μ
m
,
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 GR4000.
The maximum transmission distance between the devices with 10GBASE-
ER/10GBASE-EW when using an optic fiber which core/clad diameter is 10

(
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.

(Note 1) Use an optical fiber cord 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.

NOTE: The values shown in Table 3.2-13 are complying with IEEE802.3ae.
This cable should be used as a patch cord. Figure 3.2-9 below shows an example of the
interface connection using it.
