T1/E1 Networks
The T1/E1 Copper to Fiber Media Converter enables the deployment of fiber into campus or industrial environments; allowing network distances of up to 15,000 meters. This deployment of fiber into these environments provides a cost-effective solution and allows for the standardization on fiber as a media type. This is especially significant in industrial environments where fiber is immune to electrostatic interference "noise."
Features (back to top)
•
 Converts the copper ports on T1/E1 devices, such as a PBX or T1/E1 Router, to multimode or single mode fiber.
•
 Extends distances 2,000 meters over multimode fiber or 15,000 meters over single mode fiber.
•
 Switch selectable RJ-45 connectors for T1 or E1.
•
 Jitter attenuators optimize Bit Error Rate (BER) performance.
•
 Loopback switch facilitates installation.
•
 Network debug procedures make BER testing more convenient.
•
 Built-in troubleshooting with the addition of a selectable TAOS (Transmit All Ones) switch on the fiber and copper interfaces allows the network engineer to test all T1/E1 equipment on that network segment and ensure the network link.
•
 Dry relay contacts enable the media converter to be tied into a separate alarm circuit commonly found in a T1/E1 environment. Contacts will be activated on loss of power or loss of fiber link.
•
 An LED provides Alarm Indication Signal (AIS) indication.
Applications (back to top)
Extend Network Distances:
Extend distances over 2,000 meters using 850nm optics and multimode fiber, and 15,000 meters using 1310nm optics and single mode fiber.

Provide Campus Interconnects:
With the exceptioin of Ethernet, T1/E1 is one of the most common campus/metropolitan area networking interconnects. A copper to fiber conversion on the premise side of the T1/E1 makes it easier to integrate voice traffic, frame relay or IP type traffic on your fiber network.
