Description

Overview:
The EY-doped fiber amplifier is a high power optical amplifier. It offers a highly reliable, flexible and low-cost solution for CATV large area coverage of metropolises and medium sized cities, that are high density home pass, especially for FTTH application.

• Feature:
• High output power, E-Y co-doped
• Warm backup, on-line standby, auto redundancy
• Support ITU channels banding
• Low optical input power, Adjustable output optical power -3dB
• APC / ATC circuit design, built-in high-power optical isolator, mainly used for fiber access network of EPON architecture
• Single/dual input for choice, built in optical switch for dual input, the switching  power can be set by the button in the front panel or by web snmp.
•  Output adjustable by buttons in the front panel or web snmp, the range  is +0.5dBm～-4.0dBm
• Max multi 32 ports, with built in 1310/1490/1550WDM,max total output 37 dBm
• Standard RJ 45 port for remote control, we can provide output contract and web manager for choice, and also plug-in snmp hardware can be reserved for update.
• With laser key to turn on/off the laser.
• With RF test function.
• Adopts  JDSU or Oclaro Pump laser
• Led displays the working condition of the machine
• Dual power hot plug power supply for choice, 90V～250V AC or -48V DC
