Gigabit Copper-to-Fiber Converter

The PLANET GT-1205A connects one 10/100/1000Base-T copper port to two 1000Base-X SFP slots. It serves network engineers extending Ethernet over fiber in campus or metro links. The unit also slides into MC-700 or MC-1500 chassis for centralised management. It is not suited for deployments that require copper-only aggregation or PoE injection.

Thermal and Power Profile

The converter draws 5.4 watts maximum from a 5V DC, 2A supply, producing 18.5 BTU per hour. It operates silently with no moving parts across 0 to 50 degrees Celsius ambient. Storage tolerance reaches -10 to 70 degrees Celsius at 5 to 95 percent relative humidity non-condensing. No active cooling or acoustic planning is needed.

Upgrade Path and Fit

The GT-1205A replaces single-SFP media converters when a redundant or dual-fiber uplink is required. The DIP switch selects three-port switch mode or redundant mode to minimise packet loss via IEEE 802.3x flow control. The jump is worthwhile when link resiliency or chassis density outweighs the cost of a basic unmanaged converter.

Questions about this item

How do I install the GT-1205A in a Planet MC-700 or MC-1500 chassis?

Slide the unit into an open bay until it locks; the chassis backplane supplies 5 V DC power so no external adapter is needed.

What ongoing maintenance does the GT-1205A require?

Keep ventilation clear and operate between 0 and 50 °C; clean LC fiber connectors with a lint-free swab if signal loss appears.

What is the first limit reached under sustained full-speed traffic?

The single 10/100/1000Base-T copper port caps total throughput at 1000 Mbps even though two SFP slots are present.
