Fiber Infrastructure Revitalization

1
Fiber Infrastructure Revitalization

• SUNY Oswegos case study for the future of your
  information infrastructure 6/15/05.
• Timothy J Kraft
• RCDD, CCNA,NNDE
• 518.330.1188

2
The Problem (s)

• Campus Construction was going to break a major
  fiber connection.
• Several major new const. projects are planned.
• Many single mode fiber segments were completely
  full.
• Technology has moved beyond the ability of
  traditional multi-mode fiber.
• Facilities ignores networking costs for
  construction projects.
• We play catch up and work hard to find the money
  for some of these projects.

3
Define Requirements

• What are the immediate needs?
• Dorm renovations fiber break.
• Needs on the horizon (12 months)
• New Campus Center
• New Dorms
• Dept. Reorganizations.
• What are the long term needs
• Property the campus owns
• Long term building plans
• Physical Redundancy
• Major fiber cable is 10ft off of a new building
  foundation.
• It gets broken we have a major life safety issue.

4
Physical and logical redundancy
Physical Layout and Logical redundancy can be
very different things!
5
Decision Point 1

• Do we look at just this project or increase the
  scope?
• We increase the scope so that it fits a
  comprehensive plan.
• We only do the pieces we need for today.
• We size the project to its final design
• We get facilities involved, to know, to assist,
  and to team.

6
Define Assets (Pathways)

• Current assets and usage.
• Fiber audit (fiber type, usage, used)
• Facilities projects (teaming)
• GET IN EARLY!!!
• Existing facilities
• Duct Bank (existing, abandoned, ducts
  available)
• Pole Line (where they go, who owns them, space on
  Pole)
• Open field (where you can install fiber easily)
• Existing conduit and pathways.
• Direct bury fiber build (not in duct bank)
• no additions, CWDM for short term relief.
• Direct bury of conduit is a viable option today
  (Thruway)

7
Fiber Cable Construction

• Single Fiber or Hybrid (Single has only one type
  of fiber, Hybrid has more than one.)
• Tight Buffer, like what you see in a building. (1
  fiber to 1 jacket)
• Strong cable can be used in riser and plenum
  spaces.
• Loose Tube outside cable (12 fibers per 1 straw
  like tube)
• Gel filled non-fire retardant
• Cheaper 50 limit inside of building then
  transition
• Powder filled limited fire and smoke
• More expensive, but you do not have to
  transition. (saves money on splicing)

8
Fiber Termination (loose tube)

• Types of connectors available (common)
• ST are no longer supported!
• SC for fiber terminations
• LC for small form factor equipment
• Types of Terminations
• Breakout with direct heat or mechanical
  termination.
• Labor intensive, cheaper parts
• Pigtail splicing (Fusion or mechanical)
• Less labor, higher costs for pigtail.
• Mechanical
• Cheaper to do, OK performance, OK length of use.
• Fusion
• Slightly more expensive, Great performance, Great
  life expectancy

9
Decision Point 2

• What type of cable construction do we use?
• Loose Tube for all outside paths
• Ask for both types, dependent upon run.
• Contractor provides Powder filled for all runs
• Cheaper if they buy a single roll
• Hybrid Fiber, reduces space needs
• Make the major fiber runs uniform in size.
• Cheaper for contractor, cheaper for you.
• Fiber used 62.5/125 multi-mode and 9.2/125 single
  mode fiber
• Flexible inner-duct MAXCEL to reduce conduit
  usage. Space is a premium!

10
Types of Fibers

• Multi-Mode (medium distance, speed limitations,
  more expensive, cheaper GBIC electronics)
• 62.5/125 Pre 1996 (traditional US Multi-mode
  fiber)
• 62.5/125 FDDI (traditional US Multi-mode fiber)
• 50/125 (traditionally used in voice applications)
• 50/125 laser Optimized (new data grade product
  for building applications, VERY limited in
  outside plant applications)
• Single mode 9.2/125 (Distance, speed, cheap, more
  expensive GBIC electronics)

11
Data speeds Vs Distance
12
Fiber Counts

• Installation Labor is the most expensive cost!
• How many do you install?
• Maintain what you have in a building.
• Augment what is there.
• New Fiber routes to be installed (new buildings
  or redundancy)
• Increasing demand on single mode.
• 62.5/125 Multi-mode is not dead.
• 50/125 is not a outside building solution for a
  lot of campuses. (distance)

13
Cost comparisons

• Fiber (Corning Cable Systems 6/2005)
• Single mode 9.2/125 12 fiber/foot 0.30
• Multi-mode 62.5/125 12 fiber/foot 1.27
• Multi-mode 50/125 12 fiber/foot 1.08
• Multi-mode 50/125 LO 12 fiber/foot 2.318
• GBIC VCSEL (Vertical Cavity Surface Emitting
  Laser) (Cisco state Price 3/2005)
• 1000BASE-SX mm 340.00
• 1000BASE-LX sm/mm 676.00
• 1000BASE-ZX sm 2716.00

14
Cost comparisons (continued)

• Gigabit Equipment (Cisco NY state pricing 3/2005)
  
• Aggregation Point
• 3550-12G 10 GBIC / 2 Copper 6796.00 679.6/port
• Core Blade (6500)
• X6516 16 GBIC ports 13596.00 849/port

15
Decision Point 3

• Single mode fiber has a longer life span.
• We can operate in the VCSEL GBIC cost point.
• We can collapse our fiber core switching.
• Reduce complexity
• Reduce operational costs
• Prepare for another major renovation.
• Maintain the existing 62.5/125 multi-mode plant.
• Utilize the multi-mode for other types of
  services (security, cameras, fire/life safety
  building automation)
• Fiber used 62.5/125 multi-mode and 9.2/125 single
  mode fiber

16
Make your Plan

• Create a fiber backbone design
• Lay it out on a campus site plan
• Lay it out as a schematic
• Define build phases
• We can do anything, just not over night!
• Dependencies
• Duct Banks, Telecomm. rooms, Money, Conduits, etc
  
• Publish your Design
• Feed back, Senior management awareness,
  Multi-Dept. co-operation.

Decision Point 3

• Put in large quantity of single mode
• We are not terminating all of it just yet.
• Look to collapse the network.
• Financial study to be conducted. Stay tuned
• Standards based deployment
• We put in several phases.
• Store cable in one place until Facilities can
  build duct bank with steam tunnel.
• Re-terminate some exiting fiber
• Space, alignment, re-use of plant
• Break up funding associated with building
  projects.
• Pieces are done on different building contracts.

20
Summary so far

• We want to have a comprehensive deign
• We are going to use abandoned Power and Signal
  manholes use Maxcell.
• We will maintain the existing 62.5/125 mm system,
  but augment more toward single mode fiber. Loose
  tube with SC. We are using Corning glass.
• We have a schedule to meet.
• We are teaming with facilities on these projects
• We are going to get the project done while we
  have the money.
