This 1-meter (3.28 feet) SC/UPC to SC/APC single-mode duplex fiber optic cable is engineered for high-performance fiber optic connections. Featuring an SC connector with UPC polish on one end and an SC connector with APC polish on the other, it minimizes signal reflection and ensures reliable transmission. The cable uses 9/125µm single-mode fiber, often G.657.A2 grade, which is bend-insensitive for flexible installation. Its LSZH armored jacket offers fire resistance and rodent protection. With low insertion loss (≤0.15dB) and high return loss (≥55dB), it supports fast Ethernet, Fiber Channel, and CATV applications while complying with RoHS standards.
