LE1422C is a multi-mode fiber optic 4-port module equipped with a small-form-facto
MTRJ-type connector. It looks almost like | 100BASE-FX MTRJ | | | |
an RJ-45 port, but it is black in color. The | | | | Connectors | 1 |

The functionality of this 100BASE-FX multi-mode 4PM is same as the ST and SC- types, and it is equipped with the same ACTIVITY (ACT), LINK (LK) LEDs to indicate proper connectivity with the remote device and (FDX/HDX) indicate the FULL OR HALF DUPLEX MODE at the port. It has the same “100Mb FX” lettering on the faceplate. Note tha the other end of the fiber cable may have a different connector, not necessarily an M T-RJ type.
