## 3.6. Network Interfaces

Sun Ray 3 Plus Clients can connect to networks via:

- One copper Gigabit 10/100/1000-Base T Fast Ethernet port

- One SFP socket to support optional fiber-optic networking modules

If both fiber-optic and copper interfaces are connected, the fiber-optic link is checked first. If the fiber-optic link is not valid, copper interface link is checked.

The Sun Ray 3 Plus Client includes an empty SFP (Small Form-factor Pluggable) network module slot in the back of the unit. This slot is intended to support commercial 1 Gb or 100 Mb optical fiber SFP network modules for customers who require optical network support.

- The SFP slot is intended for fiber-optic module use only. The client already includes a built-in copper Gigabit 10/100/1000-Base T Fast Ethernet port.

- Most 1000-X (Gb speed) compatible optical modules, such as 1000-SX or 1000-LX, should work unless they require a vendor-specific custom initialization.

- Certain 100-FX (100 Mb speed) optical modules should work with the following restrictions:

  - Each must have an SGMII (Serial Gigabit MII) interface. Many 100-FX SFP modules are designed only for direct 100 Mb slots, so they do not have an SGMII interface.

  - None can require a vendor-specific custom initialization.

- To connect to the SFP slot on a Sun Ray 3 Plus Client with an MT-RJ cable, use an MT-RJ to LC adapter. The following MT-RJ to LC adapters have been tested:

  - Fiber Optic Cable Shop FC-MTLC-MD6-1/6M

  - Cables To Go 3318x LC MTRJ DUP 62.5/125

The following table contains a partial list of fiber-optic modules that have been successfully tested.
