A very Different EYDFA (High Power EDFA)
What is the Erbium Yterbium Doped Fiber Amplifier (EYDFA) ?
EYDFA is based on the EDFA structure and includes a Yterbium doped fiber amplifier module, which is used to boost fiber signal to a more intensive optical network. EYDFA is primarily used in high power optical amplifiers with total output power ranging from 25 to 42dBm (or higher).
PL2000H Series
It has low noise and high linearity performance to meet the most stringent CATV and FTTx application requirements. It offers a flexible and low-cost solution for wide-area distribution networks. The PL2000H is the first unit in the CATV industry that comes with a touchscreen LCD and back reflection function.
PL2000H Series EYDFA
Main Features
Output Optical Power
Based on the optical power included 25~40dBm before splitter.It is available to make special modifications to a specified output power up to 43dBm before splitter. This optical amplifier has built-in optical power splitter for providing up to 128 output ports. Standardis at 1, 2, 4, 8, 16, 32 or 64 output power port.
Control Modes
Three optical output power control modes:
APC (Automatic Power Control): Output Optical Power Level Stabilization
ACC (Automatic Current Control): Pump Current Level Stabilization
AGC (Automatic Gain Control): Optical Gain Level Stabilization
Measurement
Equipped with standard measures of input power and back reflection optical power and reflected power meter within wide dynamic range. Measurement of reverse reflection is useful function to monitor networks and to configure optimal settings exploitation.
Optical Switch & xPON
Equipped with automatic redundant input port according to customer request.Optical power level at each of the two input ports is measured independently, allowing you to instantly switch from the primary input port to the backup input port, and also available with GPON, XGS-PON Pass through for PON networks.
Management
All PL2000H series optical amplifiers have a built-in Web server, which can be reviewed by any of the widely used web browser. Controlling and monitoring of the amplifier is used by the menu of interactive Web pages. On-demand monitoring of the amplifier can also be accessed by our SNMP Manager.
Mechanical
All is in a standard 2U (1U and 3U), 19 “, equipped with 3 reliable cooling fans operating in parallel with microprocessor overheating protection. It is capable of working with temperature up to 50°c, and, if necessary, up to 60°c is optional. Standard power operates on AC 90~264V with high efficiency and high reliability.
