Orientalfiber Factory’s 3mm Round Cable LC/UPC-to-LC/UPC Patch Cords are designed utilizing G657A1 single-mode fiber and high-precision LC/UPC connectors. With a primary focus on controlling insertion loss and return loss, these cords ensure stable, high-speed transmission performance while guaranteeing a return loss of ≥50dB. The 3.0mm LSZH outer jacket enhances tensile and compressive strength, making the product suitable for a wide range of applications, including server room cabling, FTTH deployments, and industrial communications. Supporting over 800 repeated insertions and extractions with a minimum bending radius of ≥20mm, these patch cords undergo 100% factory testing to ensure an optimal balance between signal stability and practical installation durability.
