The TP-Link SM321A is a Gigabit WDM SFP transceiver designed to provide reliable fibre connectivity over a single fibre strand. Working alongside the matching SM321B module, it offers a cost-effective solution for extending network links while reducing fibre cabling requirements.
Supporting Gigabit Ethernet speeds, the SM321A delivers stable, high-performance data transmission for business networks, campus environments, and building-to-building connections. Its compact SFP form factor enables easy installation in compatible switches, routers, and media converters.
With hot-swappable support, the SM321A can be installed or replaced without disrupting network operation. It provides a practical and efficient way to expand fibre networks while maximising existing infrastructure and minimising deployment costs.
