Which device should the optical module be plugged into
Optical modules can either plug into a front panel socket or an on-board socket. 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. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. The QSFP-DD, QSFP, and SFP transceiver modules are hot-swappable and connect the electrical circuitry of the system with an optical external network. The following figure shows the QSFP-DD transceiver, but the procedures outlined in this document apply to all pluggable transceivers. To aid in the task of choosing the right transceivers for your network, here are 6 key factors that should be reviewed with a transceiver/networ system specialist before making your final selections. These technical and operational.
