1 Kravspesifikasjon VTK Nett Generelle krav i nettet Generell krav til skjøtedemping: Generell krav til Refleksjoner i sveiseskjøter: IL < 0,2 db RL > 60 db Det tillates ikke mekaniske skjøter i stamnettet. Alle rør som ender på vegg eller innendørs, tettes med forsegling mellom kabel og rør med minimum 3 bar trykk mot vann og gass. Alle skjøtebokser i aksessnett må kunne organisere og ivareta bøyekontroll på hver enkelt fiber, ref. minimum krav gitt i 1.2 Functional optical requirements. I skjøtebokser mot kundetilkopling tillates maks 4 fiber pr kassett (Single Sircut). Gjennom skjøting av andre fiber i samme boks maks 12 fiber pr kassett (Single Element). I transportnett uten kundeaksess tillates kassetter med masse organisering (inntil 72 fiber pr kassett). Det kreves installasjonsbeskrivelse, kravspesifikasjon og datablad for alle optiske komponenter. For komponenter som i sin ytelse, form og kapasitet er variable kreves ordreguide. DEFINISJONER Masseorganisering Single Element Single Sircut Alle fibrer kan forlegges i en kassett inntil maks kapasitet, ingen bøyekontroll eller tiltak mot transienttap ved driftsendring (ny skjøt eller kundetilkopling). Alle fibrer i et fiberrør forlegges i en kassett, bøyekontroll og tiltak mot transienttap er ivaretatt ved driftsendring (ny skjøt eller kundetilkopling) Inntil 4 fiber forlegges i en kassett, bøyekontroll og tiltak mot transienttap er ivaretatt ved driftsendring (ny skjøt eller kundetilkopling) IL Innskuddsdemping db.

2 Kravspesifikasjon VTK Nett Målekriterier innskuddsdemping: IL Når det gjelder krav til parametre og målenøyaktighet, må det være et visst forhold. Normalt tar man høyde for en viss usikkerhet i kravet ved at man for eksempel adderer to ganger måleusikkerhetens standardavvik til det man mener er et fornuftig krav. Dersom fabrikanten skal følge dette kreves at de tilsvarende beregner samme forskjell i måleverdi ved sluttkontrollmålinger. Eksempel. Usikkerheten til IL måling er ca. 0,1 db. 2 ganger usikkerheten er 0,2 db. Med andre ord vil vi være mer enn 95 % sikre på at målingen er bedre enn 0,4 db dersom målingen viser 0,2 db. Ut fra denne tankegangen vil man typisk få produkter som har 0,2 db innskuddsdempning ved å kreve at den skal være 0,4 db. Målekriterier innskuddsdemping: RL Tilvarende gjelder for RL målinger. Det er vanskelig å måle med bedre enn 2 db usikkerhet slik at man ikke bør sette kravet høyere enn 50 db. Når det gjelder krav til parametre og målenøyaktighet, må det være et visst forhold.

Detaljspesifikasjoner er eksempler gitt av leverandør på aktuell kabel. Tilsvarende informasjon må forelegges hver enkelt forespurt kabeltype. Krav til fargekode, merking og standarder er identisk med dette eksempel: EKSEMPEL 1. Scope This document specifies a loose tube, self-support cable with a dielectric central member, containing up to 12 tubes; each tube contains up to 12 optical fibers. The cable jacket is PE. The cable shall be designed for aerial installation on an integrated self-supporting messenger. 2. Cable Description Optical cable for aerial installation on poles. The outer sheath should be made of abrasion resistant polyethylene. The cable should have a steel messenger wire suitable for up to 80 m span lengths. Span length should be dependent on ice load, wind load and installation sag. Ice load min. 3 kg/m, wind load 22m/sec. The figure-8 construction should allow easy installation with cable grips attached to the messenger wire. The cable core should be to prevent moisture penetration. The cable core should be non-metallic and should be easily separated from the steel messenger wire to eliminate problems with induced high voltages in termination and splice points. The fibers should be protected in jelly filled loose tubes stranded around a central strength member to ensure optimum performance and long life. Each fiber and loose tube should be color-coded for easy identification during splicing and termination. The outer sheath should be marked to show fiber type and cable type. Swelling tape are accepted as water-blocking 3. Reverse lay (SZ) stranding The elements (loose buffer tubes and if necessary filling elements) should be stranded around a central member according to the reverse lay method, which means, that the direction of stranding reverses after a predetermined number of revolutions. At the reverse point the elements are laying parallel to the axis of the cable. A binder should be wound around the elements in order to retain them in the proper position.

Scope This document specifies a loose tube cable with a dielectric central member, containing up to 12 tubes; each tube contains up to 12 optical fibers. The cable is designed for duct combined indoor and outdoor installation. 2. Cable Description Optical cable for duct installation. The outer sheath should be made of abrasion resistant polyethylene or high density polyethylene. To allow easy installation of long lengths, the cable should have a central FRP strength member, and is additionally reinforced with glass yarn around the cable core, which also reduces the chances for damages due to rodents. The cable should be non-metallic to eliminate any problem with induced electrical currents. Water swelling tape around the cable core should be used to prevent moisture penetration. The fibers should be protected in jelly filled loose tubes stranded around a central strength member to ensure optimum performance and long life. Each fiber and loose tube should be color coded for easy identification during splicing and termination. The outer sheath should be marked to show fiber type and cable type. The cable should contain at least two ripcords to easily remove outer sheet. 3.
