high performance and long life.
• Do not pull or kink patch cords, as the glass strand in the middle might
become damaged or broken.
• A sharp bend will cause excessive signal loss.
• Keep patch cord bend radiuses no less than an inch.

There are several types of
optical connectors in use today.
This figure shows the two most
popular for Ethernet, SC and
LC.
SC to LC Cable
This is a duplex multi-mode LC cord.
