C-Band Variable Gain Fiber Amplifier (Gain Range 18.5~30.5dB)

Idealphotonics’ MP4700 series is a next generation variable gain fiber amplifier, which is a variable gain fiber amplifier with excellent performance and complete functions on the market today. It adopts the current excellent optical performance, advanced electronic technology, and complete software functions. Excellent transient suppression technology and thermal management control technology enable many complex optical functions to be realized. It is a versatile fiber amplifier commonly used in the market today. The next generation variable gain fiber amplifier consists of a variable gain preamplifier (PA) and a variable gain power amplifier (BA), two-stage amplifier. The gain of the two-stage amplifier can be set independently within a certain range. There is an access connector between the two-stage amplifier, which can be used for mid-stage access, such as optical add/drop multiplexing module (OADM), dispersion compensation module (DCM) and other application optical modules. MP4700 is a version with mid-stage access. The product meets the communication technology requirements of C-Band 44-wavelength or 88-wavelength DWDM system and is widely used in long-distance and ultra-long-distance transmission networks. With its complete functions, it can be used as a line amplifier, preamplifier, power amplifier, and add-drop multiplexing amplifier.

Product features：Next generation variable gain amplifier、 With intermediate access version、 Meet all communication technology requirements of C-Band 44-wavelength or 88-wavelength DWDM system、 Fully integrated electronic control technology using the latest electronic transient control、 Adopt digital control technology that adapts to thermal management、 Intermediate version can be set up as separate preamplifier and power amplifier、 Saturated output power can be selected as 18dBm, 20dBm, 23dBm、 AGC, APC, ACC working modes、 SNMP network management function、 RS232 command interface、 LCD on the front panel provides status monitoring and fault diagnosis, alarm and safety shutdown、 Optional optical monitoring channel OSC Add/Drop、 Carrier-level security, reliability and network management functions、 Low power consumption、 1+1 power backup, supports hot swap、 Excellent performance-price ratio in the industry
