Why are most optical modules LC ports

LC connectors allow manufacturers to double port density compared to SC, FC, or ST ports. In a world where servers deploy 25G/100G/400G links at scale, density is everything. Most SFP fiber optic modules use LC connectors, while SC connectors are mainly found in legacy networks and MPO/MTP connectors are used for high-density cabling rather than directly...
