In the normal handling and operation of optical transceivers, ESD is of concern in two circumstances. The first case is during handling of the transceiver prior to insertion into an SFP+ compliant cage. To protect the device, it’s important to use normal ESD handling pre-cautions. These include use of grounded wrist straps, work-benches and floor wherever a transceiver is handled. The second case to consider is static discharges to the exterior of the host equipment chassis after installation. If the optical interface is exposed to the exterior of host equipment cabinet, the transceiver may be subject to system level ESD requirements. Electromagnetic Interference (EMI) Equipment incorporating gigabit transceivers is typically subject to regulation by the FCC in the United States, CENELEC EN55022 (CISPR 22) in Europe and VCCI in Japan. The RTXM228 compliance to these standards is detailed in Table 2. The metal housing and shielded design of the RTXM228 minimizes the EMI challenge facing the equipment designer. EMI Immunity (Susceptibility) Due to its shielded design, the EMI immunity of the RTXM228 exceeds typical industry standards. Table 2: Regulatory compliance Feature Test Method Performance Electrostatic Discharge (ESD) to the MIL-STD-883C Method 3015.4 Electrical Pins Class 1 (> 1500 Volts) Typically, no damage occurs with 15 Electrostatic Discharge (ESD) to the Duplex LC Receptacle Variation of IEC 61000-4-2 kV when the duplex LC connector receptacle is contacted by a Human Body Model probe.
