1000BaseT Ethernet Port Connection

1000BaseT data is transmitted on differential TRD+/- signal pairs over copper

wires.

1000BaseSFP Fiber Port

The gigabit Ethernet ports on the IMC-101G are 1000BaseSFP Fiber ports,

which require using gigabit mini-GBIC fiber transceivers to work properly.

Moxa provides complete transceiver models for different distance

requirements.

Multi mode:

1000BaseSX 0 to 500 m, 850 nm (50/125 μm, 400 MHz*km)

0 to 275 m, 850 nm (62.5/125 μm, 200 MHz*km)

1000BaseLX 0 to 1100 m, 1310 nm (50/125 μm, 800 MHz*km)

0 to 550 m, 1310 nm (62.5.125 μm, 500 MHz*km)

Single mode:

1000BaseLX 0 to 10 km, 1310 nm (9/125 μm, 3.5 PS/(nm*km)

1000BaseLHX 0 to 40 km, 1310 nm (9/125 μm, 3.5 PS/(nm*km)

1000BaseZX 0 to 80 km, 1550 nm (9/125 μm, 19 PS/(nm*km)

The concept behind the LC port and cable is quite straightforward. Suppose

that you are connecting devices I and II; contrary to electrical signals, optical

signals do not require a circuit in order to transmit data. Consequently, one of

the optical lines is used to transmit data from device I to device II, and the

other optical line is used transmit data from device II to device I, for

full-duplex transmission.

Remember to connect the Tx (transmit) port of device I to the Rx (receive) port

of device II, and the Rx (receive) port of device I to the Tx (transmit) port of

device II. If you make your own cable, we suggest labeling the two sides of the

same line with the same letter (A-to-A and B-to-B, as shown below, or

A1-to-A2 and B1-to-B2).
