GT-1205A

10/100/1000BASE-T to Dual 100/1000BASE-X SFP Media Converter

PLANET GT-1205A Gigabit SFP Media Converter is upgraded by providing dual SFP

slots; accept 100FX or 1000X SFP module, and other features shown below:

■ DIP Switch for 100FX or 1000X SFP module supports on dual SFP slots

■ DIP Switch for 3-port Operation in Gigabit Switch Mode or Redundant Mode

■ Redundant Hardware Fiber Port

Highly Convenient and Distance Extendable

The GT-1205A is 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. The GT-1205A provides high reliability and flexibility to extend the media

transmission distance up to 550m or 2km (multi-mode fiber) and 10km or longer

20/40/80/120 kilometers (single-mode ber or WDM ber), depending on the optional

100/1000BASE-SX/LX SFP modules.

Standard

• Complies with IEEE 802.3 10BASE-T

• Complies with IEEE 802.3u 100BASE-TX/100BASE-FX

• Complies with IEEE 802.3ab 1000BASE-T

• Complies with IEEE 802.3z 1000BASE-SX/LX

• IEEE 802.3x full-duplex ow-control, back-pressure in

half-duplex eliminate packets loss

Interface

• Dual 100BASE-FX/1000BASE-SX/LX SFP ber-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

Redundancy

• Link status auto-detecting and redundant on dual ports

with the same connector type

• Allows only the Primary-Port or the Backup-Port to

activate at a time

• When the Primary-Port link fails occurs, the tra󰀩c swaps

to Backup-Port automatically

• Once the Primary-Port link regains, the tra󰀩c swaps from

the Backup-Port to the Primary-Port

• Hardware ber port redundant

Mechanical

• External 5V/2.5A DC power supply

• LED indicators for easy network diagnose

• DIP switch for 100FX or 1000X SFP module supports

on dual SFP slots

• DIP switch for 3-port operation in 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

GT-1205A Applications Gigabit Ethernet Distance Extension The GT-1205A directly converts the media from the Gigabit fiber to twisted pair interface. For example, it can be applied between the Gigabit Fiber Switch and the Gigabit Copper Network Card to perform media conversion and transmission. With the conversion, you can easily have the transmission distance of Gigabit copper cable extended up to 550 meters or longer (depending on SFP module).
