Description
The NLP20-series small form-factor pluggable (SFP)
transceiver is a line of high-speed, cost-effective
optical transceivers intended for 1G (1.0625 Gb/s)
and 2G (2.125 Gb/s) Fibre Channel applications in
link lengths from less than 300 m to 80 km. These
transceivers feature TriQuint Optoelectronics optics
and are packaged in a narrow-width metal housing
with an LC duplex receptacle. The packaging and
pinout conform to the SFP transceiver multisource
agreement.
The transmitter features ac-coupled differential data
inputs, an LVTTL logic level disable input, and a
transmitter fault indicator output. The receiver
features differential ac-coupled data outputs and a
LVTTL logic level loss-of-signal output.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in
excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.
