PCI Express 10 Gigabit Ethernet Fiber Network Card w/ Open SFP+ - PCIe x4 10Gb NIC SFP+ Adapter

Different optical cables are needed for different applications. Before you select a cable to interconnect fiber devices, make sure that the following things match:

• Mode: Single Mode or Multi Mode.

• Wavelength: For example, 850 nm, 1310 nm, or 1550 nm.

Note: The above properties cannot be converted or changed by a cable.

When you select a cable, make sure that the cable ends (for example, LC, SC, ST, or MT) match the fiber media devices.

Simplex and duplex ends are available for most connector types. Simplex cables have the connectors separate, where duplex cables have the transmit (TX) and receive (RX) connectors joined together.  

It does not matter which diameter or OM classification the cable uses, as long as it meets the mode requirement.

When you use fiber devices and cables, make sure that the same fiber standards are being used on either end of the fiber network.

Starting in High Sierra 10.13, macOS enforces stricter security policies than previous revisions. As a result of these changes, software packages, like those used in this installation, will need to be allowed within the macOS Security and Privacy settings, immediately after the software has been installed, in order for the device to operate.

To allow the software, follow these steps after you've completed installation on your Mac:

1. Open System Preferences.
2. Open Security & Privacy.
3. Click the Allow button near the bottom of the General tab.

Note: The option to allow the software will be available within the Security & Privacy settings for 30 minutes. If the software is not allowed within that time frame, the software must be reinstalled in order for macOS to grant the opportunity to allow it again.

Before you install the device, make sure that your operating system is current (for example, the most recent service pack is installed).

1. Navigate to http://www.StarTech.com/Support and download the latest software. The part number and product ID are on the product packaging.

To confirm that Windows detects your expansion card, complete the following:

1. Press the Windows key+R, type devmgmt.msc, and press Enter.
2. In Device Manager, under the appropriate heading, confirm that your expansion card is listed and that there isn't an exclamation mark next to it.  For example, a USB controller card would be under Universal Serial Bus controllers.

Your expansion card is listed according to the name of the chipset. To determine the name of the chipset of your expansion card, navigate to www.StarTech.com and look on the Technical Specifications tab for your product.
