Caute. Ostali nam tieto zariadenia z nevydarenej DVB-T telky.
Fungovalo to perfektne, ale nenasli sme na to zakaznika, nakoniec si vsetci aj tak vybrali IPTV...
1) EDFA 4x 21dBm 1550nm s CWDM (IN GPON 1490/1310nm, OUT 1490/1310nm a 1550nm)
2) Celeste Luminato
- 2x - 2/4 COFDM modulators, upconversion, DVB Prosessing
- 2x - LCM-B option: Multiplexing (multiple IP inputs per modulator), 1 License per HW module
- 2x - LCM-B option: EIT multiplexing, 1 License per HW module
3) Optický vysielač 1550nm, 10dBm
4) 20x ISCOM HT803-R-E - tych je tusim viac...
Cele to funguje tak ze do GEponu, Gponu zamiesana vlnovu dlzku kde je DVB-T nasledne na ONU je rf port na ktorom si vytiahnete TV na koaxi..
Cenu navrhnite. |
