Patch Card for ONT OLT (SC to SC)

Selecting the correct patch cord for your Optical Network Terminal (ONT) and Optical Line Terminal (OLT) is crucial for maintaining a high-performance fibre optic network. For EPON/GPON ONUs, the choice between SC/APC and SC/PC connectors depends on the interface of the ONU. Most China OEMs opt for SC/PC optical interfaces for their ONUs/ONTs, which necessitates using SC/PC patch cords. However, if the product includes CATV service, it will have an SC/APC interface, requiring an SC/APC patch cord. Matching the patch cord with the ONU’s optical interface is important to avoid high insertion loss and ensure optimal performance. The colour coding—green for SC/APC and blue for SC/PC—can help identify the correct type. Using the right patch cord is essential for reliable and efficient data transmission for any network setup.
