42 APOLLO Digital Broadcast Production Console Connection InformationCleaningfibreopticcablesandconnectorsThere are multiple ways to clean fibre-optic cables and connectors.Included below are some helpful tips toproperly clean fibre optic cables.• Do not allow the end of the fibre opticcable to make contact with any surfaceincluding fingers.• Do not excessively bend the fibrecable. Bending the cable may causeinternal breaks along the fibre resultingin poor performance or instability.• Optics and optic coatings are easilychipped and/or scratched. Use offinger cots or powder free surgicalgloves while handling fibre optic cables,will help ensure cleanliness.• Only fresh (dry) spectroscopic gradeIsopropyl Alcohol should be used as acleaning solvent.• Ensure that the module power isoff and that other light sources aredisabled.Cleaningprocedure1. Blow the fibre surface with a stream ofClean Dry Air, this will dislodge largerloose particles.2. Place 1-3 drops of spectroscopic gradeIsopropyl Alcohol in the centre of a lenstissue.3. Hold the fibre by the connector orcable, place the wet portion of the lenstissue on the optical surface and slowlydrag it across.4. Examine the surface of the fibre endunder high intensity light using a directmagnifying inspection microscopeor an indirect video inspection tool ifavailable. If streaks or contaminantsstill remain, repeat the process using afresh lens tissue.5. Immediately install a protective coverover the end of the cable to avoid re-contamination or insert the fibre backinto the previously cleaned receptaclefor immediate use.AdditionalnotesDo not tip the can of Clean Dry Air whilstaerosol spraying as liquid may be releasedcontaminating the surface of the fibre.Do not use lens paper dry as dry lenspaper is extremely abrasive.Do not use Acetone as a cleaning solventon the fibre optical surfaces.To ensure the purity of the IsopropylAlcohol, do not insert the lens tissue,swabs, etc into the liquid, instead, drip theliquid on to the material.CleaningopticaltransceiversThe best way to clean a transceiver portis to remove particles using a stream ofClean Dry Air.Included below are some helpful tips toproperly clean fibre optic modules.• Always handle optical SFP modules inan ESD safe manner using the propersafety precautions.• Ensure that the module power is offand handle the modules with care.• Always use Clean Dry Air or anapproved canned compressed airsupply.• Always hold the can of compressed airupright. Tipping may release liquidsinto the air stream.• Do not touch the inner surfaces of themodule including the Optical Sub-Assemblies (OSA), or insert any foreignobjects into the ports.• Use of finger cots or powder freesurgical gloves are not required butmay be used for cleanliness.Cleaningprocedure1. With the clean dry air, blow the innerbarrel of the Transmitter and ReceiverOptical Sub-Assemblies (OSA).This will dislodge loose particles.2. Examine the surface of the OSA lensunder high intensity light using theinspection microscope. If contaminantsstill remain, repeat the process.Following these guidelines shouldprovide a successful installation andensure optimum reliability and systemperformance.For further information or advice pleasefeel free to contact Calrec.
