Cabling - Korenix JetNet 3008f v3 User Manual

4-5. Cabling

The UTP cable connection between the JetNet 3008 and the attached
devices (switches, hubs, workstations, etc.) must be less than 100 meters
(328 ft.) long.
The transmission distance of JetNet 3008f is depends on the type of fiber
transceiver model and the attenuation of optical fiber cable. The following
information is fiber transceiver specification of JetNet 3008f series. Please
ensure the cable attenuation between two far end nodes is less than the
power budget of fiber transceiver. Table-3 shows the specification of
optical fiber transceiver JetNet 3008f used.

Note:
1. In the IEEE standard, it suggests the available transmission distance is 2KM for 62.5/125um
fiber optical cable in 1310nm wave length. Actually, the attenuation of multi-mode 62.5/125um
optical fiber cable is 1.5dBm/KM and the maximum link distance can up to 4~5km.
2. IEEE organization recommends maximum optical fiber cable distances as defined in
the table-4 shows as below:
