• 1550nm Erbium Doped Fiber Amplifier (standard) adopts 980nm or 1480nm high linearity, optical isolation, the DFB, thermoelectric cooling DFB laser produced by JDS-U, Fujitsu, Nortel, Lucent, Fitel and other world-renowned semiconductor companies as the pumping source. 
• In the interior of the machine is equipped with the output optical power stability circuit and laser thermoelectric cooling device, temperature stability control circuit to ensure optimal machine performance and long-life laser stability. 
• The microprocessor software monitor the laser’s working state, the VFD screen displays the operating parameters. Once the laser operating parameters deviate from the permissible range set by the software, micro- processing will automatically turn off laser power, red light goes on to warn, digital panel prompts cause of troubles

Features:

• High quality: The former-class pump commonly uses 980nm, after-class pump use 1480nm, power is legitimately optimized by software to minimize the NF of the EDFA, could be comparable with the so-called low-power optical amplifier. It can make the system to obtain superior CNR.

Reliability:

• The 19 "1U standard rack, built-in high-performance switching power supply, it can work at 85~265Vac City Network Voltage, As well as an optional DC48V power supply (reservations required); Chassis cooling automatic  temperature control. Mechanical cooler (heat sink) on one side of the chassis helps to make heat dispersion thus to protect the pump laser

Intuitive:

• The laser is the most expensive machine components, machine equipped with microprocessor monitors the working state of the laser, and the panel LCD window displays the operating parameters.

Network Type:

• Select all piece status monitoring transponder guarantee  to meet the national standard and be compatible with the SCTE HMS standard, it enable network management monitoring capabilities.
