Instructions before use
2.1 Cleaning
• We recommend manipulating the modulator with rubber gloves (or equivalent) and clean it
with alcohol-soaked optical paper (or equivalent).
• Check optical connectors cleanliness: any dust could damage the connectors or degrade the
optical parameters. Use specific wipes for cleaning optical connector, we recommend using
Whatman ® lens cleaning tissue, Grade 105, wetted with IPA.
• Clean RF connector with dry air before mating and use a torque wrench for tightening.
2.1 Optical interfaces
• Never pinch the fiber pigtail or apply instantaneous traction on it which could generate micro-
cracks in the fibre silica.
• Never bend or coil the fibre jacket under a radius of 30 mm.
Fig. 15
• Pay attention to fiber bends, particularly with the 2000 nm series where any small radius bend
could induce output optical power degradations.
