For efficient transport of commercial services (as well as residential services) from the d-hub to the headend or primary ...

... subscribers. Of course, it makes no sense to transport in both formats over the metro network. It makes even less sense to add capacity to legacy ASI over SONET/SDH platforms that will eventually run out of steam. You need a more scalable solution to cost-effectively transport and replicate an ever ...

... consumed many fiber strands between the headend and d-hubs as well as between headends in a region. This has occurred primarily because each new DVB-ASI, SONET, ATM or POS ring built to increase network capacity required its own dedicated fiber or fiber pair. As optical rings run out of fiber, you need ...

... different headends in a region. This is primarily because each new ring built to handle the increasing capacity demand of existing protocols such as ASI-based broadcast video, SONET/SDH, ATM, RPR and POS required its own dedicated fiber or fiber pair. Eventually, operators found themselves in fiber ...
