A fiber-optic network card is a device that can be used directly to connect to a network.
Fiber network card, refers to the fiber-optic Ethernet adapter, referred to as fiber-optic network card, the name of fiber Ethernet adapter. Follow the Ethernet communication protocol for signal transmission, Fiber NIC Card which is generally connected to the fiber optic Ethernet switch through the fiber optic cable.
According to the transmission rate can be divided into 100Mbps, 1Gbps, 10Gbps;
According to the type of motherboard socket can be divided into PCI, PCI, PCI (x1/x4/x8/x16) and so on;
By the type of interface into LC, SC, FC, St and so on.
Fiber network card is this the name of the optical fiber port HBA card?
In fact, we often say that the fiber network card refers to the fiber channel network of the HBA card.
Because of the different transmission protocol, Fiber NIC Card the network card can be divided into three kinds, one is Ethernet card, the other is FC network card, and three is iSCSI network card.
• Ethernet Card: Ethernet Adapter, the transport protocol is an IP protocol, typically connected to an Ethernet switch through a fiber optic cable or twisted pair. The interface types are divided into optical and electrical ports. Optical ports are generally transmitted through fiber optic cables, the interface module is generally SFP (transmission rate GB) and Gbic (1gb/s), the corresponding interface is SC, ST and LC. The current commonly used interface type is RJ45, it is used to connect with twisted pair, also has interface with coaxial cable, Fiber NIC Card but now it is used less.
·FC network card: Generally also known as fiber network card, the name of Fibre Channel HBA. A transport protocol is a fibre Channel protocol that is typically connected to a fibre Channel switch through a fibre optic cable. The interface types are divided into optical and electrical ports. Optical ports are generally transmitted through fiber optic cables, the interface module is generally SFP (transmission rate GB) and Gbic (1gb/s), the corresponding interface is SC and LC. Fiber NIC Card The interface type of the electric port is generally DB9 needle or HSSDC.
·ISCSI Network card: The name of the iSCSI HBA, Transport iSCSI Protocol, interface type and Ethernet card.
"Fiber network card" is generally referred to as FC HBA card, plugged into the server, the external storage of the fiber switch; the Ethernet card of the optical port is generally called "Fiber Ethernet card" and is also plugged into the server, but it is externally connected with an Ethernet switch with an optical port.
HBA Card: Fc-hba card (commonly known as: Fiber network card), ISCSI-HBA card (RJ45 interface)
