KOA4PX-15
Where to Buy

KOA X Series is a low noise, high performance, fibre to the premises (FTTP) high power, multi-ports optical amplifier with a gain spectrum bandwidth within 1540~1563nm range. The output port for the optical amplifier has a built-in Coarse Wavelength Division Multiplexer to enable multiplexing with corresponding input ports connecting to a carrier OLT PON port should this be required. Each 1550nm (CATV)’s output optical port can optically multiplex with corresponding 1270/1310/1490/1577nm carrier OLT PON (GPON & XGSPON) input data stream to reduce the number of components and improve the reliability of the system.

The optical amplifiers have a very low noise figure and the units adopt twin-stage amplification. The pre-amplifier uses low noise EDFA, with its output feeding into the high-power Erbium Ytterbium Doped Fibre Amplifier (EYDFA). The noise figure of optical amplifiers are ≤5.5dB, with input optical power Pin=0dBm.

The optical amplifiers uses a high-quality Pump Laser, Auto Output Power stability Control (APC), Automatic Current Control (ACC), and Auto Temperature Control (ATC), combined with excellent ventilation and heat-dissipation from the unit to ensure long life and achieve a highly reliable pump laser performance. The LCD at the front panel provides a means of quickly checking the key parameters for the equipment and any warning alarms. The pump laser will switch off automatically if optical power is disconnected, which offers protection for the pump laser.

The optical amplifier supports dual power supply, 1+1 backup and is powered by AC power.

The optical amplifier uses a 19” 1RU chassis, for the 4, 8 and 16 port versions.

The equipment is managed via the SNMP network management port which is a RJ45 interface.
