Cisco QSFP-40G-CSR4= Network Transceiver Module Fiber Optic 40000

The physical interface or port used to connect a device to another component or system, such as USB, HDMI, RJ‑45, 3.5 mm jack, or fiber optic connectors. It indicates the shape, pin count, and electrical characteristics that determine compatibility with cables, adapters, and peripherals.

Specifies the type of wired Ethernet interface supported by a device, such as Gigabit Ethernet, 10 GbE, Fast Ethernet, or other variants. The value is a free‑text label that identifies the standard or generation of the Ethernet port(s) available on the product.

The physical medium used by the network cable or transceiver, such as twisted pair copper or optical fiber. This attribute indicates which types of cabling are compatible with the device and helps users select the appropriate cable for their networking setup.

The type of network interface or protocol supported by the product, such as wired Ethernet standards (e.g., 10/100Base‑T, 1000Base‑T, 10GBase‑T) or wireless technologies (e.g., Wi‑Fi, Bluetooth). It indicates the primary networking capability that can be used for data transmission.

The total count of Ethernet or other networking interfaces available on the device, expressed as a simple integer or a descriptive string that lists port types and quantities (e.g., "48 x Gigabit Ethernet + 4 x 10 Gigabit Ethernet"). This attribute indicates how many network connections the product can support.
