8 Port EDFA with WDM

Qualfiber series 8port EDFA is a low noise, high performance, FTTP high power, multi-ports optical amplifier with gain spectrum band within 1540~1563nm. Each output port for optical amplifier has built-in well-performed WDM. Every external up-link optical port of optical amplifier can connect with OLT PON port very conveniently. Each 1550nm (CATV)’s output optical port multiplex 1310/1490n’s data stream, in order to reduce the quantity of the component and improve the index and reliability of the system.

Product Detail

Qualfiber uses the world’s top brand pump lasers and US OFS active fiber. Perfect APC, ACC, ATC control and good ventilation and heat dissipation design ensure the long life and high reliability of PUMP Laser. RJ45 provides the SNMP network management interface. The full dot-matrix LCD on the front panel provides the operating parameters and alarms of the whole machine. Light is lost and the laser is automatically turned off, providing laser safety protection. All optical ports can be installed on the front panel or can be installed on the rear panel. The product’s high quality, high reliability and excellent cost performance, carrier-grade security reliability and network management are ideal choices for system integrators and system operators.
