(2) Connection interface: 1000BASE-X
The 1000BASE-SX, 1000BASE-SX2, 1000BASE-LX, 1000BASE-LH, and 1000BASE-BX
interfaces are supported. The transmission speed and duplex mode settings are fixed at
1000 Mbit/s and full duplex.
1000BASE-SX:
This Ethernet interface is used for short-distance connections
(550m max. in multiple-terminal mode)
1000BASE-SX2:
This Ethernet interface uses a multiple-terminal mode optical fiber cable that
ensures a connection over two kilometers.
(2 km max. in multiple-terminal mode)
1000BASE-LX:
This Ethernet interface is used for medium-distance connections
(5 km max. in single-terminal mode, 550 m max. in multiple-terminal mode)
1000BASE-LH:
This Ethernet interface is used for long-distance connections
(70 km max. in single-terminal mode)
1000BASE-BX:
This Ethernet interface is a low-cost interface that uses a single-core optical fiber in
which different wavelengths are used for sending and reception.
Because the upstream and downstream wavelengths are different, a pair of
transceivers must be provided for each upstream and downstream switch.
The Switch supports the 1000BASE-BX10-D and 1000BASE-BX10-U interfaces,
prescribed in IEEE 802.3ah, and the 1000BASE-BX40-D and 1000BASE-BX40-U
interfaces, which are vendor-specific interfaces.
1000BASE-BX10-D/1000BASE-BX10-U:
1000BASE-BX40-D/1000BASE-BX40-U:
You can configure either of the modes shown below. Select the appropriate mode for the
network to be connected. The default for the Switch is auto-negotiation.

(a) 1000BASE-X connection specifications
The table below describes the configuration settings on the Switch and the connection
specifications for transmission speed and duplex mode (full or half) on a remote device. For
details about the physical specifications for the 1000BASE-X interface, see the Hardware
Instruction Manual.
This Ethernet interface is used for medium-distance connections
(10km max. in single-terminal mode)
This Ethernet interface is used for long-distance connections
(40 km max. in single-terminal mode)
