Typical distances listed are based on the follow-
ing assumptions for system loss. As actual losses
vary from one installation to another, the distance
NOTE
covered by your system may vary.
CONNECTOR LOSSES (TOTAL OF BOTH ENDS)
ST connector 2 dB
FIBER LOSSES
820 nm multimode 3 dB/km
1300 nm multimode 1 dB/km
1300 nm singlemode 0.35 dB/km
1550 nm singlemode 0.25 dB/km
Splice losses: One splice every 2 km,
at 0.05 dB loss per splice.
SYSTEM MARGIN
3 dB additional loss added to calculations to compensate for
all other losses.
Compensated difference in transmitting and receiving (channel
asymmetry) channel delays using GPS satellite clock: 10 ms
AMBIENT TEMPERATURES
Storage temperature: –40 to 85°C
Operating temperature: –40 to 60°C; the LCD contrast can be
impaired at temperatures less than –
20°C
HUMIDITY
