| 10 Gb/s | SFP+ to SFP+ | Server-to-switch links and short data-center connections | Active optical assemblies commonly use multimode fiber. Confirm the exact supported length and optical specifications for the selected model. | Check that both host ports support the required 10 Gb/s Ethernet mode and accept the AOC’s interface type. | Specify cable length, end-to-end configuration, quantity, and required product documentation on the purchase order. |
| 25 Gb/s | SFP28 to SFP28 | Server access links and 25 Gb/s data-center networks | Reach is assembly-specific; do not assume that a 25 Gb/s AOC has the same maximum length as another speed or model. | Verify support for the required 25 Gb/s link mode, port configuration, and equipment compatibility at both ends. | Request the datasheet and confirm the stated length, operating conditions, and labeling match the ordered part specification. |
| 40 Gb/s | QSFP+ to QSFP+ | Switch uplinks and data-center aggregation links | Confirm the assembly’s rated reach and fiber details in its datasheet; AOC reach is not set by the connector format alone. | Check that both devices support 40 Gb/s operation and the specific QSFP+ AOC configuration. | Agree on packaging, cable protection, carton quantities, and shipment terms before dispatch. |
| 100 Gb/s | QSFP28 to QSFP28 | High-density switch links, storage networks, and data-center fabrics | Available lengths vary by product. Order by the exact required length and verify maximum reach in the supplied product documentation. | Confirm the equipment supports the required 100 Gb/s port mode and AOC operation; check any platform-specific compatibility requirements. | For multi-country projects, confirm destination-specific import paperwork, declared product description, and country-of-origin information with the importer or broker. |
| 200 Gb/s | QSFP56 to QSFP56 | Higher-throughput data-center interconnects and switch-to-switch links | Reach and supported fiber characteristics depend on the assembly design. Obtain the exact model’s performance data before selecting a route length. | Verify that both ports support the intended 200 Gb/s mode and that the equipment can operate with the specified active cable. | Use a clearly defined specification sheet covering interface ends, line rate, length, and any requested inspection or test records. |
| 400 Gb/s | QSFP-DD to QSFP-DD or OSFP to OSFP | High-capacity data-center switching and network-core connections | Do not infer reach from the 400 Gb/s rate or form factor. Confirm the exact assembly’s rated reach, fiber type, and operating limits. | Check the host port form factor, supported link mode, device compatibility, and any required breakout configuration. | Confirm shipment quantities, protective packaging, traceable product identification, and applicable destination-market requirements. |
| Any listed rate | Split-end or breakout AOC, where supported | Connecting a higher-rate switch port to multiple lower-rate ports | Record the full end configuration, such as one high-rate end and multiple lower-rate ends. Confirm supported lane mapping and total cable length. | Check that the switch supports the required breakout mode and that the number and rate of remote ports match the cable configuration. | Ask for a pinout or configuration description and verify that the ordered ends and labels match the network design. |
