Transcription

1 Fiber Optic Specifications All Fiber Optic shall be Corning Altos Single Mode OS1 Outdoor Loose Tube Gel Free Cable Corning Fiber Products only will be accepted and no substitutions or alternates will be accepted or considered. There shall be a minimum of 12 Strands of Single Mode OS1 Fiber Terminated per Building and Dedicated as home run from each Fiber IDF to the Fiber MDF located in Building R, E, & F. The Fiber Optic MDF will be located in Building R, E, & F where CNS MPOE is Terminated. The following Buildings will be listed as Fiber IDF s: A, B, C, D, G, H, I, J, K, L, M, N, O, P, Q, S Splice Points will be labeled as SP 1 SP 6 There will be no Mechanical Splices or Mechanical Connectors All Fiber will be Fusion Spliced Fiber Connector Terminations will be Factory made Pigtail Cassettes Fusion Spliced to Trunk or Branch Cabling All Fiber Connector Terminations shall be LC type. All Fiber Terminations are to be Rack Mounted in Customer Provided Wall Mount or Free Standing Racks or Data Cabinets. All Exterior Fiber Cabling between buildings shall be installed in Customer provided conduit system. All Interior Fiber Optic Cabling will be installed in above ceiling area within each building. Customer Provided Conduit shall be no less than 4 inch in diameter and all bending or change of direction of conduit shall adhere to Fiber bend radius specifications. There shall be a minimum of 40 feet of service loop secured in the above ceiling area at each end of each fiber cable run. Page 1 of 5

2 The Fiber Cable Plant design will be as follows: Star Topology 240 Strand Trunk cable will originate at MDF R, E, & F and connect to IDF S at SP 1 IDFs C, D, G, & H will be spliced to the 240 Strand Trunk Cable at IDF S at SP 1 IDF S 12 Strand Fiber Cassette will be spliced to the 240 Strand Trunk Cable at SP Strand Trunk cable will connect IDF S to IDF A at SP 2 IDF B & Q will connect to IDF A SP 2 IDF A 12 Strand Fiber Cassette will be spliced to the 192 Strand Trunk Cable at SP Strand Trunk Cable will connect IDF A to IDF N at SP 3 IDF N 12 Strand Fiber Cassette will be spliced to the 144 Strand Trunk Cable at SP Strand Trunk Cable will connect IDF N to IDF M at SP 4 IDFs I, K, L, P will be spliced to the 144 Strand Trunk Cable in building M at SP 4 IDF M 12 Strand Fiber Cassette will be spliced to the 144 Strand Trunk Cable at SP 4 48 Strand Trunk cable will originate IDF M to IDF O at SP 5 IDF O 12 Strand Fiber Cassette will be spliced to the 72 Strand Trunk Cable at SP 5 48 Strand Trunk cable will originate IDF O to IDF J at SP 6 IDF J 12 Strand Fiber Cassette will be spliced to the 36 Strand Trunk Cable at SP 6 Each Fiber Strand will be Tested and Certified using Fluke Single Mode Fiber Tester and Test Results will be presented to Customer via USB Memory Device. Each Fiber IDF will be Labeled per above listings and each Fiber Connector will be Labeled as IDF-X- YYY (Whereas X represents the IDF Name as listed above and YYY represents the Fiber Numerical Count as ). Contractor will provide 2 each 3 Meter, Duplex, LC to LC Fiber Patch Cords per each IDF Location. Page 2 of 5

3 All Fiber Specifications are listed below and used as a minimum guideline. Dimensional Specifications Glass Geometry Fiber Curl >4.0 m radius of curvature Cladding Diameter ± 0.7 µm Core-Clad Concentricity < 0.5 µm Cladding Non-Circularity < 0.7% Coating Geometry Coating Diameter 245 ± 5 µm Coating-Cladding Concentricity <12 µm Environmental Specifications Environmental Test Test Condition Induced Attenuation 1310 nm, 1550 nm & 1625 nm (db/km) Temperature Dependence -60 C to +85 C* < 0.05 Temperature Humidity Cycling -10ºC to +85ºC* up to 98% RH < 0.05 Water Immersion 23º± 2ºC < 0.05 Heat Aging 85º± 2ºC* < 0.05 *Reference temperature = +23ºC Operating Temperature Range: -60ºC to +85ºC Optical Specifications Fiber Attenuation Maximum Attenuation Maximum Value* (db/km) ** *Maximum specified attenuation value available within the stated ranges. **Attenuation values at this wavelength represent post-hydrogen aging performance. Alternate attenuation offerings available upon request. Attenuation vs. Range Ref. λ Max. α Difference (db/km) The attenuation in a given wavelength range does not exceed the attenuation of the reference wavelength (λ) by more than the value α.

4 Macro-bend Loss Mandrel Number Induced Diameter of Attenuation* (mm) Turns (db) < < < < 0.03 * The induced attenuation due to fiber wrapped around a mandrel of a specified diameter. Point Discontinuity Point Discontinuity (db) 1310 < < 0.05 Cable Cutoff (λccf) Λ ccf 1260 nm Mode-Field Diameter MFD (µm) ± ± 0.5 Dispersion Dispersion Value [ps/(nm km)] 1550 < < 22.0 Zero Dispersion (λ0): 1310 nm < λ0 < 1324 nm Zero Dispersion Slope (S0): < ps/(nm 2 km) Polarization Mode Dispersion (PMD) Value (ps/ km) PMD Link Design Value < 0.06* Maximum Individual Fiber < 0.2 * Complies with IEC : 2001, Section 5.5, Method 1, September The PMD link design value is a term used to describe the PMD of concatenated lengths of fiber (also known as PMD Q). This value represents a statistical upper limit for total link PMD. Individual PMD values may change when cabled. Corning s fiber specification supports network design requirements for a 0.5 ps/ km maximum PMD. Page 4 of 5

5 Performance Characterizations Characterized parameters are typical values. Core Diameter 8.2 µm Numerical Aperture 0.14 NA is measured at the one percent power level of a one-dimensional far-field scan at 1310 nm. Zero Dispersion (λ0) 1317 nm Zero Dispersion Slope (S0) ps /(nm 2 km) Effective Group Index 1310 nm: of Refraction (Neff) 1550 nm: Fatigue Resistance Parameter (Nd) 20 Coating Strip Force Rayleigh Backscatter Coefficient (for 1 ns Pulse Width) Dry: 0.6 lbs. (3N) Wet, 14-day room temperature: 0.6 lbs. (3N) 1310 nm: -77 db 1550 nm: -82 db Stimulated Brillouin Scattering Threshold 20 dbm (1) Notes: (1) When characterized with a transmitter specifying 17 dbm SBS threshold over standard single-mode fiber. While absolute SBS threshold is a function of distance and signal format, SMF-28e+ fiber with NexCor technology offers a 3 db improvement over standard single-mode fiber independent of these variables. Mechanical Specifications Proof Test The entire fiber length is subjected to a tensile stress > 100 kpsi (0.7 GPa)*. *Higher proof test levels available. Length Fiber lengths available up to 50.4* km/spool. *Longer spliced lengths available. Page 5 of 5
