Fiber Infrastructure Revitalization SUNY Oswego’s case study for the future of your information infrastructure 6/15/05. Timothy J Kraft RCDD, CCNA,NNDE 518.330.1188
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.
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.
Physical and logical redundancy Physical Layout and Logical redundancy can be very different things!
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.
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)
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)
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
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!
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)
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)
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
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
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
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.
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.
Request For Purchase • Complete design document! Ambiguity costs and costs and costs!!!!!! • Product specific, or Open • Specify terminations, cable construction, glass manufacture, fiber enclosures, fiber routing, inner-duct type, staging. • Distance Quotes are “Good Faith” Contractor responsible for cable all footages!
Request For Purchase (Continued-2) • Define testing procedures and how they are to be conducted with sign offs. • Bi-Directional TDR quote standards • Bi-Directional power meter (Define Wavelengths) • Soft copies of ALL results! • Bill of Materials • Define products, not quantities! • Campus has final say on any equivalents! • Termination locations • Where and How (racks,) • Wire Management (Vertical, Horizontal and Slack) • Labeling • Cables, Patch Panels, Splicing Detail etc • Scheduling (completed, contingencies)
Request For Purchase (Continued-3) • Clearly Define Change order Process. • What is acceptable. Who has authority to sign. Billing • Warranty Manufacture based! • Understand the warranty implications. • Provide “As Built Drawings” • Define what media and quantities • Put in Bidder Qualifiers, to provide flexibility in awarding contract. • Winning Deliverables to include Bill of Materials to be used, with part numbers and quantities. Financials, Similar projects, References, etc. • Fiber manufacture certifications • Splicing • Installers
RFP Alternatives • Remove old cable. • Duct banks are full of old abandoned cables • Make room for future projects. • The contractor is there in the manhole system, during new construction. • Re-termination • ST connectors are no longer supported • Space consolidation, 72 fibers to 144 • Testing re-terminated fibers for Quality Assurance
RFP Pricing • Budget Pricing for this piece $300K • Average adjusted bid price $265K • Winning Bid $177K • Lowest bidder usually forgets something. • Put in Bidder Qualifiers, to provide flexibility in awarding contract. • Winning Deliverables to include Bill of Materials to be used, with part numbers and quantities. • Fiber manufacture certifications (Splicing and pulling)
Project Management • Teamed with facilities to have electrical engineers oversee construction on site. • Manufacture provide splicing course and what to watch out for. • Define spot check system, to oversee contractor. • Check with manufacture on contractors
