Bel FNF-LP11H Front load pluggable optical transceiver Datasheet

FNF-LP11x
Front Load Pluggable Optical Transceiver
The FNF-LP11 multimode glass optical fiber transceivers provide low
profile, cost effective solutions for Fast Ethernet multimode (up to 2.0
km) optical fiber data links with a duplex LC connector interface. These
transceivers are fully compliant with the IEEE 802.3u Fast Ethernet
standard but can be used for any other data communications purpose
within their operating parameters.
This transceiver consist of transmitter and receiver functions combined
in a Low Profile module. The optical transmitter is a high output 1310
nm LED. 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.
The optical receivers consist of PIN and Preamplifier assemblies and
CMOS limiting post-amplifier integrated circuits. Outputs from the
receivers consist of differential LVPECL data signals on the Receive
(RX+ and RX-) pins and a single ended LVPECL Loss of Signal function
on the Loss of Signal (LOS) pin. The RX data is squelched (JAM) upon
LOS Assert to prevent garbage data output when no optical signal is
present

ABSOLUTE MAXIMUM RATINGS
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.
