21 rohs-compliant 4.25 gbps 850 nm transceivers 3.2 package and handling instructions process plug the PLRXPL-VE-SG4-62-x is supplied with a dust cover. this plug protects the transceiver?s optics during standard manufacturing processes by preventing con- tamination from air borne particles. note: it is recommended that the dust cover remain in the transceiver whenever an optical ? ber connector is not inserted. recommended cleaning and de-greasing chemicals jdsu recommends the use of methyl, isopropyl and isobutyl alcohols for cleaning. do not use halogenated hydrocarbons (e.g. trichloroethane, ketones such as ac- etone, chloroform, ethyl acetate, mek, methylene chloride, methylene dichloride, phenol, n-methylpyrolldone). flammability the PLRXPL-VE-SG4-62-x housing is made of cast zinc and sheet metal. 3.3 esd discharge (esd) handling normal esd precautions are required during the handling of this module. this transceiver is shipped in esd protective packaging. it should be removed from the packaging and handled only in an esd protected environment utilizing standard grounded benches, ? oor mats, and wrist straps. test and operation in most applications, the optical connector will protrude through the system chas- sis and be subjected to the same esd environment as the system. once properly installed in the system, this transceiver should meet and exceed common esd testing practices and ful? ll system esd requirements. typical of optical transceivers, this module?s receiver contains a highly sensitive optical detector and ampli? er which may become temporarily saturated during an esd strike. this could result in a short burst of bit errors. such an event might require that the application re-acquire synchronization at the higher layers (e.g. serializer/deserializer chip). 3.4 eye safety the PLRXPL-VE-SG4-62-x is an international class 1 laser product per iec 825, and per cdrh, 21 cfr 1040 laser safety requirements. the plrxpl-ve-sg4- 62-x is an eye safe device when operated within the limits of this speci? cation. operating this product in a manner inco nsistent with intended usage and speci? - cation may result in hazardous radiation exposure.
