Overview

Product details

Overview

The FT-1-25G-550M-3 is a 1.25 Gbps multimode 1x9 transceiver fitted with an ST bayonet connector, a natural fit for legacy multimode plants built on ST patching. Two wavelength options cover short reaches: 850 nm for up to 550 meters and 1310 nm for up to 2 km. The module works from either a 3.3 V or 5 V supply with an LVTTL/TTL signal interface, matching both new and older 1x9 host designs. Commercial (0 to 70 ℃) and industrial (-40 to 85 ℃) temperature grades are available, and a metal shield housing addresses EMC Class A requirements.

Key Features

  • 1.25 Gbps duplex transmission over multimode fiber
  • Two reach options: 850 nm for up to 550 m, 1310 nm for up to 2 km
  • ST bayonet connector, a natural fit for legacy ST patching plants
  • Dual supply: 3.3 V or 5 V, with LVTTL/TTL signal interface
  • Commercial (0 to 70 ℃) and industrial (-40 to 85 ℃) temperature grades
  • Metal shield housing, EMC Class A design

Applications

  • Legacy enterprise LAN upgrades over ST patching
  • Gigabit Ethernet building and campus links
  • Industrial networks and 1x9 equipment maintenance
