OptEnet Media Converter with SFP modules support Medium Dependent Interface Crossover
(MDI-X). OptEnet Media Converter Module Ethernet ports allow connections to other hubs or
switches without a null-modem or crossover cable. If a null-modem or crossover cable has been
used the OptEnet Media Converter with SFP module automatically detects this and switches the
contacts to match the other end.
Any blinking of a link LED indicates auto-negotiation in process. If a link LED continues to
blink for more than 30 seconds then the operation of the far end device (i.e., duplex and speed)
needs to be verified or changed.
5.1 10/100 Mb/s Module
If the PC workstation port has been set to auto-select (i.e., full auto-negotiation) for speed and
duplex, the TPLink LED will be OFF when power is applied unless a valid optical link has
already been established with a remote optical port. If a valid optical link has been established,
FOLink LED will be YELLOW for 10 Mb/s operation or GREEN for 100 Mb/s operation. The
preferred mode of operation for the port is auto select for both speed and duplex. This will
insure that a link can be established regardless of the far end operational mode.
OptEnet 10/100BaseLX Media Converters support auto-negotiation as defined in TIA/EIA-785.
Auto-negotiation allows the unit to automatically select the highest performance level for
COPPER or FIBER.
5.2 1000 Mb/s Module
Set data rate speed to 1000 Mb/s and enable half/full duplex auto-negotiate on any equipment
connected to the OptEnet 1000 Mb/s Media Converter module.
If the Network Interface Card (NIC) or port in the PC workstation has been set to 1000 Mb/s for
speed and half/full duplex auto-negotiate, the link LED will be OFF when power is applied.
Once valid optical and electrical links have been established, link LEDs turn GREEN.
6 OPERATION
The Module may be controlled through a Command Line Interface. Refer to the OptEnet Media
Converter Communications User Manual listed in
Related Publications , for operational
procedures that pertain to the CPU module.
7 MAINTENANCE
Follow standard cleaning practices for maintenance of fiber adapters and connectors.
