Glossaire de la fibre optique

Architecture mono-fibre : Sur la partie terminale du réseau en fibre optique, une architecture monofibre est caractérisée par une fibre unique qui relie le point de mutualisation à la prise terminale optique dans un logement. Architecture multi-fibres : Sur la partie terminale du réseau en fibre optique, une architecture multifibres est caractérisée par plusieurs fibres […]

Použité zkratky

V souvislosti s evolucí přístupových sítí se v současné době stále častěji diskutují optické, případně kombinované opticko-metalické přístupové přípojky označované jako FTTx (Fibre to the X), kde optická část přípojek bude založena na některé z variant pasivních optických přístupových sítí (PON), nejčastěji na variantě GPON (Gigabit Passive Optical Network) či EPON (Ethernet Passive Optical Network).

FTTx PON Insertion Loss Tests

Insertion loss tests are primarily used to test FTTx PONs (Passive Optical network) during installation. Insertion loss testing may be performed on individual fiber segments as they’re installed (e.g. test feeder fiber from Central Office  (CO) to Fiber Distribution Hub (FDH), test distribution fiber from FDH to AP, or test drop fiber from AP to […]

What is the difference Among OM1, OM2, OM3, OM4 and OM5

Multimode fibers are identified by the OM (“optical mode”) designation as outlined in the ISO/IEC 11801 standard. OM1, for fiber with 200/500MHz*km overfilled launch (OFL) bandwidth at 850/1300nm (typically 62.5/125um fiber) OM2, Type A1a.1 , for fiber with 500/500MHz*km OFL bandwidth at 850/1300nm (typically 50/125um fiber) OM3, Type A1a.2, for laser-optimized 50um fiber having 2GHz*km […]

PON-BASED GPON ARCHITECTURES INTRODUCTIONS

PON architectures for FTTH deployments are currently based on passive optical splitters to distribute the bandwidth to each customer using fiber splitters providing ratios ranging up to 1:64 or even 1:128. The physical PON FTTH architecture typically supports the Ethernet protocol. PON network feeds a variety of optical network terminations (ONTs) or optical network units […]

FTTH Deployment costs: expectations vs reality

Overview A new White Paper by the FTTH Council Market Intelligence Committee finds European FTTH deployment cost estimates are highly accurate. That makes investing in fibre highly attractive. To determine whether the FTTH cost estimates used in European projects accurately represent the actual costs, the FTTH Council approached a wide selection of parties involved in […]

UTP or STP for Copper for data center cabling?

Believe it or not, there is no straightforward answer to this question. Most countries in Europe have been using STP cabling for a long time, whereas in the US and in Canada, UTP has maintained dominance with over 95 percent of the installed base using UTP instead of STP. A best practice is to stay […]
