ISM321A-20 - TP-Link 1000Base-BX WDM Bi-Directional Industrial SFP Module
Description
Description
The TP-Link ISM321A-20 is a 1000Base-BX WDM Bi-Directional Industrial SFP Module designed to deliver gigabit fibre connectivity over a single strand of single-mode fibre. Using wavelength-division multiplexing (WDM), 1000BASE-BX carries traffic in both directions on one fibre, which makes it a practical choice wherever only one fibre is available. Built for tougher environments than standard modules, the ISM321A-20 supports an industrial operating temperature range of -40 to 85°C, and reaches distances of up to 20 km.
TP-Link positions its industrial SFP lineup, which includes the ISM321A-20 and ISM321B-20, for factory, outdoor and transportation deployments. If you are extending a network across a site, a plant or a remote location, the SKU ISM321A-20 offers a reliable way to do it with less fibre.
