Description The HFBR-56xx/HFCT-56xx family of interface converters meet the Gigabit Interface Converter specification Rev. 5.4, an industry standard. The family provides a uniform form factor for a wide variety of standard connections to transmission media. The converters can be inserted or removed from a host chassis without removing power from the host system. The converters are suitable for interconnections in the Gigabit Ethernet hubs and switches environment. The design of these converters is also practical for other high performance, point-topoint communication requiring gigabit interconnections. Since the converters are hot-pluggable, they allow system configuration changes simply by plugging in a different type of converter.
The mechanical and electrical interfaces of these converters to the host system are identical for all implementations of the converter regardless of external media type. A 20-pin connector is used to connect the converter to the host system. Surge currents are eliminated by using pin sequencing at this connector and a slow start circuit. Two ground tabs at this connector also make contact before any other pins, discharging possible componentdamaging static electricity. In addition, the connector itself performs a two-stage contact sequence. Operational signals and power supply ground make contact in stage 1 while power makes contact in stage 2. The HFBR-5601 has been developed with 850 nm short wavelength VCSEL technology while the HFCT-5611 is based on 1300 nm long wavelength Fabry Perot laser technology.
The HFBR-5601 complies with Annex G of the GBIC specification Revision 5.4. In the 1000 BASE-SX environment the HFBR-5601 achieves 220 m transmission distance with 62.5 m and 500 m with 50 m multimode fiber respectively. The HFCT-5611 complies with Annex F of the GBIC specification Revision 5.4 and reaches 10 km with 9/125 m single mode fiber. Both the HFBR-5601 and the HFCT-5611 are Class 1 Eye Safe laser devices. Serial Identification The HFBR-56xx and HFCT-5611 family complies with Annex D (Module Definition 4) of the GBIC specification Revision 5.4, which defines the Serial Identification Protocol. Definition 4 specifies a serial definition protocol. For this definition, 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 E2PROM protocol of the ATMEL AT24C01A or similar. The data transfer protocol and the details of the mandatory and vendor specific data structures are defined in Annex D of the GBIC specification Revision 5.4.
Regulatory Compliance See the Regulatory Compliance Table for the targeted typical and measured performance for these transceivers. The overall equipment design will determine the level it is able to be certified to. These transceiver performance targets are offered as a figure of merit to assist the designer in considering their use in equipment designs. Electrostatic Discharge (ESD) There are two design cases in which immunity to ESD damage is important. The first 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 floor 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 transceivers from Agilent 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 fields in some environments. These transceivers have good immunity to such fields 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. Agilent has tested the current transceiver design for compliance with the requirements listed below under normal operating conditions and for compliance under single fault conditions. Outline Drawing An outline drawing is shown in Figure 1. More detailed drawings are shown in Gigabit Interface Converter specification Rev. 5.4.
Note: HFBR-5601 is non-compliant for Tx fault timing.

Optical Power Budget and Link Penalties The worst-case Optical Power Budget (OPB) in dB for a fiber optic link is determined by the difference between the minimum transmitter output optical power (dBm avg) and the lowest receiver sensitivity (dBm avg). This OPB provides the necessary optical signal range to establish a working fiber-optic link. The OPB is allocated for the fiber-optic cable length and the corresponding link penalties. For proper link performance, all penalties that affect the link performance must be accounted for within the link optical power budget. The Gigabit/sec Ethernet (GbE) IEEE 802.3z standard identifies, and has modeled, the contributions of these OPB penalties to establish the link length requirements for 62.5/125 m and 50/125 m multimode fiber usage. In addition, single-mode fiber with standard Regulatory Compliance
1300 nm Fabry Perot lasers have been modeled and specified. Refer to IEEE 802.3z standard and its supplemental documents that develop the model, empirical results and final specifications. 10 km Link Support As well as complying with the LX 5 km standard, the HFCT-56xx specification provides additional margin allowing for a 10 km Gigabit Ethernet link on single mode fiber. This is accomplished by limiting the spectral width and center wavelength range of the transmitter while increasing the output optical power and improving sensitivity. All other LX cable plant recommendations should be followed. CAUTION: There are no user serviceable parts nor any maintenance required for the HFBR-56xx and HFCT-56xx product family. All adjustments are made at the
factory before shipment to our customers. Tampering with or modifying the performance of any Agilent GBIC unit will result in voided product warranty. It may also result in improper operation of the circuitry, and possible overstress of the semiconductor components. Device degradation or product failure may result. Connection of either the HFBR-5601 or the HFCT-5611 to a non-approved optical source, operating above the recommended absolute maximum conditions, or operating in a manner inconsistent with unit design and function, may result in hazardous radiation exposure and may be considered an act of modifying or manufacturing a laser product. The person(s) performing such an act is required by law to recertify the laser product under the provisions of US 21 CFR (Subchapter J).

