The AFCT-570xZ transceivers provide Class 1 eye safety by design. Avago Technologies has tested the trans- ceiver design for regulatory compliance, under normal operating conditions and under a single fault condition. See Table 1. Flammability The AFCT-570xZ 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-570 xZ contains no user-serviceable parts. Tampering with or modifying the performance of the AFCT-570xZ 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. Con- nection of the AFCT-570 xZ to a non-approved optical source, operating above the recommended absolute maximum conditions may be considered an act of mod- ifying 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 precautions in- cluding the use of grounded wrist straps, work benches, and fl oor mats in ESD controlled areas. The ESD sensitiv- ity of the AFCT-570xZ 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-570 xZ exceeds typical industry standards. Table 1 documents ESD immunity to both of these conditions. Electromagnetic Interference (EMI) Most equipment designs using the AFCT-570xZ 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-570xZ transceivers have a shielded design to provide excellent immunity to radio frequency electro- magnetic fi elds which may be present in some operat- ing environments.
