The AFBR-5601Z has been developed with 850 nm short
wavelength VCSEL technology while the AFCT-5611Z is
based on 1300 nm long wavelength Fabry Perot laser
technology.
The AFBR-5601Z complies with Annex G of the GBIC
specication Revision 5.4. In the 1000 BASE-SX environ-
ment the AFBR-5601Z achieves 220 m transmission
distance with 62.5 µm and 500 m with 50 µm multimode
ber respectively.
The AFCT-5611Z complies with Annex F of the GBIC
specication Revision 5.4 and reaches 10 km with 9/125
µm single mode ber. Both the AFBR-5601Z and the
AFCT-5611Z are Class 1 Eye Safe laser devices.
Serial Identication
The AFBR-56xxZ and AFCT-5611Z family complies with
Annex D (Module Denition 4) of the GBIC specica-
tion Revision 5.4, which denes the Serial Identication
Protocol.
Denition 4 species a serial denition protocol. For this
denition, upon power up, MOD_DEF(1:2) (Pins 5 and
6 on the 20-pin connector) appear as NC. Pin 4 is TTL
ground. When the host system detects this condition, it
activates the public domain serial protocol. The protocol
uses the 2-wire serial CMOS E
2
PROM protocol of the AT-
MEL AT24C01A or similar.
The data transfer protocol and the details of the manda-
tory and vendor specic data structures are dened in
Annex D of the GBIC specication Revision 5.4.
Regulatory Compliance
See the Regulatory Compliance Table for the targeted
typical and measured performance for these transceiv-
ers.
The overall equipment design will determine the level it
is able to be certied to. These transceiver performance
targets are oered as a gure of merit to assist the de-
signer in considering their use in equipment designs.
Note: AFBR-5601Z is non-compliant for Tx fault timing.
Electrostatic Discharge (ESD)
There are two design cases in which immunity to ESD
damage is important.
The rst case is during handling of the transceiver prior
to inserting it into the host system. It is important to
use normal ESD handling precautions for ESD sensitive
devices. These precautions include using grounded wrist
straps, work benches, and oor mats in ESD controlled
areas.
The second case to consider is static discharges during
insertion of the GBIC into the host system. There are two
guide tabs integrated into the 20-pin connector on the
GBIC. These guide tabs are connected to circuit ground.
When the GBIC is inserted into the host system, these
tabs will engage before any of the connector pins. The
mating connector in the host system must have its tabs
connected to circuit ground. This discharges any stray
static charges and establishes a reference for the power
supplies that are sequenced later.
Electromagnetic Interference (EMI)
Most equipment designs utilizing these high-speed trans-
ceivers from Avago Technologies will be required to meet
the requirements of FCC in the United States, CENELEC
EN55022 (CISPR 22) in Europe and VCCI in Japan.
Immunity
Equipment utilizing these transceivers will be subject to
radio-frequency electromagnetic elds in some environ-
ments. These transceivers have good immunity to such
elds due to their shielded design.
Eye Safety
Laser-based GBIC transceivers provide Class 1 (IEC 60825-
1) and Class I (US 21 CFR[J]) laser eye safety by design.
Avago Technologies has tested the current transceiver
design for compliance with the requirements listed below
under normal operating conditions and for compliance
under single fault conditions.
