Product description
Huatai HWA4200 series, is designed for C-Band 44 waves or 88 waves DWDM system design Line 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.
HWA4200 is mainly installed in middle of transmission line, replacing the traditional relay, to compensate the optical power loss in the line and extend the optical signal transmission distance.
HWA4200 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.
HWA4200 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).
HWA4200 enhanced version, for 44 wave DWDM systems, providing a flexible, high-performance, low-cost networking applications.
