ETX-21 Fast Ethernet Layer 1 Media Converter

ETX-21 is a media converter that provides transparent conversion of optical and electrical signals for the Fast Ethernet service. The ETX-21  media converter is used to extend the operation distance between two copper Fast Ethernet devices via fiber optic infrastructure transparently and with no performance degradation. The ETX-21 media converter card can be installed in the following enclosures:

LRS-20, 16-slot 3U-high modular rack, accommodating up to 16 hot-swappable converter cards. The LRS-20 rack is intended for central site installation.

LRS-1, 1U high standalone unit, accommodating one converter card. LRS-1 is intended for installation at remote sites, or if only a single converter is required.

The following ETX-21 media converter cards are available (see Table 1 for full details):

ETX-21/UTP/FE-M media converter, converting between UTP and multimode fiber optic cables, 1310 nm

ETX-21/UTP/FE-1 media converter, converting between UTP and single mode fiber optic cables, 1310 nm

ETX-21/UTP/FE-2 , converting between UTP and single mode fiber optic cables, short haul, 1310 nm

ETX-21/UTP/FE-3, converting between UTP and single mode fiber optic cables, long haul, 1550 nm.

The UTP port of the ETX-21 cards supports user-configurable MDI/MDIX function, correcting connection polarity errors. This allows using straight or crossed cables for the LAN connection.

The user-configurable fault propagation mechanism automatically shuts down the UTP port if a failure is detected on the fiber optic port. The UTP link is re-established when the fiber optic connection is restored.

The autonegotiation function automatically matches the UTP port duplex mode and data rate to the user equipment requirements.

LEDs indicate the fiber optic link status, data transmission and duplex modes statuses of the UTP port.
