3.2.10 10GBASE-LR Single-mode Optical Fiber Cable
(Core Diameter: 10
μ
m, LC Twin-Core Connector)
This is used for the connection with 10GBASE-LR (XFP-LR).
The boundary with 10GBASE-LR is the connector on GS4000.
The maximum transmission distance between the devices with an optic fiber which core/clad
diameter is 10/125
μ
m (wave length: 1310nm) is 10 km.
Figure 3.2-11 shows the rough sketch of the cable, and Table 3.2-16 shows the specification of
optic fiber interfaces.
