Overview

Product details

Overview

The FT-SFPPLUS-1-25G is the base part number for the F-tone Networks 1.25 Gbps SFP optical transceiver family, covering everything from short multimode patching to long single-mode spans. The FTSPD series table below lists the optical variants: an 850 nm VCSEL version for 0.5 km multimode links, 1310 nm FP versions for 10 km and 40 km single-mode links, and 1550 nm DFB versions for 40 km, 80 km and 120 km spans, plus RJ45 copper versions for 10/100/1000M twisted-pair connections. All variants share the hot-pluggable SFP footprint, a single 3.3 V supply, digital diagnostic monitoring support, and a lead-free RoHS-10 compliant build with an all-metal housing for EMI performance.

Key Features

  • 1.25 Gbps SFP family: 850 nm VCSEL to 1550 nm DFB optical options
  • Reach options from 0.5 km multimode to 120 km single-mode
  • Duplex LC connector on optical variants; RJ45 on copper variants
  • Digital diagnostic monitoring (DDM) support
  • Single 3.3 V power supply; RoHS-10 compliant, lead-free
  • All-metal housing for EMI performance

Applications

  • Gigabit Ethernet access and aggregation networks
  • Enterprise and campus fiber backbones
  • Telecom transport and industrial Ethernet links
