Parameters

In the 1550nm network coverage system, the 1550nm direct modulation optical transmitter can utilize its overlay technology to achieve narrowband insertion for local IPQAM, CMTS, on-demand and other services, as well as short distance (<20Km) optical transmission or area coverage.

Using low-noise high-quality DFB laser as the light source, with built-in professional APC/ATC control circuit, the performance is stable.
Built in pre distortion circuit design, with excellent CNR, CTB, and CSO index values.
AGC/MGC control can maintain output performance at different RF input levels.
Optional built-in WDM for local insertion services.

●selection of high performance imported DFB laser, equipped with APC/ATC circuit, excellent performance index, output

power stability. ITU-T wavelength selectable.

●has a built-in demultiplexing function and light power adjustable VOA function, to meet customer needs to do 1550nm

light spots.

●advanced pre distortion technology and RF AGC/MGC circuit, effectively improve the nonlinear index, in the designated

RF input range to ensure the stability of the laser modulation system.

●optical transmitter module is equipped with two radio frequency input, port between the amplifier circuit active isolation, with excellent RF isolation

index, makes it easy for users to broadband broadcast service or narrowband business spots of mixed input. The input

terminal is provided with a high pass filter circuit to prevent the electrostatic shock and the low frequency impact.

●light hair module with digital signal compensation function, the user can make compensation settings on the menu, in

order to ensure that the digital channel in broadband applications to increase the time sent module can always be in

the AGC state.

●through the platform optical liquid crystal display to monitor laser power / drift / temperature / current cooling,

redeployment of the input optical power, VOA optical power adjustment of status, RF excitation level, AGC/MGC state,

and various voltage parameters, and can be realized through the optical platform light module of remote network

monitoring.
