Evolution of Fiber

• Thin core with continuous light waveguide
• No room for light to bounce in core
• Most commonly used mode
• Currently 8.3 - 9.5 um core size
• millionth of a meter (3.28ft)
• 1300 nm wavelength billionth of a meter

7
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.

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) 103 bits 1,000 bits 1 Megabit
  (Mb) 106 bits 1,000,000 bits 1 Gigabit (Gb)
  109 bits 1,000,000,000 bits1 Terabit (Tb)
  1012 bits 1,000,000,000,000 bits1 Petabit
  (Pb) 1015 bits 1,000,000,000,000,000 bits1
  Exabit (Eb) 1018 bits 1,000,000,000,000,000,0
  00 bits1 Zettabit (Zb) 1021 bits
  1,000,000,000,000,000,000,000 bits1 Yottabit
  (Yb) 1024 bits 1,000,000,000,000,000,000,000,
  000 bits
• 1 Google 10100
• 1 GooglePlex 1010100Note Kilobits per
  second is usually shortened to kbps or Kbps.
  Although technically speaking, the term 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.

12
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 90s
• Progression to Fast Ethernet (100 Mbps)
• Replaced by Gigabit Ethernet (1000 Mbps)

10 Mbps
13
GigaMAN is

• GigaMAN Service is used to connect two customer
  locations at the rate of 1 Gigabit per second. (
  OR 1 billion bits per second)
• 22 X the speed of DS3!
• 647 X the speed of DS1!

14
DecaMANSM is

• SBC Optical transport service used to connect two
  customer locations at the rate of 10 Gigabits per
  second!
• Private line optical service means low latency
  and jitter
• 10 X the speed of Gigabit Ethernet! (GigaMAN)
• 223 X the speed of a DS3!
• 6477 X the speed of a DS1!

15
DecaMANSM GigaMAN Comparison

• DecaMAN is similar to GigaMAN
• Deployed over SBC expansive Wave Division
  Multiplex (WDM) Network Nortel OM5000
• WDM allows for multiple circuits over single
  fiber when needed
• Carrier grade network, equipment and personnel
  Not All Ethernet Services Are the Same!
• Supports Ethernet standard interfaces (as
  specified)
• Fully managed by SBC 24x7
• Similar rate structure (channel terminations
  mileage) options for diversity and protection

• DecaMAN is different from GigaMAN
• At 10 Gbps, DecaMAN is 10 times the capacity of
  GigaMAN
• LAN PHY service will be priced in range similar
  to 3X GigaMAN (not exactly, may vary)
• DecaMAN supports two types of service, LAN PHY
  and WAN PHY
• Most circuits will be deployed without Network
  Terminal Equipment (NTE) on customer premises

16
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

17
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 high-quality network and is
  available in all SBC regions.
