HA7300 series is a C+L-Band (1528~1565nm & 1570~1605nm) Pre-amplifier EDFA. According to the gain flatness feature, this series product can be divided into 2 types:

HA7300/SCH: single-channel pre-amplifier, do not fix on gain flatness, suitable for the application of single channel or 1~8 continuous ribbon channels (ITU wavelength).

HA7300/F05: gain-flattened pre-amplifier, realizing gain flatness (F05, ≤±0.5dB) at gain spectrum <1.0dB (Typ.<0.8dB) within whole C+L-Band, as adopting the high-quality GFF and optimization of optical route. Meet requirement of DWDM system C+L-Band pre-amplifier on gain flatness and high output power totally.

HA7300 adopts the world's top class pump laser and America OFS erbium-doped optical fiber. Perfect APC, ACC and ATC control, excellent design in the ventilation and heat-dissipation ensure the long life and high reliable work of pump laser. RS232 and RJ45 offer serial commutation and SNMP network management port. The LCD at the front panel offers the work index of all equipment and warning alarm. The laser will switch off automatically if optical power is missing, which offers security protection for the laser. All the optical port can be installed in the front panel (also can be in the back panel if customers specify).
