Regulatory Compliance

The AFBR-709DMZ complies with all applicable laws

and regulations as detailed in Table 1. Certification level

is dependent on the overall configuration of the host

equipment. The transceiver performance is offered as a

figure of merit to assist the designer.

Electrostatic Discharge (ESD)

The AFBR-709DMZ is compatible with ESD levels found

in typical manufacturing and operating environments

as described in Table 1. 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 10 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 AFBR-709DMZ enables equipment compli-

ance to these standards detailed in Table 1. The metal

housing and shielded design of the AFBR-709DMZ mini-

mizes the EMI challenge facing the equipment designer.

For superior EMI performance it is recommended that

equipment designs utilize SFP+ cages per SFF 8432.

RF Immunity (Susceptibility)

Due to its proprietary bulk optics TOSA and ROSA de-

sign, the EMI immunity of the AFBR-709DMZ exceeds

typical industry standards.

Eye Safety

The AFBR-709DMZ provides Class 1 (single fault

tolerant) eye safety by design and has been tested for

compliance with the requirements listed in Table 1. The

eye safety circuit continuously monitors the optical out-

put power level and will disable the transmitter upon

detecting a condition beyond the scope of Class 1 cer-

tification Such conditions can be due to inputs from the

host board (Vcc fluctuation, unbalanced code) or a fault

within the transceiver. US CDRH and EU TUV certificates

are listed in table 1.

Flammability

The AFBR-709DMZ optical transceiver is made of metal

and high strength, heat resistant, chemical resistant and

UL 94V-0 flame retardant plastic.
