Metro Network Trends
• Enterprise bandwidth requirements continue to grow exponentially
• Growing number of high-rate data interfaces, according to industry
studies* [OC 48 equivalent bandwidth]
• year 2000 = 8000 OC48’s
• year 2005 = 100,000+ OC48’s
– Need to support different protocols:
– Fast Ethernet, Gigabit Ethernet, ESCON, FICON, Fibre
Channel, Video, etc. (Future 10 Gbps Ethernet)
• More timely delivery of bandwidth; scalability is critical

Single Mode Fiber
 Thin core with continuous light waveguide
 No room for light to bounce in core

Evolution of Optical
Electronics
Wave Division Multiplexing (WDM) - A technology that allows
multiple wavelengths to be multiplexed over a single strand of
fiber. Comes in various forms including Dense and Wide
depending on the number of wavelengths involved.

Dense Wave Division Multiplexing
“Kicks it up a notch”
Single Mode Fiber
•
The cutting edge of fiber optics
• Light contains many colors
• Each color carries a separate channel
• Example with 64 colors
~ 10 Gbps per color
~ 640 Gbps per Single Mode Fiber

Data Transfer Rate
•
Metric Code
When used to describe Data Transfer Rate, bits/bytes are calculated as in the
metric system:
For Example:
1 bit (b) = 0 or 1 = one binary digit
1 kilobit (kb / Kb / K) = 10^3 bits = 1,000 bits
1 Megabit (Mb) = 10^6 bits = 1,000,000 bits
1 Gigabit (Gb) = 10^9 bits = 1,000,000,000 bits
1 Terabit (Tb) = 10^12 bits = 1,000,000,000,000 bits
1 Petabit (Pb) = 10^15 bits = 1,000,000,000,000,000 bits
1 Exabit (Eb) = 10^18 bits = 1,000,000,000,000,000,000 bits
1 Zettabit (Zb) = 10^21 bits = 1,000,000,000,000,000,000,000 bits
1 Yottabit (Yb) = 10^24 bits = 1,000,000,000,000,000,000,000,000 bits
1 Google = 10^100
1 GooglePlex = 10^[10^100]
•

•
•
Note: Kilobits per second is usually shortened to kbps or Kbps. Although technically speaking, the term
11
kilobit should have a lowercase initial letter, it has become common to capitalize it in abbreviation (e.g.
"56 Kbps" or "56K"). The simple "K" might seem ambiguous but, in the context of data transfer, it can
be assumed that the measurement is in bits rather than bytes unless indicated otherwise.
The Ethernet Evolution-Need for
Speed
• LANs are the most important part of data
networking.
• Common vehicle for data to pass over LANs has
been the Ethernet Protocol.
• 10 Mbps was sufficient in the 90’s
• Progression to Fast Ethernet (100 Mbps)
• Replaced by Gigabit Ethernet (1000 Mbps)

What is FibreMAN?
•
FibreMAN (Fibre Channel Metropolitan Area Network) is based on the Fibre Channel protocol.
The FibreMAN product offering is a fiber based point-to-point transport service. This service is
used to connect customer provided Fibre Channel switches or routers from one customer location to
another at a 1 Gbps or 2 Gbps line rate. The Fibre Channel protocol is an effective transport
medium for storage area networks (SANs).
Applications
• Corporate information is a key competitive factor, and FibreMAN enhances IT and storage
departments' ability to access and protect it more efficiently. FibreMAN will provide organizations
a reliable and scalable way to extend the connectivity between customer sites to enable storage
connectivity between servers.
• FibreMAN and GigaMAN® make a great bundle! An ideal candidate are those customers that
have existing GigaMAN service to see if they need a Fibre Channel circuit between those same two
locations.
• FibreMAN is ideal for these applications:
• Fibre Channel is the #1 application for storage:
• Network based storage
• Storage backup systems and recovery – for improved disaster tolerance solutions
• Connectivity within server clusters
• Connectivity within storage arrays
• Connectivity for access to large databases and data warehouses
• Connectivity from internet data centers and/or web hosting data centers to corporate data centers or
other corporate offices
• Storage transport for imaging applications
16
Multi-Service Optical Network
(MON) Value Proposition
• For customers who have requirements for protocol
transparent bandwidth for typically more than 3 Gbps
between two or more customer sites and/or Central
Offices, MON is a fully managed network solution that is
flexible and scalable utilizing DWDM technology that
delivers high bandwidth services in their native format.
• Unlike private fiber/dark fiber solutions, our service is
fully managed by highly trained technicians via a highquality network and is available in all SBC regions.
