Lx10G-ST11xx Low Profile
Optical Transceiver
10G Ethernet (10.3125Gbps), 3.3V, 850nm VCSEL,
Multimode, Up to 50 Meters
Applications
The Lx10G-ST11xx multimode optical fiber transceivers provide low profile, cost
effective solutions for rate agile 10G Ethernet multimode optical fiber data links, with
a duplex LC connector interface. These transceivers are intended to work with 10G
Ethernet applications but can be used for any other data communications purpose
within their operating parameters.
Product Overview
The Cinch Connectivity Solutions Lx10G-ST11xx fiber optic transceivers consist of
transmitter and receiver functions combined in a Low Profile RJ Format module. The
optical transmitter is a high output 850nm VCSEL. The transmitter input lines are
driven with differential LVPECL Signals applied to the Transmit (TX+ and TX-) pins.
These signals are internally converted to a suitable modulation current by a CMOS
integrated circuit. A Transmit Disable (TDIS) function is provided to enable control
of the VCSEL optical output. The optical receivers consist of PIN and Preamplifier
assemblies and CMOS limiting post-amplifier integrated circuits. Outputs from the
receivers consist of differential CML data signals on the Receive (RX+ and RX-)pins
and a single ended LVTTL signal detect function on the Signal Detect (SD) pin. The
RX data is squelched (JAM) upon Signal Detect deassert to prevent garbage data
output when no optical signal is present.
