Kingray KOA EDFA Optical Amplifier: 4/8/16/32 Port, 1550nm w/CWDM, +15.5dBm p/Port, 19″

The KOA 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. Each 1550nm (CATV)’s output optical port can optically multiplex with corresponding 1310/1490n’s carrier OLT PON input data stream to reduce the number of components and improve the reliability of the system.

The KOA Series optical amplifiers can be made to be compatible with any FTTx PON Technology. The range offers a flexible and low-cost solution for multi service network integration and fibre to the home.

The KOA Series has 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 KOA Series 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.

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

KOA optical amplifier uses a 19” 1RU chassis, for the 4, 8 and 16 port versions. The 32 port model is in a 19” 2RU chassis.

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