Electromagnetic Interference (EMI)

Many equipment designs using these high-data-rate

modules will be required to meet the requirements of

the FCC in the United States, CENELEC in Europe and

VCCI in Japan. These modules, with their shielded design,

perform to the levels detailed in the Regulatory Compli-

ance Table. The performance detailed in the Regulatory

Compliance Table is intended to assist the equipment

designer in the management of the overall equipment

EMI performance. However, system margins are

dependent on the customer board and chassis design.

Immunity

Equipment using these modules will be subject to radio

frequency electromagnetic fields in some environ-

ments. These modules have good immunity due to their

shielded designs. See the Regulatory Compliance Table

for further detail.

Eye Safety

These 850 nm VCSEL-based modules provide eye safety

by design. The HFBR-779BWZ has been registered with

CDRH and certied by TUV as a Class 1M device under

Amendment 2 of IEC 60825-1. See the Regulatory Com-

pliance Table for further detail. If Class 1M exposure is

possible, a safety-warning label should be placed on the

product stating the following:

LASER RADIATION

DO NOT VIEW DIRECTLY WITH OPTICAL INSTRUMENTS

CLASS 1M LASER PRODUCT

Connector Cleaning

The optical connector used is the MTP® (MPO). The

optical ports have recessed optics that are visible through

the nose of the ports. The provided port plug should be

installed any time a ber cable is not connected. The port

plug ensures the optics remain clean and no cleaning

should be necessary. In the event the optics become

contaminated, forced nitrogen or clean dry air at less

than 20 psi is the recommended cleaning agent. The

optical port features, including guide pins, preclude use

of any solid instrument. Liquids are not advised due to

potential damage.

Process Plug

Each parallel optics module is supplied with an inserted

process plug for protection of the optical ports within the

MTP® (MTO) connector receptacle.

Handling Precautions

The HFBR-779BWZ and HFBR-789BZ can be damaged by

current surges and over-voltage conditions. Power supply

transient precautions should be taken.

Normal handling precautions for electrostatic sensitive

devices should be taken (see ESD section).

The HFBR-779BWZ is a Class 1M laser product. DO NOT

VIEW RADIATION DIRECTLY WITH OPTICAL INSTRU-

MENTS.

Notes:

1. Absolute Maximum Ratings are those values beyond which damage to the device may occur. See Reliability Data Sheet for specic reliability

performance.

2. Between Absolute Maximum Ratings and the Recommended Operating Conditions functional performance is not intended, device reliability

is not implied, and damage to the device may occur over an extended period of time.

3. This is the maximum voltage that can be applied across the Transmitter Dierential Data Inputs without damaging the input circuit.

4. Case Temperature is measured as indicated in Figure 3.

Recommended Operating Conditions

[1]

Notes:

1. Recommended Operating Conditions are those values outside of which functional performance is not intended, device reliability is not implied,

and damage to the device may occur over an extended period of time. See Reliability Data Sheet for specic reliability performance.

2. Case Temperature is measured as indicated in Figure 3. A 55°C, 1 m/s, parallel to the printed circuit board, air ow at the module or equivalent

cooling is required. See Figure 4.

3. The receiver has a lower cut o frequency near 100 kHz.

4. Data inputs are CML compatible. Coupling capacitors are required to block DC. DV

Notes:

1. Dierential impedance is measured between D

and D

over the range 4 MHz to 2 GHz.

2. When the control signal Transmitter Enable, Tx_EN, is used to disable the transmitter, Tx_EN must be taken to a logic low-state level (VIL) for one

millisecond or longer. Similarly, if the control signal Transmitter Disable, Tx_DIS, is used, then Tx_DIS must be taken to a logic high- state level

(VIH) for one millisecond or longer.
