What type of pigtail is used for G655 optical cable

G655 optical cables typically use single-mode fiber pigtails with SC, LC, or ST connectors, 9/125 µm core/cladding, and tight-buffered jackets suitable for fusion or mechanical splicing.Fiber Type and SpecificationsG655 pigtails are made from G.655 non-zero dispersion-shifted single-mode fiber (NZ-DSF), optimized for long-haul and high-capacity transmission systems. They have a 9/125 µm core/cladding diameter, which is standard for single-mode fibers, ensuring compatibility with G655 cables and minimal signal distortion over long distances .Connector TypesCommon connectors for G655 pigtails include:SC (Subscriber Connector): Snap-in, push-pull latching, durable, low insertion loss (50 dB)LC (Lucent Connector): Small form factor, widely used in high-density applicationsST (Straight Tip): Bayonet-style coupling, reliable for single-mode connections Jacket and BufferG655 pigtails are typically tight-buffered with outer jackets made of LSZH (Low Smoke Zero Halogen) or PVC, providing flexibility, fire safety, and environmental protection. The standard jacket color for single-mode G655 fiber is yellow, aiding in quick identification during installation .Applications and SplicingThese pigtails are designed for fusion or mechanical splicing to main fiber runs, making them ideal for:Long-distance telecom networksBackbone infrastructureMetropolitan area networks (MANs)Data centers and FTTH deployments They ensure low insertion loss, high return loss, and reliable performance in high-density or tight-bend environments .SummaryFor G655 optical cables, the recommended pigtail is a single-mode 9/125 µm fiber with SC, LC, or ST connectors, tight-buffered LSZH or PVC jacket, and designed for fusion or mechanical splicing, providing optimal performance for long-haul and high-capacity optical networks.
