Optical Connections

PRIMARY OPTO OUT

Connector ............................................LC/PC
Primary Optical Launch Power ............-5dBm
Wavelength..........................................1310nm
Optical Fibre ........................................Multimode 50/125 or 62.5/125**

PRIMARY OPTO IN

Connector ............................................LC/PC
Primary Optical Sensitivity...................-22dBm
Wavelength..........................................1310nm
Optical Fibre ........................................Multimode 50/125 or 62.5/125**

**Note: the transmission distance is limited by the bandwidth of the Multimode optical fibre. The optical
data rate is 1.25Gbits/s. The maximum bandwidth specification at this data rate for Multimode fibre is
2km. although in most cases the units will operate successfully over longer fibre lengths. It is
advisable however for distances greater than 2km, to have the optical fibre tested.
