Electrical Interfaces
The HFBR-5911L/AL interfaces with the host circuit
board through the ten I/O pins identified by function
in Table 4. These pins are sized for use in boards
between 0.062 in. and 0.100 in. thick. The board layout
for this interface is depicted in Figure 4.
The HFBR-5911L/AL transmit and receive interfaces
require PECL differential signal lines on the host board.
To simplify board requirements, transmitter bias
resistors and ac coupling capacitors are incorporated
into the transceiver module and so are not required on
the host board.
The Tx_Disable and Signal Detect lines require TTL lines
on the host board if they are to be utilized. The
transceiver will operate normally if these lines are not
connected on the host board.
Figure 2 depicts a recommended interface circuit to
link the HFBR-5911L/AL to the supporting physical layer
ICs.
Timing for the MSA compliant control signals
implemented in this transceiver are listed in Table 9
and diagramed in Figure 5.
PCB Assembly Process Compatibility
The HFBR-5911L/AL is compatible with industry-
standard wave solder and aqueous wash processes as
detailed in Table 10. The transceiver is shipped with a
process plug to keep out impinging liquids, but is not
intended to be immersed. After assembly, the process
plug should be kept in place as a dust plug when the
transceiver is not in use.
Regulatory Compliance
The HFBR-5911L/AL complies with all applicable laws
and regulations as detailed in Table 11. Certification
level is dependent of 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 HFBR-5911L/AL is compatible with ESD levels found
in typical manufacturing and operating environments
as described in Table 11. 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 soldering onto the host board. To protect the device,
it’s important to use normal ESD handling precautions.
These include using grounded wrist straps,
workbenches and floor mats wherever the transceiver
is handled.

The second case to consider is static discharges to the
exterior of the host equipment chassis after assembly.
If the optical interface is exposed to the exterior of the
host equipment cabinet, the transceiver may be subject
to system-level ESD requirements.
EMI Immunity
Due to its shielded design, the EMI immunity of the
HFBR-5911L/AL exceeds typical industry standards.
Electromagnetic Interference (EMI)
Equipment incorporating Gigabit transceivers is
typically subject to regulation by the FCC in the United
States, TUV in the European Union and VCCI in Japan.
The HFBR-5911L/AL’s compliance to these standards is
detailed in Table 11.
The metal housing and shielded design of the HFBR-
5911L/AL minimize the EMI challenge facing the
equipment designer.
Flammability
The HFBR-5911L/AL optical transceiver is made of metal
and high strength, heat resistant, chemical resistant and
UL 94V-0 flame retardant plastic.
Caution
There are no user serviceable parts nor any
maintenance required for the HFBR-5911L/AL. All
adjustments are made at the factory before shipment.
Tampering with, modifying, misusing or improperly
handling the HFBR-5911L/AL will void the product
warranty. It may also result in improper operation and
possibly overstress the laser source. Performance
degradation or device failure may result. Connection
of the HFBR-5911L/AL to a light source not compliant
to the Gigabit Ethernet specification (IEEE 802.3),
operating above the recommended absolute maximum
operating conditions or in a manner inconsistent with
it’s design and function may result in exposure to
hazardous radiation and may constitute an act of
modifying or manufacturing a laser product. Person’s
performing such an act are required by law to recertify
and re-identify the laser product under the provisions
of U.S. 21 CFR (Subchapter J).