Short Wavelength GBIC: HFBR-5601 Transmitter Section The transmitter section consists of an 850 nm VCSEL in an optical subassembly (OSA), which mates to the fiber cable. The VCSEL OSA is driven by a custom, silicon bipolar IC which converts differential logic signals into an analog Laser Diode drive current. Receiver Section The receiver includes a GaAs PIN photodiode mounted together with a custom, silicon bipolar transimpedance preamplifier IC, in an OSA. The OSA interfaces to a custom silicon bipolar circuit Absolute Maximum Ratings
that provides post-amplification and quantization. The postamplifier includes a Signal Detect circuit that provides TTL compatible logic-low output in response to the detection of a usable input optical signal. Eye Safety Design The laser driver is designed to be Class 1 eye safe (CDRH21 CFR(J), IEC 60825-1) under a single fault condition. To be eye safe, only one of two results can occur in the event of a single fault. The transmitter must either maintain normal eye safe operation or the transmitter should be disabled.
There are three key elements to the safety circuitry: a monitor diode, a window detector circuit, and direct control of the laser bias. The window detection circuit monitors the average optical power using the monitor diode. If a fault occurs such that the dc regulation circuit cannot maintain the preset bias conditions within 20%, the transmitter will automatically be disabled. Once this has occurred, an electrical power reset will allow an attempted turn-on of the transmitter. TX_FAULT can also be cleared by cycling TX_DISABLE high for a time interval >10 s.
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parameter in isolation, all other parameters having values within the recommended operating conditions. It should not be assumed that limiting values of more than one parameter can be applied to the product at the same time. Exposure to the absolute maximum ratings for extended periods can adversely affect device reliability.

Long Wavelength GBIC: HFCT-5611 Transmitter Section The transmitter section consists of a 1300 nm MQW Fabry Perot Laser in an optical subassembly (OSA), which mates to the fiber optic cable. The Laser OSA is driven by a custom, silicon bipolar IC which converts differential PECL logic signals (ECL referenced to a +5 V supply) into an analog drive current to the laser. The laser driver IC incorporates temperature compensation and feedback from the OSA to maintain constant output power and extinction ratio over the operating temperature range. Absolute Maximum Ratings
Receiver Section The receiver includes a PIN photodiode mounted together with a custom, silicon bipolar transimpedance preamplifier IC, in an OSA. The OSA interfaces to a custom silicon bipolar circuit that provides post-amplification and quantization. The postamplifier includes a Signal Detect circuit that provides TTL compatible logic-low output in response to the detection of a usable input optical signal. Eye Safety Design The laser driver is designed to be Class 1 eye safe (CDRH21 CFR(J), IEC 60825-1) under a single fault condition.
There are three key elements to the safety circuitry: a monitor diode, a window detector circuit, and direct control of the laser bias. The window detection circuit monitors the average optical power using the photo diode in the laser OSA. If a fault occurs such that the dc bias circuit cannot maintain the preset conditions within 20%, TX_FAULT (Pin 10) will be asserted (high). Note: Under any single fault, the laser optical output power will remain within Class 1 eye safe limits.
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parameter in isolation, all other parameters having values within the recommended operating conditions. It should not be assumed that limiting values of more than one parameter can be applied to the product at the same time. Exposure to the absolute maximum ratings for extended periods can adversely affect device reliability.
