Single Mode 1310nm
Single Mode 1310nm refers to optical transceiver modules operating at a wavelength of 1310nm over single-mode fiber (SMF), which features a small core diameter (8-10μm) to support long-distance, high-speed data transmission with minimal dispersion and low attenuation. These modules are widely deployed in metro networks, data center interconnects, and telecommunication backbone systems. Their ability to balance cost efficiency and performance makes them ideal for scenarios requiring reliable signal integrity over extended spans.
Among our product list, the following modules utilize Single Mode 1310nm technology:
● 100G QSFP28 LR4: Designed for 10km links, leveraging four 25G lanes at 1310nm.
● 100G QSFP28 ER4/ER4 Lite: Extends reach to 40km with enhanced power efficiency.
● 100G QSFP28 DR1/FR1/LR1: Optimized for 500m-10km applications using 1310nm wavelengths.
