Multimode and Single Mode glass optical cable requirements
Parameter
Glass Fiber Cable Length
Cable Attenuation @1300 nm
Modal Bandwidth @1300 nm
Chromatic Dispersion @1300 nm
Typical 3dB Optical Bandwidth
Table 136 lists the minimum optical requirements for Multimode and Single
Mode glass fiber optic cable used with the Option 11C.
Minimum
200
Note: The typical power budget for the glass fiber link is typically 8 dB.
The fiber link is limited to a maximum length of 3 km, even though with
many optical cables the optical power budget of 8 dB could support
greater lengths. To guarantee reliable operation a bandwidth of 150%
should be maintained. If the link is increased beyond the 3 km length the
150% margin is deteriorated possibly resulting in link malfunction under
some conditions.
