How Metro Media Fiber uses Nortel's Metro DWDM Platform - from the same article
"Now, customers have the option to lease what MFN calls "managed networks."
The customer still has complete control of what goes over its own network, and
still pays for capacity on a per fiber, or per wavelength, unmetered basis, but
Metromedia will now install and manage the optical networking equipment that
a particular customer chooses. Currently, MFN offers three types of solutions
within this model: Gigabit Ethernet; SONET; and Wave Division Multiplexing.
Different customers will select different technologies, according to the
applications they plan to support, but Berry says that the WDM offering, called
"Wave Channel," has recently become the most popular. The reason, he
explains, is that with WDM the customer essentially doesn't have to choose
between applications: "Wave Channel allows customers to run any protocol,
any application, and even multiple protocols or applications on a single pair of
fibers."
Using Nortel Networks' OPTera Metro DWDM platform, MFN can multiplex up
to 32 OC-48 channels onto a single fiber pair. Customers can pay per channel
for the capacity they need, but still get a whole, unshared piece of fiber. Within
a fiber, one wavelength might be used to carry Gigabit Ethernet traffic, while
another might be linked to SONET equipment, with still another receiving data
directly from an IP router. Berry says that a MFN customer would pay roughly
the same for a 2.5 Gbps wavelength as they would for a 45 Mbps pipe from a
carrier today.
