Product description
Back to top |
S-Light SLT-250-IQ-Pyz optoelectronic transmitters are single channel
transmitters optimized for short distance high data rate optical communications.
The SLT-250-IQ-Pyz
is optimized for severe environments applications and complies with
AEEC / ARINC 804 transmitter specifications.
SLT-250-IQ-Pyz
modules integrate state-of-the art 850-nm AlGaAs VCSEL and low power
consumption CMOS electronics. SLT-250-IQ-Pyz optical interface consists
of either a 50/125 or a 62.5/125 µm multimode optical cable
pigtail terminated by the end-user specified optical terminus or connector.
SLT-250-IQ-Pyz electrical interface consist of a QFN package.
A versatile input stage allows 100 W differential or 50 W to ground
termination resistors to comply with CML or LVDS signalling levels.

Principal Parameters
Back to top |
|
Notes:
1.
Power consumption when operating at full speed over the temperature
range. Maximum power consumption
occurs at 90°C.
2.
The module operates with decreased performances above 90°C. |
|
|
Notes:
1.
SLT-250-IQ-Pyz transmitters are not Class I laser products according
to IEC 60825-1 standard.
2.
The output optical power is regulated over the temperature range.
The optical power can
be adjusted by the user through a 2-Wire serial interface.
3.
Over specified operating temperature range
4.
The module is compliant with ARINC 804 long term temperature tests. |
