Juniper QSFP-100GBASE-SR4 100Gb/s MMF DOM Optical Transceiver

Product Description

The Juniper QSFP-100GBASE-SR4 is a high-performance optical transceiver module engineered for 100 Gigabit Ethernet (100GbE) network applications. It utilizes the QSFP28 form factor, which is standard for high-density 100GbE deployments, allowing for a compact and efficient integration into compatible network equipment like switches and routers. This transceiver is specifically designed for short-reach connections over multi-mode fiber (MMF), making it ideal for within-data center interconnects, server aggregation, and high-performance computing clusters. The SR4 designation indicates that the module uses four parallel lanes, each operating at 25Gb/s, to achieve the aggregate 100Gb/s bandwidth. It employs an MPO/MTP connector, which is necessary to accommodate these multiple fiber strands. The transceiver operates at a wavelength of 850nm and is compatible with OM3 and OM4 multi-mode fiber, providing reach of up to 70 meters and 100 meters, respectively. This makes it suitable for typical data center cabling distances. A key feature of the QSFP-100GBASE-SR4 is its support for Digital Optical Monitoring (DOM). DOM functionality allows for real-time monitoring of critical transceiver parameters such as optical transmit power, optical receive power, temperature, and laser bias current. This capability is invaluable for network administrators, enabling proactive performance management, fault detection, and troubleshooting, thereby enhancing network reliability and uptime. This transceiver is a critical component for building high-bandwidth, scalable, and manageable data center networks.
