40 Gigabit QSFP+ transceivers designed for high-bandwidth data-center and enterprise network connections, supporting compatible switches, routers, servers, and optical infrastructure.
Optical Transceiver & Fiber Interconnect Selection Guide
Selecting the right optical module or cable requires matching the network speed, interface, fiber type, transmission distance, connector, and equipment compatibility.
1. Form Factor & Network Speed
Choose a transceiver that matches the physical interface and supported network speed of your switch, router, server, or NIC. Common enterprise form factors include: SFP / SFP+ (1G and 10G), SFP28 (25G), QSFP+ (40G), and QSFP28 (100G). Actual supported speeds depend on the individual device and transceiver.
2. Fiber Type & Transmission Distance
Select the optical module according to the required transmission distance and fiber infrastructure. Multimode fiber (MMF) is commonly used for shorter data center and building links, while single-mode fiber (SMF) is generally preferred for longer-distance network connections. Always match the transceiver's wavelength, fiber type, connector, and distance rating with the installed fiber infrastructure.
3. DAC vs. AOC vs. Optical Transceivers
For short server-to-switch connections, DAC cables provide a simple and cost-effective solution with low power consumption. AOC cables combine optical transmission with integrated transceivers and can be useful for longer short-range connections where copper DAC may not be suitable. Separate optical transceivers and fiber patch cables provide greater flexibility for network deployments where different distances, fiber types, or connection paths are required.
4. Vendor Compatibility & Coding
Transceiver compatibility can depend on the switch, router, NIC, firmware, vendor coding, and optical specifications. Before purchasing, verify the required vendor compatibility and ensure that the selected module matches the equipment's supported optical specifications.
