YTF5238HB-II series optical workstation
The YTF5238HB series optical workstations are two-way optical nodes developed for the FTTB topology of cable TV HFC networks specifically. It’s easy to configure with various functional modules. Its RF main board is designed to reach 1000MHz bandwidth. Four independent GaAs gain blocks can provide high quality signal to cover 400 to 500 HPs. RFOG module can be added in return path according to user’s requirement.
