The good news:
Gigabit Ethernet, GigE, is really fast. It’s great for really fast routers, remote data storage, lots of HDTV signals, medical imaging, commerce and life in general.

The bad news:
If a GigE fails, you could be the center of attention. People you’ve never met will know “your network” isn’t working.

___________________________________________________________________________________________________

GigE requires fiber to support connections longer than a few feet. While use of fiber is common, growing GigE applications can mean you’ll run out of fiber. Adding more fiber is expensive.

If fiber connects two points in your network and your network fails, it can be tough to figure out if the failure was caused by a cut fiber, a loss of power or an equipment failure. “Rolling trucks” is an expensive and time consuming way to figure out what’s gone wrong. It's possible to install GigE routers at far-end terminations to help determine where a problem has occurred, but you can often buy a truck for the price of some of these routers. Okay -- maybe a used truck -- but GigE routers are expensive, and they're complicated.

In fact, GigE equipment is expensive in general.  For example, a SONET OC-48 (2,400,000,000 bits/second) circuit can only support 2 GigE signals, so if you want the luxury of standard, robust SONET technology to carry critical GigE signals, costs can be high and setting up circuits requires a lot of training and configuration. Power for these systems is expensive too.

Back to the good news:

Pulsecom's G2 family of OC-48-to-GigE multiplexers can overcome remote monitoring, limited fiber and cost issues that have challenged wide-spread GigE adoption.

G2s leverage existing dark fiber, lit fiber or higher-order SONET multiplexers to eliminate the cost and delays associated with installing more optical facilities. With two full-rate GigEs per G2 and available integrated DWDM OC48 transport, dozens of GigE circuits can be carried over a fiber pair so you can often avoid the high price and installation delays associated with DMDW systems too. G2 installation? Like other Pulsecom products using our patent-pending "Optionless SONET" technology, it's out of the box and into service in just about 15 minutes. That includes mounting, powering, connection to fiber cables and watching the lights turn green. There isn't any provisioning -- just select "Drop or Continue" for each of the two GigEs.

Major ILECs are already using G2s to extend their GigE networks, isolate problems and eliminate unnecessary truck rolls.

And, we think you won't find a less expensive OC48-toGigE multiplexer.

Finally, the pièce de résistance, you can start with a Pulsecom OC3 to quad DS1 card, migrate to a DS3 by replacing the card with an OC3 to DS3 unit and then upgrade your network to GigE by replacing the DS3 card with a G2 to ramp your speed to GigE. That’s DS1 to GigE scalability in the same 7” x7” x 2” wall or rack mounted shelf. Go figure!
