QSFP-100G-DR Juniper 100GB/s 100GBase-DR SMF 500m QSFP28 Transceiver

QSFP-100G-DR Overview

The Juniper Networks is a 100GBASE-DR (DR1) optical transceiver designed for short-to-medium range transmission over single-mode fiber. It uses a single wavelength around 1310nm with PAM4 modulation to deliver full 100Gbps over a standard duplex LC connection.With a reach of up to 500 meters, this module is ideal for intra-data center links, spine-leaf architectures, and high-density cloud environments where efficient fiber usage is important.Unlike SR4 or CWDM4/LR4 optics, this is a single-lambda (1×100G) solution, meaning it transmits all 100Gbps over one optical channel instead of multiple wavelengths or parallel fibers, reducing complexity and improving scalability.
