NOTE:
To be eligible for support by Harmonic, use qualified SFPs only.
An optical SFP has two LC sockets, Receive(Rx) and Transmit(Tx). Use Multimode or
Singlemode fiber optics to connect your Gigabit Ethernet switch to the Rx socket. If bi-
directional topology is used, connect the Tx socket back to the switch.
