| Tempo 262A 1310nm and 1550nm Dual Wavelength Laser Source Description: |
Tempo 262A 1310nm and 1550nm Dual Wavelength Laser Source is particularly useful for testing and maintaining telecommunications systems and other long wavelength singlemode fiber optic networks. The single output interface allows the
user to perform fiber optic measurements at the 1310nm or 1550nm transmission windows by pressing a button, eliminating the need to disconnect and reconnect cables when changing wavelengths.
Insertion Loss and Link Loss Testing:
Paired with a TEMPO 555B or 558B optical power meter, the 262A serves as an ideal general purpose dual laser source for measuring the
insertion loss of single-mode fiber optic cables and connectors. With output at 1310nm and 1550nm, the 262A can also be used with an optical power meter for dual wavelength link loss testing of installed cable plants.
Tempo 262A dual laser source is fitted with a precision Universal Connector Interface (UCI), which ensures maximum accuracy and repeatability
when performing critical measurements on fiber optic systems. A comprehensive range of UCI adapters is available for all industry standard fiber optic connectors.
