The 12 Fibers Singlemode LC/UPC Unjacketed Color-Coded Fiber Optic Pigtail is a high-density fiber optic solution designed for efficient network connections. It features LC/UPC connectors on one ends, ensuring low insertion loss and high return loss for optimal signal transmission. The unjacketed fiber design allows for easy splicing and customized installations, making it ideal for optical distribution frames (ODFs) and network deployment. The color-coded fibers follow the TIA/EIA-598 standard, facilitating quick identification and management. Utilizing singlemode fiber such as G.652D or G.657A1/A2, it supports long-distance and stable transmission, making it widely used in data centers, FTTH, fiber optic sensors, and communication networks.
