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.
