A.2 10Base-FL MULTIMODE FIBER REQUIREMENTS
When you connect a 10Base-FL Multimode Fiber segment to the
EMC38-12, the device at the other end of the fiber segment must meet
IEEE 802.3j 10Base-FL specifications. Your 10Base-FL Multimode Fiber
segment must meet the following requirements.
Segment Length
The IEEE 10Base-FL standard requires that devices be able to transmit
from 0 to at least 2000 meters (6561 feet) per segment of fiber optic cable.
Optical Connector Insertion Loss
The 10Base-FL standard was developed on the basis of a maximum
insertion loss of 1 db.
Segment Insertion Loss
The optical insertion loss of 10Base-FL segments shall be less than
12.5 db, measured using an optical signal source with a center wavelength
of 850 nm and a spectral width of 75 nm.
Attenuation
The 10Base-FL standard was developed on the basis of attenuation values
of less than or equal to 3.75 dB/km, when measured at a wavelength of
850 nm with 62.5/125
µm fiber.
