AC7700 Digital transmitter
AC7700 products are digital CWDM DFB laser transmitters for the return path applications of the AC9000 node. The module has two return path inputs and one optical wavelength carries two RF return paths.
Features at a glance:
- Two RF return paths on one optical carrier
- High optical output power
- Long link span
- Low power consumption
