LX 15 S 40X0 Full Spectrum Dual Transmitter external modulated
Category : Optopus optical transmitter
The WISI OPTOPUS LX 15 S 4xx0 Transmitter series is part of WISI's CCAP migration solution. Optimized for rack-space savings, it is ideal for transmission of full-spectrum 1.2 GHz channel loads over fiber. Its applications include DOCSIS 3.1 HFC and RFoG.
- Broad frequency range for DOCSIS 3.1
- Wide transmission reach for capacity utilization of centralized headend sites
- Tunable wavelength (optional) enables flexible assignment in DWDM systems
