Optical Transmission
EDFA Optical Amplifier

VCL-9009 is a high stability output power EDFA (Erbium Doped Fiber Amplifier) which may be used to provide an optical signal gain of up to 20dBm. The stability pump laser and unique ATC (automatic temperature control) and AGC (automatic gain control) circuits incorporated in the unit ensures excellent optical characteristics and high stability that allow the unit to operate over a wide temperature range and harsh environmental conditions. The high stability and high precision OAM (Operation and Management) interface uses a strong password control and provide secure access and advanced monitoring capabilities. The unit can be securely monitored and managed remotely using SSH and SNMPv3.

Advanced GFF (gain flattening filter) with excellent optical path design ensure a linear, low noise optical output.

The optical circuit is designed especially for digital optical fiber communication system including:

1. Lower noise figure
2. The high output booster and high sensitivity pre-amplifier improve the system loss budget.
3. Broad input power range and output power is user adjustable.

VCL-9009, provides a highly secure management interface which can also be incorporated in any third-party network management system which uses standard SSH and SNMPv3 communication protocols. The OAM (Operation and Management) include 10/100BaseT Ethernet, USB and Serial RS-232 interfaces. MIB file is also provided with the equipment for integration with third-party NMS.

Access and Control:

• Secure, password-controlled access with password strength monitoring
• SNMPv3 management protocol for management and monitoring
• Time-stamped alarm and event logging
• NTP and IEEE 1588v2 PTP clock synchronization options for accurate time-stamping of all alarms and events
• NTP time synchronization option to synchronize time-stamp with NTP Server
