The standard GDC 6432 dCU/3 has an SFP module slot so that the user can choose their own single or multi-mode module. These modules were often terminated by LC connectors. Due to popular demand it was felt that a more rugged connector was required for the link to the commentary box. This version therefore, includes the Neutrik Opticon Duo fibre connection for a secure fibre link, instead of the SFP slot. This link also provides power from the dCCU/OC base station to the dCU/3OC Commentators' Unit. As the connector is fixed, the SFP module needed to be installed internally, so a single mode module is installed within the unit. All other features of the GDC 6432 dCU/3OC are the same as the standard GDC 6432 dCU/OC. Please click below for details.
