Compact SFP Transceiver (Dual‑Channel BiDi)

The Compact SFP (CSFP) transceiver integrates two independent bidirectional channels in a standard SFP footprint. Ideal for high‑density applications where fiber pair savings are critical. Each channel supports 20km transmission over single‑mode fiber.

Key Features

  • ▹ Dual independent BiDi channels in one SFP footprint
  • ▹ Data rates: 155M, 1.25G, 2.5G per channel
  • ▹ 20km reach on single‑mode fiber
  • ▹ Wavelength: 1310/1490nm or 1550/1310nm (BiDi)
  • ▹ Hot‑pluggable, 3.3V power supply
  • ▹ Digital diagnostics monitoring (DDM)
  • ▹ RoHS‑6 compliant
