Common Specifications of Communication Optical Cables

Communication optical cables are specified by fiber type, core size, attenuation, bandwidth, environmental rating, and installation standards.Fiber Types and Core SpecificationsOptical fibers are classified into single-mode and multimode types. Single-mode fibers (OS1, OS2) have a small core diameter of 9 microns, allowing long-distance, high-speed transmission with minimal signal loss. OS1 cables support distances up to 10 km at 10 Gbps with attenuation of 0.4 dB/km at 1310 nm, while OS2 cables can reach 40 km at 10 Gbps with 0.3 dB/km attenuation at 1550 nm . Multimode fibers have larger cores (50–62.5 microns), supporting multiple light modes for shorter distances. OM1 supports 300 meters at 10 Gbps, OM2 up to 550 meters, OM3 up to 1000 meters at 10 Gbps, and OM4 up to 550 meters at 40 Gbps .Attenuation and BandwidthAttenuation, measured in dB/km, indicates signal loss. Single-mode fibers have lower attenuation (0.3–0.4 dB/km), while multimode fibers have higher attenuation (3.0–3.5 dB/km). Bandwidth, expressed in MHz·km, determines data-carrying capacity: OM3 cables offer 2000 MHz·km at 850 nm, whereas OM1 provides 200 MHz·km .Cable Construction and Environmental RatingsOptical cables consist of a core, cladding, primary coating, and protective sheathing. Indoor cables are designed for flexibility, flame resistance, and ease of handling, often using tight-buffered fibers for direct connectorization . Outdoor cables are built to withstand temperature extremes, moisture, UV exposure, and mechanical stress. Indoor/outdoor cables combine both characteristics, reducing the need for splices .Standards and RecommendationsITU-T standards define optical fiber and system specifications. For example, G.652 specifies single-mode fiber characteristics at 1310 nm, while G.957 and G.955 cover system performance for synchronous digital hierarchy (SDH) and PDH systems . Repeater spacing and dispersion management are also considered in high-speed systems to maintain signal integrity over long distances .SummaryWhen specifying communication optical cables, key parameters include:Fiber type: single-mode (OS1/OS2) or multimode (OM1–OM4)Core diameter: 9 microns for single-mode, 50–62.5 microns for multimodeAttenuation: 0.3–0.4 dB/km (single-mode), 3.0–3.5 dB/km (multimode)Bandwidth: 200–2000 MHz·km depending on fiber typeEnvironmental rating: indoor, outdoor, or indoor/outdoorStandards compliance: ITU-T G.652, G.957, G.955 for performance and interoperability These specifications ensure reliable, high-speed data transmission tailored to the installation environment and network requirements .
