Gigabit Based AC220V Fiber Media Converter
Overview
- Olycom OM330-GE series Gigabit Ethernet SFP fiber media converters bridge the gap between copper and fiber infrastructures.
- Link fault pass through (LFPT)
- The SFP fiber media converters are designed for maximum convenience for fiber to copper Ethernet conversion applications
- 10K super data packet transmission
- By simply changing the hot-plug-and-play SFPs, flexibility in transmission rates, working distances, and fiber network types can be realized
What is Link fault pass through (LFPT) ?
Link Fault Pass-Through (LFPT) is a network technology feature used in Ethernet and fiber optic communication systems.
What it does
LFPT automatically propagates a link failure signal from one end of a network segment to the other. When a fault or link-down event is detected on one side of a device (like a media converter or switch), LFPT notifies the other side by bringing down its link as well.
Why it matters
Without LFPT, a device connected to a media converter might not realize there's a break in the network path, because its local link light still shows "up." This can cause:
- Traffic being sent into a broken path (black-holing)
- Failover mechanisms not triggering properly
- Delayed fault detection
With LFPT enabled, the fault is immediately visible end-to-end, allowing:
- Faster failover to redundant paths
- Accurate link state monitoring
- Proper operation of spanning tree and other protocols
Where it's commonly used
- Media converters (e.g., copper-to-fiber converters) — the most common use case
- Ethernet extenders
- WAN/carrier Ethernet equipment
- Industrial networking devices
Example scenario
[Switch A] ←copper→ [Media Converter] ←fiber→ [Media Converter] ←copper→ [Switch B]
If the fiber link breaks, LFPT causes both media converters to drop their copper-side links, so Switch A and Switch B both see a link-down event and can react accordingly (e.g., activate a backup path).
In short, LFPT ensures link failures are transparent and propagated across network boundaries where they might otherwise be hidden.
