5. Build an asset Fiber has a 20 year + life Any excess fiber can be leased or sold

6.  Multimode Fiber ◦ Large Core most common 62.5um ◦ Only good for < 4KM  Single Mode Fiber ◦ ITU-T G.652-Zero Dispersion around 1310 nm\ ◦ Supports CWDM and DWDM and Standard Ethernet  Dispersion Compensated Fiber ◦ ITU-T G.655-Zero Dispersion around 1550 nm ◦ Supports DWDM and Standard Ethernet @1550 nm ◦ Support Long Spans 50 KM+

7. Loose Tube Fiber ◦ Commonly used in lashed or under ground deployments. ◦ Has very little internal support. ◦ Fiber loose in buffer tubes to allow for temperature and moisture change. Armored Fiber ◦ Loose tube fiber with corrugated steel Armor ◦ Must be grounded

8. ◦ ADSS(All-Dielectric Self-Supporting)  Support and span length engineered into fiber  No grounding requirements  Installed using Pulleys Dead End with Slack

9. ADSS Minimum Bend Radius To arrive at a working bend radius for cable installation, multiply 20 times (20 x) the cable outside diameter. Cable Diameter = 0.46 in (11.8 mm) Example: 20 x 0.46 in = 9.2 in (177 mm) Minimum Working Bend Radius = 9.2 in (17.7 cm) To find the minimum diameter requirement for pull wheels or rollers, simply double the minimum working bend radius:

10. ADSS Tensions As temperature increases ADSS tension will also increase. This is opposite of ACSR (conductor) Incorrect tension can damage fiber over time

11. Single mode starts at $.25/foot

12. Ribbon Fiber  Efficient packaging of higher fiber counts  Lightweight and easy to handle during installation  Specialized Splicers to splice 12 Fiber simultaneously

13.  Optical Ground Wire (OPGW) ◦ Fiber optics engineered into ground wire(Shield) ◦ Wire and Fiber must be Pre-engineered for access of fiber optics( No access mid span) ◦ Lower cost than underground

14. Core Alignment Splicer Uses Servos and Camera to align core Very precise low loss splice Electrical Arc fuses Glass Must be cleaved V Groove Splicer Less Precise Lower cost to purchase and maintain Must be cleaved

15. Dome enclosures High Capacity enclosure Customizable using grommets Splice trays separate Typically used for butt connections Low Count enclosures Compact Size Low splice capacity Inline or Butt splices

17. ADSS Dead Ends Used to make high angle turns Must use for slack storage Creates Shear points Tangents Supports fiber between dead ends Line angle limitation < 20 degrees Some models can be used in pulling short spans 1. Keeper 2. Cushion Inserts (With or Without Grit) 3. Captured Bolt and Washer (Captured with Grommet) 4. Lock Nut 5. Anchor Shackle with Eye-nut (Optional not shown) 6. Structural Reinforcing Rods (optional, not shown)

18.  Lashed Fiber Fiber lashed to steel carrier Must be grounded Can not be installed in power space

19. SC (Subscriber Connector) Square connector Push-Pull snap LC (Lucent/little connector) Small high density Snap fit Used on Lasers(XFP/SFP) ST (Straight Tip) Round Twist lock Common in Sub Stations UPC (Ultra Physical Contact) polish style of fiber optic ferrules Standard for most applications APC (Angled Physical Contact) Has Lower lightwave reflectance Used in RF optical applications

20. Passive One Fiber 32 to 64 Customers Requires optical Splitters Bandwidth is Shared Active One Fiber One Customer Bandwidth not shared Requires high fiber counts Non Powered Optical splitter

21.  Sonet (Synchronous Optical Network)  Based on older Time Division Multiplexing T1-T3 Technology  Poor bandwidth Efficiency(Protection Path No bandwidth) Limited bandwidth sizes  Sub 50ms protection  High Deployment cost Active Path Reserved path No activity

22.  Ethernet ◦ Low Cost Deployment ◦ Flexible bandwidth rates ◦ Sub 50ms protection without stranding bandwidth ◦ Mesh and Ring Topologies ◦ Easily Scalable Active Path Secondary path Active Path

23. DWDM Multiplex up to 160 channels of bandwidth on 2 fibers Capable of long distance communications Wavelength sizes up to 100Gb Can use a digital wrapper(OTN) to encapsulate many types of data and maintain packet quality Most systems do not have protection

24. Standard Ethernet DWDM TXRCV TXRCV

25.  Layer 2 (Facts) 1. Switching determined by MAC address database 2. If Packet Collision occurs, packet randomly retries 3. Packet Broadcast transverses all switches on domain 4. Vlans provide segmentation of domain 5. Vlans also allow for security and network traffic flow management
