6 eye safety the afct-571 x z transceivers provide class 1 eye safety by design. avago technologies has tested the transceiver design for regulatory compliance, under normal operating conditions and under a single fault condition. see table 1. flammability the afct-571 x z family of sfps is compliant to ul 94v-0. customer manufacturing processes this module is pluggable and is not designed for aqueous wash, ir refl ow, or wave soldering processes. caution the afct-571 x z contains no user-serviceable parts. tampering with or modifying the performance of the afct-571 x z will result in voided product warranty. it may also result in improper operation of the transceiver circuitry, and possible over-stress of the laser source. device degradation or product failure may result. connection of the afct-571 x z to a non-approved optical source, operating above the recommended absolute maximum conditions may be considered an act of modifying or manufacturing a laser product. the person(s) performing such an act is required by law to re-certify and re-identify the laser product under the provisions of u.s. 21 cf. electrostatic discharge (esd) there are two conditions in which immunity to esd damage is important: the fi rst condition is static discharge to the transceiver during handling such as when the transceiver is inserted into the transceiver port. to protect the transceiver, it is important to use normal esd handling precau- tions including the use of grounded wrist straps, work benches, and fl oor mats in esd controlled areas. the esd sensitivity of the afct-571 x z is compatible with typical industry production environments. the second condition is static discharge to the exterior of the host equipment chassis after installation. to the extent that the duplex lc optical interface is exposed to the outside of the host equipment chassis, it may be subject to system-level esd requirements. the esd per- formance of the afct-571 x z exceeds typical industry standards. table 1 documents esd immunity to both of these conditions. electromagnetic interference (emi) most equipment designs using the afct-571 x z sfps are subject to the requirements of the fcc in the united states, cenelec en55022 (cispr 22) in europe and vcci in japan. the metal housing and shielded design of the transceiver minimize emi and provide excellent emi performance. emi immunity the afct-571 x z transceivers have a shielded design to provide excellent immunity to radio frequency electromagnetic fi elds which may be present in some operating environments.
