Used in pairs, this media converter can extend distances between two twisted pair switches or a switch and a server up to 120 km over single mode fiber. Using one media converter, a switch with a copper port can be connected to a switch with an existing fiber interface.
Auto-negotiation allows devices to perform automatic configuration to achieve the best possible mode of operation over a link. Devices with this feature will broadcast their speed to other devices and negotiate the best mode of operation between the two devices.
AutoCross automatically detects and configures the twisted pair port on the converter to the correct MDI or MDI-X configuration.
Link pass through
Link pass through is a troubleshooting feature that allows the media converter to monitor both the fiber and copper RX ports for loss of signal. In the event of a loss of RX signal on one media port, the converter will automatically disable the TX signal of the other media port, thus "passing through" the link loss.
Far End Fault (802.3u)
Far End Fault (FEF) is a troubleshooting feature that is generally used in conjunction with link pass through to notify both end devices of a loss of link. In the event of a loss of the fiber RX signal on the far end converter the converter will automatically generate a Far End Fault signal and send it on its TX fiber port to notify the near end converter of a fiber link loss.
Automatic link restoration
Automatic link restoration on Transition Networks' products allows users to continue using link loss notification feature activated in both directions. Many competitive solutions allow for link loss notification activation only in one direction. If link loss feature is activated in both directions, competitive products are put in a "deadly embrace" and they cannot restore the link without resetting the converters.
Pause (IEEE 802.3xy)
Pause signaling is an IEEE feature that temporarily suspends data transmission between two devices in the event that one of the devices becomes overwhelmed. In the event that a device needs some time to clear network congestion, it will send out a pause signal to the other end device, which will then wait a pre-determined amount of time before re-transmitting the data.
Single fiberProduct Highlights
Single fiber technology offers a 50% savings in fiber utilization. It is an attractive solution to maximize the usage of a limited number of fiber runs.
- Operates under heavy traffic loads without excess heat
- Round trip delay of only 40 bit times
