Product details
Overview
The FT-QSFP28-100G-SR4-850-2 is a 100G QSFP28 SR4 optical transceiver built on 4-lane 850 nm parallel optics with an MPO-12 connector. Each lane runs 25.78125 Gbps NRZ, reaching 100 m over OM4 and 70 m over OM3 multimode fiber. Center wavelength spans 840 to 860 nm, and average launch power per lane is -8.4 to 2.4 dBm. Power consumption stays at 2.5 W within a 0 to 70 °C case temperature range. The parallel-optics design suits high-density data center fabrics where one cable plant carries 100G natively.
