Synology E25G21-F2, Internal, Wired, PCI Express, Ethernet, 25000 Mbit/s, Black, Blue, Silver
High-performance connectivity upgrade
The E25G21-F2 adapter gives you more connectivity options with support for SR and LR transceivers and DAC options. Dual 25GbE SFP28 ports help remove network bandwidth limitations, while backwards compatibility with 10GbE SFP+ equipment reduces installation and implementation costs. CPU offloading technologies reduce network transfer overhead on the host system's processor to boost system performance.

| Ports & interfaces | |
| Connectivity technology The technology that enables connectivity of the device, e.g. wired or wireless. | Wired |
| Host interface Interface that enables a host controller to communicate with a driver. | PCI Express |
| Interface Interface ports to connect pieces of equipment. USB (Universal Serial Bus) has become the most popular wired interface to connect peripherals. USB 2.0 supports speeds up to 480 Mbit/s (USB 1: 12 Mbit/s). The interface FireWire is also known as the IEEE 1394 standard. Enhanced IDE (EIDE)is sometimes referred to as Fast ATA, Fast IDE or ATA-2. | Ethernet |
| Fiber optic connector This terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all there have been about 100 types of optic fiber connectors produced. | SFP28 |
| Network | |
| Maximum data transfer rate The maximum speed with which data can be transmitted from one device to another. | 25000 Mbit/s |
| Networking standards The way in which the network is working, e.g. IEEE 802.11a, IEEE 802.11b, IEEE 802.11g. | IEEE 802.3ad,IEEE 802.3ae,IEEE 802.3by |
| Full duplex A full-duplex system allows communication in both directions, and unlike half-duplex, allows this to happen simultaneously. |
