Product description
Huatai HWA4300 series, is designed for C-Band 44 waves or 88 waves DWDM system design Pre-Amplifier gain flatness. Products using the most excellent optical performance, the most advanced electronic control technology and comprehensive software features, has a wide operating wavelength range, Low noise, excellent gain flatness characteristics and transient characteristics.
HWA4300 is mainly installed in the front of receiver, used for improving sensitivity of the receiver and extending the signal transmission distance.
HWA4300 the world's top brands of pump lasers, advanced electronic circuit design and low power consumption, which greatly reduces the overall thermal power, to ensure long life and high reliability PUMP Laser work. Front panel LCD, LED offers the work parameters and alarms. RS232 and RJ45 provides serial communications and SNMP network management interface. Optical loss, laser automatically shut down, provides laser safety protection.
HWA4300 has two kinds of function versions are available:
1. Standard version: provides a fixed gain control mode (FGA), the pump current control mode (ACC)
2. Enhanced version: In addition to the standard version with the control functions, increasing the variable gain control mode (VGA, AGC), Variable output power control mode (VPA, APC).
HWA4300 enhanced version, for 44 wave DWDM systems, providing a flexible, high-performance, low-cost networking applications.
