ZXR10 ZSR V2 Hardware Description
fibers and multimode optical fibers. The user may select one in accordance with the
particular situation.
l
Multimode optical fiber: Transmits signals by using multiple modes of light (for
short-distance transmission).
l
Single-mode optical fiber: Transmits signals by using a single mode of light (for
long-distance transmission).
Each optical fiber is composed of the fiber core, cladding layer, buffer layer, strengthening
layer, and the outer jacket. For the physical cross-sectional area of a fiber cable, see
Figure 10-7 Optical Fiber Cross-sectional Area
The fiber core is the optical transmission component located at the core. It is made of
silicon or glass. The chemical compositions of a fiber core are partially different from those
of the cladding layer, so that the light entering at a specified angle is reflected continuously
by the fiber core and cladding layer. Therefore, light remains in the fiber core during the
whole transmission process.
Optical Fiber Connectors
Selection of optical fiber connectors depends on the operating environment and devices.
The ZXR10 ZSR V2 router uses the following types of optical fiber connectors:
l
LC connector
l
SC connector
l
FC connector
Connectors at the two ends of the optical fiber can be of the same type or different types.
