This guide dives into the practicalities of 80km and 120km long-haul SFP modules, including key technologies, use cases, and best practices to optimize link reliability and cost of ownership. Long-haul SFP modules are designed to transmit data over extended optical fiber spans. We offer both the DWDM-100G-Q28-120 and the DWDM2-100G-Q28-80, and we also frequently get a lot of questions regarding these modules, their differences, and their specifications. SFP (Small Form-factor Pluggable) modules have evolved beyond short-reach Ethernet, enabling reliable 80km and 120km links with optical performance, wavelength management, and power efficiency. Meta Description: Explore Svelol's 10G SFP+ 1550nm dual-fiber optical module, offering 120km reach for metro networks, data center interconnects & long-haul communications. As global network operators accelerate the deployment of 400G long-haul and DCI (Data Center Interconnect) networks, the demand for high-capacity, long-reach, and wavelength-flexible optical modules continues to grow. The AO+-5192-EZR120 converts a 10Gb/s serial electrical data stream to 10Gb/s optical output signal and a 10Gb/s optical input signal to 10Gb/s serial.
