DWDV-1000|Zhejiang GT Lasers Tech. Co., Ltd.

GT LASERS DWDV-1000 series, integrate of DWDM and Electronically controlled variable optical attenuator (VOA) in 1RU or 3U chassis, each channel of DWDM has one high-resolution electronically controlled variable optical attenuator, adjust the optical power. Compact and simple device structure reducing the number of connections between devices, improve the system parameters and device reliability. It can be easily and flexibly used in DWDM system inter-channel power adjustment and automatic balance, optical add-drop multiplexing (OADM).

Each channel of DWDV has output optical power monitor, detection accuracy≤±0.1dB. Automatic power control mode setting available. According to the different application of the network, DWDV-1000 has MU, DE, DM, AD four different optical ways optional. RS232 and RJ45 are the communication and SNMP interface, LCD in the front panel supply all the operate parameters and fault alarm. All the optic ports can be installed in the front panel or back panel.

DWDV-1000: 100GHz channel spacing.

DWDV-2000: 200GHz channel spacing (Optional).
