3.2.3Connecting Single-Mode Fiber Optic

When using single-mode fiber cable, be sure to use single-mode fiber port connectors. Single-mode fiber cable has a smaller diameter than multi-mode fiber cable (9/125 microns for single-mode, 50/125 or 62.5/125 microns for multi-mode where xx/xx are the diameters of the core and the core plus the cladding respectively). Single-mode fiber allows full bandwidth at longer distances, up to 70km with the single-mode LC.

3.2.4Connecting Fiber Optic Cable to LC ports

1.Before connecting the fiber optic cable, remove the protective dust caps from the tips of the connectors. Save these dust caps for future use.

2.Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens tissue dampened in alcohol. Make certain the connectors are clean before connecting.

3.Connect the Transmit (TX) port on the Magnum 6KM to the Receive (RX) port of the remote device. Connect the Receive (RX) port on the 6KM to the Transmit (TX) port of the remote device.

While connecting fiber media to LC connectors, simply snap on the two square male connectors into the LC female jacks of the Fiber connector until it clicks and secures.

The LINK LED on the front of the 6KM will illuminate and turn Green, when a proper connection has been established at both ends (and when power is ON in the unit). If LINK is not lit or OFF after cable connection, the normal cause is improper cable polarity. Swap the fiber cables at the 6KM connector and also check the connectivity on the target device to remedy this situation.

Reconfigure or reboot both of the devices if required.

If connected properly, you can check via (MNS-6K) software for verifying the validity of SFF Gigabit ports.
