Keep Perle converter and switch links on fiber with a compact SFP module built for straightforward deployment. The PSFP-100D-M2LC05 supports 100 Mbps Ethernet over single-mode fiber and uses an LC connector, giving network teams a clean fit for point-to-point connections where distance and signal integrity matter. This module is suited to environments that need a dependable optical uplink without moving to a higher-cost transceiver class. Its 5 km reach supports distributed closets, campus edges, and building-to-building runs where copper is not the right medium. The small form factor helps preserve port density while keeping the installation familiar for teams already working with Perle platforms. For infrastructure buyers, the value is in matching the transceiver precisely to the application: enough distance for real-world access links, the right connector for standard fiber terminations, and a Perle-compatible design intended for converter and switch integration. That combination helps reduce overbuying while keeping the network architecture clean and serviceable.
