical power is missing, which offers security protection for the laser. Serial commutation (RS232) and SNMP network management is available as an option. All the optical port of optical amplifier can be installed in the front panel or back panel.

LA54A:1RU rack, total output power>5000mW, offers at most 32 optical outputs
LA54B:2RU rack, total output power>13000mW, offers at most 128 optical outputs
