Fiber optic cable ST multimode dual core

ST-ST multimode dual-core fiber cables are designed to transmit data over two separate multimode cores using ST connectors, ideal for short-distance, high-bandwidth applications.OverviewA dual-core fiber contains two separate light-transmitting channels (cores) within a single fiber structure, allowing simultaneous bidirectional or parallel data transmission, effectively doubling the data capacity compared to a single-core fiber . In multimode fibers (MM), the cores are larger (typically 50 or 62.5 µm), enabling multiple light paths, which is suitable for short-distance communication such as within buildings or data centers .ST-ST ConnectorsST connectors (Straight Tip) are bayonet-style connectors commonly used in multimode fiber networks. An ST-ST cable has ST connectors on both ends, providing secure, quick connections for patch panels, switches, or network devices . These connectors are compatible with standard ST ports and are widely used in legacy and industrial networks.Technical SpecificationsCore Type: Multimode (OM1, OM2, OM3, or OM4 depending on application)Core Size: Typically 62.5/125 µm (OM1) or 50/125 µm (OM2/OM3)Bandwidth: OM1 supports 200 MHz·km at 850 nm and 500 MHz·km at 1300 nm Jacket Type: OFNR (Riser rated) or other flame-retardant options for indoor installations Cable Configuration: Duplex or dual-core, allowing two independent channels in one cable Advantages of Dual-Core Multimode FibersIncreased Data Throughput: Two cores allow simultaneous transmission of separate signals, effectively doubling capacity.Short-Distance Efficiency: Multimode fibers are cost-effective for distances up to 500 meters, ideal for LANs and campus networks.Ease of Installation: ST connectors provide reliable, repeatable connections with minimal insertion loss.Flexibility: Custom lengths, jacket types, and connector combinations are available to meet specific network requirements .ApplicationsLocal Area Networks (LANs)Data centers and server roomsIndustrial automation networksShort-haul telecommunicationsPatch panels and interconnects requiring dual-channel transmissionConsiderationsMode Coupling: In dual-core fibers, light can couple between cores if they are too close, potentially affecting signal integrity .Distance Limitation: Multimode fibers are not suitable for long-haul transmission due to modal dispersion.Connector Maintenance: ST connectors require clean, dust-free connections to prevent signal loss or damage . In summary, ST-ST multimode dual-core fiber cables combine the benefits of multimode transmission with dual-core capacity and ST connector reliability, making them ideal for short-distance, high-bandwidth network applications.
