Hardware Installation
Connect the Fiber Port (ES8508F)
Connect the fiber port to another fiber Ethernet device using the following diagram. An improper connection
will cause the fiber port to not work properly. The fiber port is a standard or square connector (SC). Make sure
that the fiber mode of the cable matches the fiber mode of the ES8508F (Single-Mode or Multi-Mode).
The fiber connector is a standard connector or square connector (SC).
Note: 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 to 5km.
IEEE organization recommends maximum optical fiber cable distances as defined in the following table.
