AFCT-5943XXZ

Single Mode SFF Transceivers for SONET OC-48/SDH STM-16 Multirate Operation

Avago Technologies 

Recommended Solder and Wash Process

The AFCT-5943xxZ are compatible with industry-stan-

dard wave solder processes.

Process plug

This transceiver is supplied with a process plug for

protection of the optical port within the LC connector

receptacle. This process plug prevents contamination

during wave solder and aqueous rinse as well as during

handling, shipping and storage. It is made of a high-

temperature, molded sealing material that can with-

stand +85°C and a rinse pressure of 110 lbs per square

inch.

Regulatory Compliance

The Regulatory Compliance for transceiver perform-

ance is shown in Table 1. The overall equipment design

will determine the certification level. The transceiver

performance is offered as a figure of merit to assist the

designer in considering their use in equipment designs.

Electrostatic Discharge (ESD)

The device has been tested to comply with MIL-STD-

883E (Method 3015). It is important to use normal ESD

handling precautions for ESD sensitive devices. These

pre­cautions include using grounded wrist straps, work

benches, and floor mats in ESD controlled areas.

Recommended Solder fluxes

Solder fluxes used with the AFCT-5943xxZ should be

water-soluble, organic fluxes. Recommended solder

fluxes include Lonco 3355-11 from London Chemical

West, Inc. of Burbank, CA, and 100 Flux from Alpha-Met-

als of Jersey City, NJ.

Electromagnetic Interference (EMI)

Most equipment designs utilizing these high-speed

transceivers from Avago Technologies will be required

to meet FCC regulations in the United States, CENELEC

EN55022 (CISPR 22) in Europe and VCCI in Japan. Refer

to EMI section (page 9) for more details.

Recommended Cleaning/Degreasing Chemicals

Alcohols: methyl, isopropyl, isobutyl.

Aliphatics: hexane, heptane

Other: naphtha.

Do not use partially halogenated hydrocar-

bons such as 1,1.1 trichloroethane, ketones such

as MEK, acetone, chloroform, ethyl acetate, meth-

ylene dichloride, phenol, methylene chloride, or

N-methylpyrolldone. Also, Avago Technologies does not

recommend the use of cleaners that use halogenated

hydrocarbons because of their potential environmental

harm.

LC SFF Cleaning Recommendations

In the event of contamination of the optical ports, the

recommended cleaning process is the use of forced

nitrogen. If contamination is thought to have remained,

the optical ports can be cleaned using a NTT interna-

tional Cletop stick type (diam. 1.25mm) and HFE7100

cleaning fluid.

Immunity

Transceivers will be subject to radio-frequency electro-

magnetic fields following the IEC 61000-4-3 test method.

Eye Safety

These laser-based transceivers are classified as AEL

Class I (U.S. 21 CFR(J) and AEL Class 1 per EN 60825-

1 (+A11). They are eye safe when used within the

data sheet limits per CDRH. They are also eye safe

under normal operating conditions and under all

reasonably foreseeable single fault conditions per

EN60825-1. Avago Technologies has tested the trans-

ceiver design for compliance with the requirements

listed below under normal operating conditions and

under single fault conditions where applicable. TUV

Rheinland has granted certification to these trans-

ceivers for laser eye safety and use in EN 60950 and

EN 60825-2 applications. Their performance enables the

transceivers to be used without concern for eye safety

up to 3.6 V transmitter VCC.
