Selection Guide for Carrier Backbone Network Grade LPO Optical Module QSFP28
This guide breaks down NS-branded QSFP28 modules—SR4, LR4, and DR—with practical advice on reach, fiber types, connectors, power, DOM, interoperability, and lifecycle management. 100G QSFP28 optical transceivers have become the backbone of modern hyperscale data centers, enabling high-density 100Gbps connectivity with significantly lower power consumption (3. 5–6W) than legacy CFP/CFP4 modules (6–24W). This guide synthesizes technical specifications from IEEE/MSA standards. After reading, you will understand exactly what each QSFP28 module type does, when to use it, and how to match it to your specific fiber infrastructure and switch platform. Need help selecting the right module for your network? Explore Ascent Optics' QSFP28 transceiver portfolio or contact our. When a 100G rollout stalls, it is usually not the switch software; it is the optics fit. It is designed to carry 100 Gigabit Ethernet. Unlike older CFP. The SR4 is the most common 100G module in data centers. Each lane sends light through one fiber, so you need 8 fibers total (4 Tx, 4 Rx) in an MPO ribbon cable.
