1000 Base T-SX/LX
2.1.1 Functions of 100BaseX Port (Fiber Interface)
- Full data rate of 1000Mbps for full duplex operation
- Auto SW on rear panel to enable or disable auto negotiation function as follows:
NON-AUTO Disable auto negotiation function (forced full duplex mode)
AUTO Enable auto negotiation function
Note: For connecting to a 1000BaseX device, which did not provide auto negotiation capability, setting SW to NON-AUTO may prevent unexpected link failure occurrence. In most cases, the AUTO setting will work. With two of these converters at both ends of the fiber connection, set the switch to NON-AUTO (forced full duplex mode) to achieve the best performance.
The following table lists the fiber connectors, fiber cables and the maximum length supported by each converter model:
|Model||Fiber||Wavelength||Output Power||Input Sensitivity|
|M7254||SX||850nm||-9.5 ~ -4dBm||-12.5dBm max.|
|M7255||LX||1310nm||-9.5 ~ -3dBm||-14.4dBm max|
|Model||Fiber Used||Cable Length|
|M7254||MM 62.5/125µm||220 meters|
|MM 50/125µm||500 meters|
|M7255||SM 9/125µm||10 km|
|M7255-4||SM 9/125µm||40 km|
|PWR||Power status||ON||Power on|
|TP-LINK||UTP link status||ON||TP link up|
|OFF||TP link down|
|TP FDX||UTP duplex status||ON||TP Full duplex|
|OFF||TP Half duplex|
Collisions on half-duplex
|TP-RX||UTP Rx status||ON||TP Reciever in operation|
|OFF||TP no receiving operation|
|TP-TX||UTP Tx status||ON||TP Transmitter in operation|
|OFF||TP no transmission|
|FBR-LNK||Fiber Link Status||On||Fiber Link up|
|OFF||Fiber Link down|
The DC input of the converter is:
|DC Input Jack|
|DC input rated voltage||+5VDC|
|DC input voltage range||+4.75 ~ 5.25VDC|
|DC power consumption||max. 0.8A @+5V (4 Watts)|
|DC input Jack|
Before you begin the installation, check the AC voltage of your area. The AC power adapter, which is used to supply the DC power for the unit, should have the AC voltage matching the commercial power voltage in your area.
The specifications of the AC power adapter are:
|AC input power||AC power voltage of your area|
|DC output power||+5V minimal 1.5A|
Steps to apply power are:
1. Connect the power adapter DC plug to the DC input jack located on the back of the converter before connecting to the AC outlet
2. Connect the power adapter to the AC outlet
3. Check power LED indication
The figure below shows the configuration used when connecting to an auto-negotiation device and a non-auto-negotiation device.
For proper communications, the UTP connections on both ends must be in the same configuration, either 1000M full duplex or 1000M half-duplex. Set the Auto SW to NON-AUTO mode to use forced full duplex mode for the fiber connection.
