## Connect a 10GbE Copper Network Cable

Depending on your copper adapter, the cabling type used is 10GBASE-T or CX4.

#### 10GBASE-T

Maximum lengths for Intel® 10 Gigabit Server Adapters and Connections that use 10GBASE-T on Category 6, Category 6a, or Category 7 wiring, twisted 4-pair copper:

- Maximum length for Category 6 is 55 meters.
- Maximum length for Category 6a is 100 meters.
- Maximum length for Category 7 is 100 meters.

Intel® 10 Gigabit Server Adapters and 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.

To ensure compliance with CISPR 24 and the EU's EN55024, Intel® 10 Gigabit Server Adapters and Connections 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® CX4 Dual Port 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 O, twinaxial cable characteristics. However, commercial cable manufacturers may offer enhanced products that will permit successful operation over greater distances. |

### 82598-Based Adapters

| NOTES: Intel® Network Adapters that support removable optical modules only support their original module type (i.e., the Intel® 10 Gigabit SR Dual Port Express Module only supports SR optical modules). If you plug in a different type of module, the driver will not load. 82598-Based adapters support all passive direct attach cables that comply with SFF-8431 v4.1 and SFF-8472 v10.4 specifications. Active direct attach cables are not supported. Hot Swapping/hot plugging optical modules is not supported. Only single speed, 10 gigabit modules are supported. LAN on Motherboard (LOMs) may support DA, SR, or LR modules. Other module types are not supported. Please see your system documentation for details.

## 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® 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® 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. |
