Tunable lasers are an integral part of optical test systems to measure insertion loss, isolation, polarization dependence, wavelength dependence and reflectivity of optical components.   As experts in tunable laser technology, Santec built the world’s first commercially available external cavity tunable laser back in 1987.  This year they introduce their latest model tunable laser, the TSL-550.  Innovation in tunable laser resonator design in the TSL-550 results in lower optical ASE for extraordinarily high signal-to-noise ratio of over 90dB/0.1nm, while maintaining a high output power of over +10dBm.  The TSL-550 features key advances in testing speed, resolution, accuracy and dynamic range, raising confidence and lowering costs of component verification.  Equipped as standard with fine tuning and coherence control, the TSL-550 is fully programmable, making it a must have tool for precision optical testing.

FibreFab’s QuickFlip™ LC Connector is a new and innovative solution to the polarity reversal problem. The well known duplex LC connector has been re-engineered to provide a simple and easy way to reverse the fibre’s polarity. The connector is made of two parts with a removable front assembly allowing a simple “Remove, Rotate and Reassemble” action to reverse the polarity. The rear of the assembly, containing ferrules, fibre and cable retention, remains intact and the fibres are undisturbed. This is a unique feature of QuickFlip™.
