 Metropolitan 
Network providers are more and more looking to Ethernet as a transport and 
service medium.  The primary reason for this is that the vast majority of 
their customers' data begins and ends its life as Ethernet packets.  As a 
result, no expensive protocol conversions are required, no matching of packet to 
cell, no matching of statistically multiplexed data to fixed-bandwidth 
circuits.  However, since Incumbent services (typically frame relay, T1/E1, 
etc.) are well entrenched, Metro Ethernet providers need to offer advanced 
services and a compelling business proposition to lure customers.  Typical 
customers for Metro Ethernet services include small and medium businesses and 
large Enterprises.  Also common are other Service Providers (usually local 
ISP's) that have multiple points-of-presence (POPs) which they need to 
interconnect.  The primary requirements for all these customers are very 
similar, low-cost, high-bandwidth services with security and 
quality-of-service.  Recently, a new service, Virtual Private LAN Services 
(VPLS), has also become a requirement for multi-site customers.  This 
service allows customers to build a local-area network (LAN) using the Metro 
Ethernet network for transport services, but without requiring any complex 
configuration in exchange.  To provide solutions for these varied customer 
needs, the Metro Ethernet network must be flexible and granular, and must scale 
well in performance and cost.
 
 MRV's provides a full Metro Ethernet 
solution, including all aspects of transport, management and connectivity.  
The OptiSwitchT 
product line includes a fully flexible and granular Ethernet switching and 
routing solution from a few ports of 10Mbps Ethernet all the way to hundreds of 
Gigabits of wire-speed IP routing.  The OptiSwitchT Ethernet Circuit 
technology provides complete control over security and bandwidth 
allocation.  Making use of both IEEE 802.1q VLAN as well as MPLS standards, 
the OptiSwitchT can be used to construct a full VPLS network 
providing service to any size customer.  The OptiSwitchT family provides a 
full range of customer connectivity options including copper and 
fiber-optic.  Using MRV's Ethernet-over-VDSL solution, 
customers can even be connected through the standard telephone wires with up to 
15Mbps at distances approaching 8,000 feet.
 
 For the backbone fiber-optic 
transport network, MRV's FiberDriverT product line 
provides a full range of fiber-optic connectivity, including repeaters and 
converters as well as Wave-Division 
Multiplexing (WDM) products to make the most use out of the existing 
fiber.  FiberDriver solutions can be used to create a Metro network that 
spans hundreds of kilometers, and provides a completely managed network 
infrastructure.  MRV's WDM solutions can extend fiber-optic capacity many 
times by combining up to 48 streams of data on the same fiber-optic cable.  
Additionally, with the FiberDriverT fiber-optic transport products, the provider 
can offer other services besides Ethernet if necessary, including SONET/ATM and 
SAN services (via 
FiberChannel, ESCON or FICON).
 
 In some cases, it is difficult or 
impractical to run fiber-optic cabling from building to building, and digging 
trenches can cause long delays.  When this is the case, the MRV TereScopeT line of 
Free-Space Optics (FSO) products provides a quick and easy solution for 
delivering huge bandwidth quickly, at very attractive prices, between 
buildings.  With only line-of-site as a requirement, FSO technology creates a 
high-speed network interconnect (up to Gigabit Ethernet speeds), providing 
exactly the same service as physical fiber-optic cabling but without the 
cable.  FSO technology can be used either to connect POP-to-POP or can be 
used as a customer service delivery method, by placing a TereScope directly at 
the customer location.
 
 In spread-out Metropolitan networks, the network 
management process can be complicated and cumbersome.  MRV provides the MegaVision WebT Network 
Management System, together with the In-ReachT and LX Remote Presence Management 
solutions.  Using MegaVision and In-Reach, the task of operations support 
is centralized and simplified.  Remote Presence technology 
allows the administrator to securely access any part of the network either 
in-band (through the network itself) or out-of-band (through the telephony 
network) for management purposes.  MRV's solution even includes the ability 
to manage the power connections of remote network infrastructure equipment, so 
that an administrator can force an unresponsive machine to power-cycle without 
ever leaving the office.
