Product Description

From the Manufacturer

Extend network distance in full-duplex networks. Used in pairs, this media converter can extend distances between two twisted pair switches or a switch and a server up to 2 km over multimode fiber or up to 20 km over single mode fiber. Connect remote devices using a single 100BASE-TX-to-FX media converter--a switch with a copper port can be connected to a switch or any other 100BASE-compliant device with an existing fiber interface.

Upgrade twisted-pair networks to fiber and end the problems of difficult installations associated with traditional converters. The "Just Convert-IT" line of media converters is there for when you want an inexpensive, no frills converter that offers the same quality and reliability as our full-featured line of products.

If someone tells you media conversion is a commodity product that anyone can bring to market, they probably haven't looked at the extensive product suite offered by Transition Networks. With the industry's most comprehensive offering of full-featured products, Transition's media converters stand out as "the choice" among industry IT professionals.

Generally, media converters are low-level OSI model devices with no IP or MAC addresses and therefore are transparent to the network. This "transparency" makes them very inexpensive and easy to use, but also can make troubleshooting the network very difficult. In an effort to overcome this difficulty and to make media converters "visible" to network managers, Transition has designed their full-featured products to include the most advanced features on the market today.

AutoCross automatically detects and configures the twisted pair port on the converter to the correct MDI or MDI-X configuration.

• Eliminates an entire category of troubleshooting
• No need to identify cable type (straight-through or crossover)
• No user intervention required to determine correct button / switch settings

Auto-Negotiation (802.3u) 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 (10 Mbps, 100 Mbps, etc.) and duplex (half/full) capabilities to other devices and negotiate the best mode of operation between the two devices.

• No user intervention required to determine best mode of operation
• Optimal link established automatically
• Quick and easy installation

While the inclusion of this feature is beneficial, the ability to disable it is equally beneficial. In the event of a non-negotiating end device trying to connect to a negotiating device, the mode of operation will drop to the least common denominator between the two devices (i.e. 100 Mbps, half-duplex). Disabling this feature gives the user the ability to force the connection to the best mode of operation when trying to link with a non-negotiating device. Most Transition converters with Auto-Negotiation will allow you to disable this feature.
