20.1.4 10GBASE-R
This section describes an Ethernet interface that uses a 10GBASE-R optical fiber cable.
- <Structure of this section>
(1) Connection interface
10GBASE-SR,10GBASE-LR,10GBASE-ER,10GBASE-ZR, and 10GBASE-BR are supported. The transmission speed and duplex mode settings are fixed at 10 Gbit/s and full duplex.
- 10GBASE-SR
-
Used to connect between short distances (multi-mode, transmission distance: max. 300m *).
- #
-
The maximum distance depends on the cable used. For the transmission distance for each cable, refer to the "Hardware Instruction Manual".
- 10GBASE-LR
-
Used to connect between medium distances (single-mode, transmission distance: max. 10km).
- 10GBASE-ER
-
Used to connect between long distances (single-mode, transmission distance: max 40km).
- 10GBASE-ZR
-
Used to connect between long distances (single-mode, transmission distance: max 80km).
- 10GBASE-BR
-
By using light with differentwavelength in transmission and reception, as in the case of 1000BASE-BX, two-way communication can be performed with single-core optical fibers. This reduces the cost of optical fibers.
Because the upstream and downstream wavelengths are different, a pair of transceivers must be provided for each upstream and downstream.
- 10GBASE-BR10-D/10GBASE-BR10-U
-
Used to connect between medium distances (single-mode, max 10km).
- 10GBASE-BR40-D/10GBASE-BR40-U
-
Used to connect between long distances (single-mode, max 40km).
(2) Connection Specifications
For the physical specifications of the Switch, refer to the "Hardware User's Manual."
(3) Notes on connection
-
Operation is not guaranteed if a transceiver other than the one shown in the "Hardware Instruction Manual" is used.
-
10GBASE-BR and 10GBASE-ZR are vendor-specific, so operation cannot be guaranteed when connected to equipment from other vendors.
-
When using a direct attach cable, it takes 5 to 8 seconds to link up.
