In the rapidly developing field of optical communication today, multimode dual core LC fiber patch cords are gradually becoming the mainstream choice for data centers and large enterprise networks due to their unique advantages and performance. However, how to utilize this high-performance fiber optic jumper to achieve efficient and stable data transmission is currently a major challenge. This has led to controversy over the selection of optical module schemes.

Among numerous optical module schemes, SWDM (Wavelength Division Multiplexing) scheme has received widespread attention due to its simple and efficient characteristics. This scheme mainly utilizes VCSEL/PD in four different wavelength bands of 850nm (850nm, 880nm, 910nm, 940nm) for combining and splitting. Although the principle is simple, this solution requires a high demand for the supply chain of optical chips and requires a stable supply chain to ensure the implementation of the solution.

Another solution is the SR2 BIDI solution. This scheme utilizes DSP (PHY) to speed up 4x25Gbps electrical signals to 2x26GBd electrical signals. After photoelectric conversion, Bi Direction bidirectional transmission is carried out using 850/910nm VCSEL/PD. This solution can achieve high-speed bidirectional data transmission, but it also requires high equipment and technology requirements.

In practical applications, the selection of optical module schemes needs to consider multiple factors. This includes but is not limited to data transmission rate, stability, device compatibility, cost, etc. The SWDM scheme and SR2 BIDI scheme each have their own advantages and disadvantages, and they need to be selected according to actual needs.

Overall, the application of multimode dual core LC fiber jumpers has brought new possibilities to the field of optical communication, and the selection of optical module solutions is crucial. Only by deeply understanding the characteristics and application scenarios of various solutions can we make the best choice and achieve high-speed, stable, and efficient data transmission.
