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
