3.2.8 10GBASE-ER/10GBASE-EW Single-Mode Optical Fiber Cable
(Core Diameter: 10 μm, SC Twin-Core Connector)
This is used for the connection with 10GBASE-ER/10GBASE-EW.
The boundary with 10GBASE-ER/10GBASE-EW is the connector on GS4000.
The maximum transmission distance between the devices with 10GBASE-ER/10GBASE-EW
when using an optic fiber which core/clad diameter is 10/125μm (wave length: 1300nm) is
40Km.
Figure 3.2-8 shows the rough sketch of the cable, and Table 3.2-13 shows the specification of
an optic fiber interface.

Transmission loss
Dispersed yield strength
(Note 1) Use an optical fiber cable which wavelength is 1300nm.
(Note 2) The transmission loss during optical transmission should be at least 5dB. Use an optical attenuator to adjust the
transmission loss when it is under 5dB.
*
This cable should be used as a patch Cable. Figure 3.2-9 below shows an example of the
interface connection using it.
