155M SFP Transceivers

The 155M SFP (Small Form-factor Pluggable) transceiver family provides reliable optical connectivity for SDH/SONET (STM-1/OC-3), Fast Ethernet, and other legacy applications. Available in duplex, single‑fiber BiDi, and wavelength‑division multiplexing (CWDM/DWDM) options.

Common Features

  • 155Mbps data rate (STM‑1/OC‑3)
  • SFP MSA compliant
  • Hot‑pluggable, LC duplex / Simplex LC
  • Digital diagnostics monitoring (DDM)
  • Wide operating temperature (-40~85°C industrial options)
  • RoHS compliant
