The HFBR-53A5VEMZ/FMZ transceiver housing is made of high strength, heat resistant, chemically resistant, The first case is during handling of the transceiver prior and UL 94V-0 flame retardant plastic. to mounting it on the circuit board. It is important to use normal ESD handling precautions for ESD sensitive Recommended Solder and Wash Process devices. These precautions include using g rounded The HFBR-53A5VEMZ/FMZ is compatible with industry- wrist straps, work benches, and floor mats in ESD standard wave or hand solder processes. controlled areas.

This transceiver is supplied with a process plug (HFBR-5000) for protection of the optical ports within The second case to consider is static discharges to the duplex SC connector receptacle. This process the exterior of the equipment chassis containing the plug prevents contamination during wave solder and transceiver parts.

The transceiver performance is more robust than typical industry equipment requirements of today. Recommended Solder Fluxes Solder fluxes used with the HFBR-53A5VEMZ/FMZ Electromagnetic Interference (EMI) should be water-soluble, organic fluxes. Recom mended Most equipment designs utilizing these high-speed solder fluxes include Lonco 3355-11 from London transceivers from Avago will be required to meet the Chemical West, Inc. of Burbank, CA, and 100 Flux from requirements of FCC in the United States, CENELEC Alpha-Metals of Jersey City, NJ.
