Note:

1.Do not touch the output pins on the transceiver with your hand.

2.Always keep the protective dust plug on the SFP’s optical bores until you are ready to make a connection.

Caution:

DO NOT point or stare directly into the beam or into the optical port of the transceiver when it is operating, as this can injure your eyesight.

Connection

Use only the TL-SM321A&TL-SM321B together, and TL-SM321A-2&TL-SM321B-2 together for fast and reliable connectivity between switches.

For simplicity, we will take TL-SM321A&TL-SM321B as an example.
