3.3.1 10BASE-FL
The 8829 Media Converter 10BASE-FL Transceiver
features a minimum loss budget of 15.5dB.
The general rule when figuring total link loss is
to allow 0.5dB per connector (devices and patch
panel connections) plus 4dB per km attenuation on
62.5/125 micron cable.
3.3.2 Single Mode 1310nm Laser
The 8829 1310nm Laser UTP-to-Fiber Optic Media
Converter features a HI and LO power setting to
prevent overdriving the cable on shorter cable
lengths. In general, the LO setting should be used
for applications with a total link loss of approxi-
mately 9dB or less.
With the HI OPT PWR feature set, the 8829 Me-
dia Converter yields a minimum loss budget of 20dB
for the standard version and 25dB for the Extended
version.
It should be noted, however, that if the full single
mode HI PWR loss budget is used in a Half-Du-
plex (CSMA/CD) application, there is a strong
probability that the IEEE 802.3 Propagation De-
