Network media converters Transition Networks

1310 nm TX/1550 nm RX, single fiber, SM, SC to 4x RJ-48 + 10/100BASE-TX, RJ-45 + 6-pin DIN These products offer a low cost transport capability for four T1/E1, one Ethernet, and one RS232 data channel line. The converters provide copper connections compatible with G.703, AMI/B8ZS/HDB3, 10/100BASE-TX, as well as RS232 channel; while the optical connection will run at 155Mbps. TDM traffic is not mapped to Ethernet. A hardware-based solution guarantees the constant bit rate of TDM transport without requiring traffic management. The product provides physical layer status monitoring and alarm classification functions for Telecom operators to manage their fiber optic network and reduce operation and maintenance costs. Target applications of the converter include: FTTx, such as Fiber-to-the-Business, Fiber-to-the-Building, Fiber-to-the-MDU and Fiber-to-the-Home.

- Remote Management - Select stand-alone converters can be managed through SNMP when used in conjunction with a chassis based converter.
- Local and Remote Loopback - This feature puts a converter in a special mode that enables the device to loop back the signal from the RX port to the TX port on either media for testing and troubleshooting purposes.
- Auto-Negotiation for 10/100BASE-TX - Allows devices to perform automatic configuration to achieve the best possible mode of operations over a link.
- AutoCross™ - Automatically detects and configures the twisted pair port on the converter to the correct MDI or MDI-X configuration.
- Link Pass Through for Ethernet - 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.
- 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.
