Applications
The LxLx-ST11xx multimode optical fiber transceivers
provide low profile, cost effective solutions for rate agile
1x/2x Fiber Channel multimode optical fiber data links with a
duplex LC connector interface. These transceivers are fully
compliant with the ANSI Fiber Channel standards but can be
used for any other data communications purpose within
their operating parameters.

Product Overview
The Emerson Network Power Connectivity Solutions LxLx-
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. The High Power Low Profile optic
transceiver family is based upon the Standard Power LxLx-
ST11x product, with the addition of higher optical output
power options.

Absolute Maximum Ratings

TM
Absolute maximum limits mean that no catastrophic damage will occur if the product is subjected to these ratings for short
periods, provided each limiting parameter is in isolation and all other parameters have values within the performance
specification. It should not be assumed that limiting values of more than one parameter can be applied to the product at the
same time.
