Description

The TP-Link TL-SM321B (model SM321B) is a 1000Base-BX WDM bi-directional SFP module with an LC Simplex connector. It carries data in both directions over a single single-mode fiber, using a 1310 nm transmit wavelength and a 1550 nm receive wavelength.

The module runs at a data rate of 1.25Gbps and supports a maximum distance of 20 km. It follows IEEE 802.3z and supports DDM, SFP-MSA and hot swapping, and it works with a 3.3V supply.

Key features:

  • 1000Base-BX standard with WDM BiDi single-fiber link technology
  • SFP form factor with LC Simplex connector and 9/125 μm single-mode fiber
  • TX wavelength of 1310 nm and RX wavelength of 1550 nm
  • Data rate of 1.25Gbps and maximum distance of 20 km
  • DDM, SFP-MSA and Hot Swappable hardware functions
  • Operating temperature of 0 to +70 °C (32 to 158 °F) and operating humidity of 10-90% RH, non-condensing
  • Dimensions of 55.4 × 12.9 × 13.7 mm (2.18 × 0.508 × 0.539 in), with FCC and CE compliance
