Learn about Network Transceivers

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

SFP / SFP+

Ideal for access and server uplinks. Popular picks include 10G SFP+ transceiver for short-reach SR or long-reach LR links, and copper options for short runs.

SFP28 (25G)

A sweet spot for modern servers and leaf-spine designs. Look for SR/LR variants such as 25G SFP28 LR to extend reach with single-mode fiber.

QSFP+ / QSFP28

Aggregation-friendly density for 40G/100G fabrics. For short top-of-rack links, consider 40G QSFP+ DAC (passive copper) or 100G QSFP28 AOC (active optical cable) to simplify cabling.

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.

Compatibility tip: Check vendor coding (brand compatibility), DDM/DOM support, operating temperature (industrial transceiver models), and switch/NIC firmware notes before purchasing.

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.

Frequently Asked Questions

How do I choose SR vs. LR?

Use SR on OM3/OM4 multimode for short in-rack or row links; choose LR on single-mode for long runs or building-to-building spans.

Can different brands interoperate?

Often yes, but check vendor coding/compatibility lists and DOM/DDM support on your switch or NIC to avoid alarms or link issues.

When should I use DAC or AOC instead of optics?

Use DAC for very short, low-cost in-rack links; pick AOC for longer top-of-rack runs without managing separate optics and fiber jumpers.

Related Essentials

Finish your build with the right cabling and hardware: SFP+ DAC cables, QSFP AOC, Ethernet cables, server racks & cabinets.
