Overview Agilent's HFBR-5911L/AL optical transceiver supports high-speed serial links over multimode optical fiber at signaling rates of up to 1.25 Gb/ s. Compliant with the Small Form Factor (SFF) Multi Source Agreement (MSA) for 2 x 5 pin LC Duplex transceivers and IEEE 802.3 specification for Gigabit Ethernet (GbE) links (1000BASE-SX), the part is interoperable and interchangeable with other conformant devices. Supported Gigabit Ethernet link lengths are described in Table 1, but the transceiver can also be used for other high-speed serial applications, such as iSCSI. The SFF package of the HFBR5911L/AL allows designers of Gigabit Ethernet networking equipment to maximize their use of available board space. The footprint of the HFBR-5911L/AL is significantly smaller than those of other GbE transceivers formats - 25% smaller than SFP cage assemblies, 30% smaller than traditional 1 x 9 transceivers and 70% smaller than GBIC rail assemblies. The HFBR-5911L/AL trace keep-out area is less than 10% as large as that required by SFP transceivers. For applications not requiring hot-pluggability, the HFBR-5911L/AL offers a more space-efficient package without the additional cost and complexity imposed by pluggable architecture. Module Diagrams The major functional components of the HFBR-5911L/AL are illustrated in Figure 2 page 9. The external configuration of the transceiver is depicted in Figure 3 page 10 while the host board and front panel layouts defined by the SFF MSA are shown in Figure 4, page 11. 2
Transmitter Section The transmitter section consists of the Transmitter Optical Subassembly (TOSA) and laser driver circuitry. The TOSA, containing an 850 nm VCSEL (Vertical Cavity Surface Emitting Laser) light source, is located at the optical interface and mates with the LC optical connector. The TOSA is driven by a custom IC which uses the incoming differential PECL logic signals to modulate the laser diode drive current. This Tx laser driver circuit regulates the optical output power at a constant level provided that the incoming data pattern is dc balanced (8B10B code for example). Tx_Disable The HFBR-5911L/AL accepts a TTL transmit disable control signal input which shuts down the transmitter. A high signal implements this function while a low signal allows normal transceiver operation. In the event of a fault (e.g., eye safety circuit activated), cycling this control signal resets the module as depicted in Figure 5 page 12. A pull-down resistor enables the laser if the line is not connected on the host board. Host systems should allow a 10 ms interval between successive assertions of this control signal. Eye Safety Circuit The HFBR-5911L/AL provides Class 1 eye safety by design and has been tested for compliance with the requirements listed in Table 11. The eye safety circuit continuously monitors optical output power levels and will disable the transmitter upon detecting an unsafe condition. Such unsafe conditions can be due to inputs from the host board (VCC fluctuation, unbalanced code) or faults within the transceiver.
Receiver Section The receiver section includes the Receiver Optical Subassembly (ROSA) and the amplification/ quantization circuitry. The ROSA, containing a PIN photodiode and custom transimpedance preamplifier, is located at the optical interface and mates with the LC optical connector. The ROSA output is fed to a custom IC that provides post-amplification and quantization. Signal Detect The post-amplification/ quantizer IC also includes transition detection circuitry that monitors the ac level of the incoming optical signal and provides a TTL status signal to the host. An adequate optical input results in a high output while a low Signal Detect output indicates an unusable optical input. The Signal Detect thresholds are set so that a low output indicates a definite optical fault has occurred (e.g., disconnected or broken fiber connection to receiver, failed transmitter, etc.). 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 industrystandard 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).

Notes: 11. The maximum Optical Output Power complies with IEEE 802.3 and is Class 1 laser eye safe. 12. Optical Extinction Ratio is defined as the ratio of the average optical power of the transmitter in the high ("1") state to the low ("0") state. The transmitter is driven with a Gigabit Ethernet 1250 MBd 8b/10b encoded serial data pattern. Optical Extinction Ratio is expressed in decibels (dB) by the relationship 10log(Phigh avg/Plow avg). 13. Optical Rise and Fall Times are 20-80% value. Laser transmitter pulse characteristics are typically specified by an eye diagram - see Figure 6. The characteristics include rise time, fall time, pulse overshoot, pulse undershoot and ringing, all of which are controlled to prevent excessive degradation of receiver sensitivity. These parameters are specified by the referenced Gigabit Ethernet eye diagram using the required filter. The output optical waveform complies with the requirements of the eye mask described in IEEE 802.3 section 38.6.10 and Figure 38-2. 14. CPR is measured in accordance with EIA/TIA-526-14A as referenced in IEEE 802.3 section 38.6.10. 15. Measured at TP2. TP refers to the compliance point specified by IEEE 802.3, section 38.2.1. 16. Tested with a 100 mVP-P sinusoidal signal in the frequency range from 10 Hz to 2 MHz on the VCC supply with the recommended power supply filter (with C8) in place. Typically, a change in sensitivity of less than 1 dB is experienced.
