High-Speed Optics for Scalable Networks

Network transceivers combine a transmitter and receiver to deliver high-bandwidth, low-latency links between switches, servers, and storage. From compact SFP transceiver modules to high-density QSFP module options, plus versatile media converter solutions, you can build 10G/25G/40G/100G backbones that fit today’s needs and tomorrow’s growth.

Common Form Factors & Speeds

Fiber Types, Wavelengths & Specialties

Match optics to distance and cable: SR for short multimode runs, LR/ER for long single-mode links. BiDi SFP single-mode cuts fiber strands in half, while CWDM/DWDM SFP multiplies capacity over the same fiber pair. Need copper? Try an RJ45 SFP copper module for short copper segments.

Buying Checklist

Confirm required speed (10G/25G/40G/100G) and form factor (SFP/SFP+/SFP28/QSFP/QSFP28), choose SR/LR per distance, and verify connector type and cable (OM3/OM4 multimode vs. single-mode). For copper-to-fiber bridging or PoE islands, add an Ethernet-to-fiber media converter. If you’re uplinking servers, pair your optics with the right Network Interface Cards and a compatible switch for end-to-end stability.

Deployment Examples

Access & Edge: 10G SFP+ SR uplinks from access switches to distribution.

Server & Storage: 25G SFP28 LR for spine/leaf or iSCSI/NFS back-ends.

Aggregation & Core: 40G/100G QSFP for compact, high-throughput spines.
