8 Port Ethernet Smart Switch With Fibre Uplink

Fibre Uplink Port Specifications

The switch has a 100Base-FX optical fibre uplink port that operates at the 1310nm optical wavelength for both the multimode and singlemode models.

The fibre size used for multimode links is 50/125 or 62/125 micron. The fibre size used for singlemode links is 8/125 or 9/125 micron.

The maximum distance between any two fibre optic devices is determined by a number of factors including optical link loss, the type and number of patch cords and joints in the link, the launch power of the transmitter and the sensitivity of the receiver. These variables make calculating the maximum working distance between two converters quite difficult and so it is best to design networks using optical loss budgets rather than using just working distance.
