The optical module serves as a crucial component in optical fiber communication systems, operating at the physical layer, which is the lowest layer in the OSI model. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa. This gives you fast and steady data transfer. It also cuts down on signal loss or interference.
Connect one end of the optical fiber to the optical module and the other end to the remote device. A link's transmit signal (Tx) must match its corresponding receiver (Rx) at the other end. Although it may seem obvious, fiber optic polarity is a frequent source of confusion and. This section describes how to install optical transceivers on the SFP or SFP+ ports and connect them to the ports of the peer device using optical fibers according to the network plan. The USG supports both 1 Gbit/s, 10 Gbit/s, and 40 Gbit/s optical modules. If a connector is used, the two fibers can later be disconnected for testing or to change the routing of the cable, while splicing is permanent.
