(3) 1000BASE-LX Single-mode Optical Fiber Cord
(Core diameter: 10µm，LC twin- core connector)
This is used for the connection with 1000BASE-LX（SFP-LX）.
The boundary with 1000BASE-LX is the connector on GR4000.
The maximum transmission distance between the devices with 1000BASE-LX when
using an optic fiber which core/clad diameter is 10／125μm （wave length: 1300nm） is
5Km.
Figure 3.2-3 shows the rough sketch of the cable, and Table 3.2-5 shows the
specification of an optic fiber interface.
