Frequently asked questions5 questions
What does the TP-Link SM321A do?
It is a 1000Base-BX bi-directional WDM SFP module that carries Gigabit Ethernet over a single strand of single-mode fibre. It transmits at 1550 nm and receives at 1310 nm, and it uses an LC simplex port.
Does the SM321A need to be paired with another module?
Yes, it works with the TL-SM321B as a pair. Because it sends on 1550 nm and receives on 1310 nm, the matching module at the other end of the link handles the opposite wavelengths.
What fibre type and distance does it support?
It uses 9/125 μm single-mode fibre. The maximum cable length is 20 km, and the data rate is 1.25 Gbps in line with IEEE 802.3z.
Can I fit or remove it while the switch is powered on?
Yes, the module is hot-swappable. It follows the SFP-MSA standard and supports Digital Diagnostic Monitoring (DDM), and it runs from a 3.3 V supply.
What operating conditions is it rated for?
It operates at 0–70 °C and 10–90% RH, non-condensing. Storage is rated at -40–85 °C and 5–90% RH, non-condensing. The module measures 55.4 x 14.6 x 12.9 mm.
