Do optical modules need to be used as a set
There have been multiple variants of the electrical interface of optical modules that have been used over the years. The earliest forms of optical modules had an analog electrical interface. In the transmit direction, the optical module would directly drive the laser or LED with the analog signal coming from the front system card. In the receive direction, the module would directly drive the receive electrical interface with the o.

Optical modules in the telecom room emit light
At the heart of every optical transceiver lie three essential components, often called the “Three Pillars” of optical communication: Laser — generates light. Modulator — encodes data onto the light. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa. fibers to accommodate the high volume of global network trafic. Deployed across fronthaul, midhaul, and backhaul. Optical data transmission uses transmitter devices for sending digital signals in the form of light — typically, it sends near- infrared light into an optical transmission fiber (telecom fiber) or into free space (→ free-space optical communications).

How to connect multimode modules and fiber optic cables
Most modern fiber-enabled network switches require an SFP transceiver module featuring a duplex (two strand) multimode OM3 or duplex single mode OS2 connection with LC connectors. Direct attach cables with pre-terminated SFP connections may also be used. Fiber provides: Increased internet signal bandwidth. It is possible to connect the two different cable types; however, a media converter must be used to adapt the core sizes and optical.
