General MPX
Connector to
Optical Fiber
Port
Assignment
The following diagram details the MPX connector fiber port assignments and MPX connector housing position. It describes
the cables and which fibers are used for the various cards. Depending on the cable type, use either the fiber position number or
multi-color code scheme and the receive (RX) and transmit (TX) indicators to clarify the optical fiber assignment. The MPX
housings and connectors are marked with a white stripe reference marker to properly orient the MPX connectors.
Important:
(SONET network only) For DCS application 2-port OC-48/STM-16 fiber optic connection options, see
Application MPX Optical Connector Scheme
