Brief introduction
Thanks for purchasing ATOP’s Fast Ethernet optical transceiver.
This product supports IEEE802.3U 100Base-Tx/Fx protocol, as
well as half and full duplex mode. This manual refers to adaptive
10M/100M transceivers.

Installation
1. RJ-45 interface
The transmission media adopts CAT5 twisted-pair with typical
length of 100 meter. It features the function of Auto MDI-MDI-X
for automatically identifying strait or cross cable.
2. Fiber interface
SC fiber interface is of duplex mode type, including two
interfaces, tagged as TX and RX. When the two sets of optical
transceivers are interfaced or connected to a switch with fiber
interface, the fiber should be in cross connection mode, "TX-RX",
"RX-TX".
3. Connection
Connect the network device (work station, hub or switch) to the
optical transceiver using RJ-45 twisted-pair. Connect the
multi/single mode fiber to the SC/ST fiber interface of the optical
transceiver. Turn on the power. The corresponding LED will turn
on to indicate connection. (Please refer to the table below).
