## Connect a 10GbE Copper Network Cable

#### 10GBASE-T

The Intel® 10 Gigabit AT Server Adapter uses 10GBASE-T on Category 6, Category 6a, or Category 7 wiring, twisted 4-pair copper:

- Length is 55 meters max for Category 6.
- Length is 100 meters max for Category 6a.
- Length is 100 meters max for Category 7.

Intel 10 Gigabit Server Adapters using copper connections automatically accommodate either MDI or MDI-X connections. The auto-MDI-X feature of Intel copper adapters allows you to directly connect two adapters without using a cross-over cable.

For the Intel® 10 Gigabit AT Server Adapter, to ensure compliance with CISPR 24 and the EU’s EN55024, this product should be used only with CAT 6a shielded cables that are properly terminated according to the recommendations in EN50174-2.

#### CX4

Physical cabling characteristics for the Intel® PRO/10GbE CX4 Server Adapter must meet IEEE Std 802.3ak, Clause 54 specifications. The required cable connector is an MDI latch-type receptacle, as defined by IEC 61076-3-113. The IEEE standard defines a worst-case cable length of 15 meters (49 ft.), based on 100 Ω, twinaxial cable characteristics. However, commercial cable manufacturers may offer enhanced products that will permit successful operation over greater distances. |

## Connect a 10GbE Fiber Network Cable

| CAUTION: This product uses a Class 1M laser module. Viewing the laser output with certain optical instruments designed for use at a distance (for example, telescopes and binoculars) may pose an eye hazard.

Remove and save the fiber optic connector cover. Insert a fiber optic cable into the ports on the network adapter bracket as shown.

Most connectors and ports are keyed for proper orientation. If the cable you are using is not keyed, check to be sure the connector is oriented properly (transmit port connected to receive port on the link partner, and vice versa).

For Intel® PRO/10GbE LR Server Adapters: Laser wavelength: 1310 nanometer (not visible). Cable type to use: Single-mode fiber with 9.0µm core diameter Connector type: LC. Maximum cable length: 10 kilometers. For Intel® PRO/10GbE SR Server Adapters: Laser wavelength: 850 nanometer (not visible). Cable type to use: Multi-mode fiber with 62.5µm or 50µm core diameter Connector type: LC or SC. Maximum cable length: 300 meters. The adapter must be connected to a compatible link partner, such as an IEEE 802.3ae-compliant 10-gigabit switch, which is operating at the same laser wavelength as the adapter. Conversion cables to other connector types (such as SC-to-LC) may be used if the cabling matches the optical specifications of the adapter, including length limitations. |
