Fiber optic transceivers convert electrical signals to optical signals (and vice versa) for high-speed data transmission over fiber optic cables — the essential interface component in telecom networks, data centers, enterprise switches, and industrial Ethernet systems. Our fiber optic transceiver inventory covers SFP, SFP+, XFP, QSFP, and QSFP28 form factors from Finisar/II-VI, Cisco, Arista, Intel, and HPE — supporting speeds from 100Mbps to 100Gbps, wavelengths from 850nm (multimode) to 1550nm (single-mode), and transmission distances from 100m to 120km.
High-speed 10G/25G/40G/100G SFP+ and QSFP+ transceivers for data center and telecom infrastructure face persistent allocation due to supply chain constraints. Welllinkchips stocks a range of fiber optic transceiver types and can source hard-to-find or discontinued modules for legacy networking equipment and telecom infrastructure maintenance.
