Description

The TP-Link TL-SM321A (model SM321A) is a 1000Base-BX WDM bi-directional SFP module. It carries Gigabit Ethernet traffic over a single strand of single-mode fiber, using a data rate of 1.25Gbps and an LC Simplex connector.

The module transmits at 1550 nm and receives at 1310 nm, and it supports a maximum distance of 20 km on 9/125 μm fiber. It follows IEEE 802.3z and SFP-MSA, supports DDM, and can be hot swapped.

Key features:

  • 1000Base-BX standard with WDM BiDi single-fiber link technology
  • Data rate of 1.25Gbps, with port speed of 10/100/1000 Mbps
  • TX wavelength of 1550 nm and RX wavelength of 1310 nm
  • Single-mode fiber with 9/125 μm core, LC Simplex connector, up to 20 km
  • DDM/DOM support, SFP-MSA compliance and Hot Swappable design
  • 3.3V power supply, laser maximum output power of 0.501 mW (-3 dBm)
  • Operating temperature of 0 … +70 °C (32 … 158 °F) and dimensions of 55.4 × 12.9 × 13.7 mm (2.18 × 0.508 × 0.539 in), with FCC and CE marks
