GT-1205A – Planet 1-Port Gigabit Ethernet + 2-Port Gigabit SFP Switch Media Converter

Available on backorder

Part Number:GT-1205A

$194.00 (ex-GST)

Equipped with one 10/100/1000BASE-T port and dual SFP slots to support conversion between 10/100/1000BASE-T and 100/1000BASE-X network. The dual SFP slots make the Ethernet signals connect easily and efficiently by adding single-mode or multi-mode media modules or the combination of both types. With an emphasis on high reliability and flexibility, it can extend media transmission up to a distance of 550m or 2km (multi-mode fiber) and 10km or longer 20/40/80/120 kilometers (single-mode fiber or WDM fiber), depending on the optional 100/1000BASE-SX/LX SFP modules.


  • Complies with IEEE 802.3 10BASE-T
  • Complies with IEEE 802.3u 100BASE-TX
  • Complies with IEEE 802.3ab 1000BASE-T
  • Complies with IEEE 802.3z 1000BASE-SX/LX
  • IEEE 802.3x Full-duplex Flow-Control, Back-Pressure in Half-duplex eliminate packets loss


  • Dual 1000BASE-SX/LX SFP fiber-optic slots
  • One 10/100/1000BASE-T Copper, auto MDI/MDIX function
  • Auto-Negotiation for 10/100/1000BASE-T; Half-duplex or Full-duplex for 10Mbps and 100Mbps, Full-duplex for 1000Mbps
  • Supports maximum frame size up to 10K jumbo packet size
  • IEEE 802.1Q Tag VLAN Transparent, Multicast pass-through


  • Link status auto-detecting and redundant on Dual ports with the same connector type
  • Allows only the Primary-Port or the Backup-Port active at a time
    - When the Primary-Port link fail occurs, the traffic swaps to Backup-Port automatically- Once the Primary-Port link regains, the traffic swaps from the Backup-Port to the Primary-Port
  • Hardware fiber port redundant


  • External 5V/2.5A DC power supply
  • LED indicators for easy network diagnose
  • DIP switch for 3-port operation with Gigabit switch mode or redundant mode
  • Compact in size, easy installation
  • Co-works with PLANET 10”/19” Media Converter Chassis (MC-700/MC-1500/MC-1500R/MC-1500R48)
  • Wall mounting and DIN-Rail installation supported
