ETX-41 Gigabit Ethernet Layer 1 Media Converter FEATURES • Provides cost-effective UTP-to-fiber media conversion for Gigabit Ethernet services • Can be installed in the following enclosures: 16-slot modular rack for central site installation (LRS-20) Single-slot standalone unit for remote site installation, or if a single converter is needed (LRS-1) • Operates over multimode and single mode fiber optic cables • Uses 850, 1310 and 1550 nm lasers • Transparent operation without signal degradation • Automatic MDI/MDIX crossover • User-configurable fault propagation • Autonegotiation • LED indicators for the connection status ETX-41 Gigabit Ethernet Layer 1 Media Converter DESCRIPTION • ETX-41 is a media converter that provides transparent conversion of optical and electrical signals for the Gigabit Ethernet service. • The media converter is used to extend the operation distance between two copper Gigabit Ethernet devices via fiber optic infrastructure transparently and with no performance degradation. • The ETX-41 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-41 cards are available (see Table 1 for full details): ETX-41/UTP/GE-M, converting between UTP and multimode fiber optic cables, 850 nm ETX-41/UTP/GE-1, converting between UTP and single mode fiber optic cables, 1310 nm ETX-41/UTP/GE-2, converting between UTP and single mode fiber optic cables, short haul, 1550 nm ETX-41/UTP/GE-3, converting between UTP and single mode fiber optic cables, long haul, 1550 nm. • 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. • The UTP port of the ETX-41 cards supports automatic MDI/MDIX function, correcting connection polarity errors. This allows using straight or crossed cables for the LAN connection. APPLICATIONS Figure 1.
