Connet MARS series L-band optical fiber amplifier is integrated with high power and high property multi-mode pumps, plus with double cladding fiber amplifying technology and the optimized optical structure design to realize output power up to 5W. It has built-in laser current driver, high accuracy ATC&ACC (APC) driver electronics controller and excellent LCD display interface in turn-key benchtop package to realize the high stable output. 

The output power is continuously tunable and can be precisely controlled. The output power can be set per request via easy operation. The MARS series L-band Er-doped fiber amplifiers have two types of packages for option in benchtop and module-level. All systems can communicate with computer through the equipped RS232 interface.

The MARS series L-band Er-doped fiber amplifiers are also designed for amplifying the single-mode or the polarization-maintaining signal of the single wavelength optical transmission system. The maximum output power can be up to 23dBm. 

Through the extensive experience of handling the double cladding fiber, Connet conducts the proper optimal optical structure design to the high power fiber amplifiers to achieve the high efficiency output. The high-speed response protection circuit monitor the power of input and output signal automatically so that it can cut down the operation of the high power pump in case of the falling off of the input signal to ensure the safety of the whole system.
