# 100G LR ER ZR Dual fiber to Single fiber Converter

With the increase of 100G data transmission with large bandwidth, optical fiber resources between data centers are becoming less and less. How to reuse existing optical fibers can save considerable costs for enterprises. DFT provides 100G dual-port to single-port converter for bidirectional transmission of 100GLR4/ER4 optical modules over one core fiber, enabling multiple 100G services using the existing dual-core fiber.
