The first wave of Motorola press releases for SCTE Cable-Tec Expo has hit the wires. Among them are announcements of new RF technology, new fiber-deep and CablePON solutions, and Motorola’s first major RF-over-Glass (RFOG) customer deployment. I’ll try to cover all of the news in some detail in the coming days, but for the moment I want to focus on Motorola’s fourth announcement, the launch of the RX48 decoupled upstream module.
The RX48 card is the upstream twin to Motorola’s popular TX32 downstream module, and it works in much the same way. By replacing an old 2×8 card in a Motorola integrated-CMTS (I-CMTS) chassis (see photo right), operators go from having eight upstream ports to 48. Those 48 ports are densely packed together, and they raise upstream capacity to nearly 1.5 gigabits per second per card. That increased capacity can be used to raise average available bandwidth to subscribers, or it can be used to support upstream channel bonding for higher peak upstream speeds. Both features are important. Increased average available bandwidth is critical because more people are engaging with two-way Web applications, and increased peak bandwidth is important because larger data uploads are taking place with consumer HD video and Internet-based file back-up systems.
Upstream bandwidth is looking to be a hot topic at this week’s SCTE show, and I plan to get some on-site time with the RX48 demo. For other advance reading, check out one of my earlier posts on S-CDMA upstream conditioning technology. Motorola’s S-CDMA solution cleans up low-spectrum frequencies to increase upstream capacity by around 50%. It’s makes a nice complement to the new RX48 module.

Does this have anything that will effect the future of the speeds for clear wimax services? I know this is a shot in the dark question…
Not really. Though I suppose it could affect backhaul for WiMAX. I’ll see if I can find out anything specific.
Thanks Mari.
I am really lovin this wimax system
