Product Description

 

 

 

Product Description:

WT-1550-DM intelligent directly modulated optical transmitter is mainly used in 1550nm optical fiber transmission system. Adopt advanced electronic dispersion compensation technology, accurately compensate according to the actual transmission distance by 1km stepping. The maximum compensated distance up to 50km.
WT-1550-DM intelligent directly modulated optical transmitter is the most important equipment to construct the CATV network. It mainly used for the value-added services of TV image signal, digital television signal, telephone voice signal and data (or compressed data) signal. By built-in WDM, multiplex the inter-cut optical signal and the main optical signal then output. After setting required optical difference, the perfect adjustable optical attenuation function can automatic control the inserted optical signal according to the main optical signal, realize inter-cut system full automatic adjustment. Provide high quality low cost solution for all-optical relay 1550 optical fiber CATV system, and local value-added services inter-cut.

 

 

Characteristics:

      1. Patent pre-distortion circuit.

      2. The optical fiber distance is adjustable according to the actual use condition by 1km stepping.

      3. WT-1550-DM: Built-in WDM, multiplex the inserted optical signal and the main optical signal then output.

      4. WT-1550-DM : Built-in WDM and adjustable attenuator.
