Functional Descriptions
The AT-2712FX/SC, AT-2712LX20/SC, and AT-2912T adapters feature
in-built cryptographic processors that take over a number of data
encryption and decryption functions within the hardware, releasing the
host CPU to perform other tasks. This ensures the highest possible
speeds when transmitting or receiving secure data, without compromising
data security or host system performance.
As part of the company’s green range, all three adapters are engineered
to reduce power consumption. They incorporate centralized power
management features that automatically place idle circuitry into a lower
power mode to save energy and battery life in a laptop.
The following sections provide functional descriptions of the AT-2712FX/
SC, AT-2712LX/20SC, and AT-2912T adapters.

Adapters
Both the AT-2712FX/SC and AT-2712LX20/SC adapters connect a PCIe
compliant server or workstation to a Fast Ethernet network using fiber
optic cabling and a connector. In addition, both adapters operate at
speeds of 100 Mbps in full-duplex and half-duplex modes. The two
adapters are identical in appearance. The AT-2712FX/SC adapter is
shown in Figure 1.
Figure 1. AT-2712FX/SC Adapter
Both the AT-2712FX/SC and AT-2712LX20/SC adapters have one SC
connector. The AT-2712FX/SC adapter uses a connector that meets 62.5/
125 µm or 50/125 µm multimode specifications. AT-2712LX20/SC adapter
uses a connector that meets 9/125 µm single-mode specifications.
