If you’re not going all Fiber-to-the-Home (FTTH), you still have quite a few options for wringing more bandwidth out of your broadband network. I’m starting a tally of techniques. What have I missed?
- Switched Digital Video – Video streams are only switched on when requested by a subscriber.
- Channel Bonding – Part of the DOCSIS 3.0 spec, the technique bonds channels together to deliver more capacity to a home cable modem.
- Analog Reclamation – “Cable is going to unleash a tsunami of bandwidth in 2009 when analog is retired,” Zachary Investment’s Comack said.
- MPEG-4 Compression – Not exactly bandwidth expansion, compression minimizes the amount of bandwidth that streaming video requires.
- Cable PON (fiber deep) – Lays the groundwork (literally) for making use of FTTH in the future
- E-CWDM – This is a Motorola twist on CWDM: Enhanced Coarse Wavelength Division Multiplexing. It segments a single fiber optic connection to serve three, four or five discrete areas at distances of up to 25 km between a hub and a fiber node.
- Decoupled CMTS Modules – Separates upstream broadband traffic from downstream traffic. (Detailed example here)
- Spectrum Management/Monitoring – Technology for monitoring traffic and making automatic adjustments improves overall network performance.
