HDO761发射机
The HDO761 downstream dual transmitter supports frequencies up to 1218 MHz and is available with an output power of 10 dBm. HDO761 is a 1550 nm DWDM transmitter for long distances. It supports broadcast and narrowcast and services in digital format.
Features at a glance:
- DOCSIS 3.1兼容1.2 GHz带宽
- ITU wavelengths in 100 GHz grid
- Electrical dispersion compensator provides a good CSO performance at longer transmission distances
- Standardised input and test point levels
- Low power consumption and high performance
- Four identical inputs with individual level and slope adjustments
- High isolation between inputs
- Unused 2nd inputs can be switched off for power saving and noise reduction
- Drive amplifier can be set to power save mode in narrowcast load conditions
- Integrated input amplifiers and laser driver amplifiers
- Automatic power control providing constant total OMI as a standard feature
- Optional integrated DWDM filtering to combine two different ITU wavelengths into one common output and enabling optical daisy chaining of multiple HDO761 transmitters
- Fibre connectors can be located at the rear or at the front panel
- Small form factor family, 2 RU height
- Local and remote software control of all adjustments
- Forced cooling through the unit
