## **Data Sheet** 

## **Description** 

The Avago Technologies’ AFBR-2CARxxZ Active Optical Cable (AOC) is part of a family of SFP+ products to serve 10Gb Ethernet (10GbE) applications.  The letters “xx” of the part number AFBR-2CARxxZ denoted the cable length in meters.  The AFBR-2CARxxZ AOC enables 10GbE equipment designs with very high port density based on the new electrical and mechanical specification enhancements to the well known SFP specifications developed by the SFF Committee. The specifications are referred to as “SFP+” to represent the enhancements over previous SFP specifications. The SFP+ AOC have a cable length up to 20m.  These AOCs can be used as an alternative solution to SFP+ passive and active copper cables, while providing improved signal integrity, longer distances, superior electromagnetic immunity and better bit error rate performance.

## **Installation** 

The AFBR-2CARxxZ Active Optical Cable package is compliant with the SFF-8432 Improved Pluggable Formfactor housing specification for the SFP+.  It can be installed in any INF-8074 or SFF-8431/2 compliant Small Form Pluggable (SFP) port regardless of host equipment operating status The AFBR-2CARxxZ is hot-pluggable, allowing both active cable ends to be installed while the host system is operating and on-line. Upon insertion, the housing makes initial contact with the host board SFP cage, mitigating potential damage due to Electro-Static Discharge (ESD). 

## **Digital Interface and Serial Identification** 

The two-wire interface protocol and signaling detail are based on SFF-8431. Conventional EEPROM memory, bytes 0-255 at memory address 0xA0, is organized in compliance with SFF-8431. The EEPROM contents of AFBR-2CARxxZ are such that it can directly replace the Active Copper Cable. 

## **Transmitter Section** 

The transmitter section includes an 850 nm VCSEL (Vertical Cavity Surface Emitting Laser) light source designed and manufactured by Avago Technologies. The VCSEL is driven by an IC which uses the incoming differential high speed logic signal to modulate the laser diode driver current. This Tx laser driver circuit regulates the optical power at a constant level provided the incoming data pattern is DC balanced.  DC blocking capacitors are located inside the AOC package and are not required on the system board. 

## **Transmit Disable (TX_DISABLE)** 

Each end of the AFBR-2CARxxZ AOC has a TX_DISABLE hardware pin, which accepts an input LVTTL compatible control signal that shuts down the transmitter optical output. A logic high signal implements the transmitter disable function, while a low signal allows normal transmitter operation. An internal pull up resistor disables the transmitter until the host pulls the input low. 

## **Receiver Section** 

The receiver section includes a PIN photodiode and custom amplification and quantization IC. DC blocking capacitors are located inside the AOC package and are not required on the system board. 

## **Receiver Loss of Signal (Rx_LOS)** 

The Rx portion of the IC includes detection circuitry which monitors the average input Rx optical power and provides a LVTTL/CMOS compatible status signal to the host via the Rx_LOS pin. A logic high status on this Rx_ LOS output pin indicates a loss of signal, indicating a link failure such as a broken fiber, or the far-end cable-end is not plugged in, or the far-end Tx has failed or has been disabled. 

## **Functional Data I/O** 

The AFBR-2CARxxZ interfaces with the host circuit board through the twenty contact SFP+ electrical connector. See Table 2 for contact descriptions.  The device edge connector is shown in Figure 2. 

The AFBR-2CARxxZ high speed transmit and receive interfaces require SFF-8431 compliant signal lines on the host board. The TX_DISABLE and RX_LOS signals require LVTTL signals on the host board (per SFF-8431) if used. If an application does not take advantage of these functions, care must be taken to ground TX_DISABLE to enable normal operation.

## **Application Support** 

An Evaluation Kit and Reference Designs are available to assist in evaluation of the AFBR-2CARxxZ. Please contact your local Field Sales representative for availability and ordering details. 

## **Caution** 

There are no user serviceable parts nor maintenance requirements for the AFBR-2CARxxZ. All mechanical adjustments are made at the factory prior to shipment. Tampering with, modifying, misusing or improperly handling the AFBR-2CARxxZ will void the product warranty. It may also result in improper operation and possibly overstress the device. Performance degrada tion or device failure may result. Operating above maximum operating conditions or in a manner inconsistent with it’s design and function may result in exposure to hazardous light radiation and may constitute an act of modifying or manufacturing a laser product. Persons 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) and TUV. 

## **Customer Manufacturing Processes** 

This AOC is pluggable and is not designed for aqueous wash, IR reflow, or wave soldering processes. 

## **Ordering Information** 

Please contact your local field sales engineer or one of Avago Technologies franchised distributors for ordering information. For technical information, please visit Avago Technologies’ WEB page at www.avagotech.com.  For information related to SFF Committee documentation visit www.sffcommittee.org. 

## **Regulatory Compliance** 

The AFBR-2CARxxZ complies with all applicable laws and regulations as detailed in Table 1. Certification level is dependent on the overall configuration of the host equipment. The AOC performance is offered as a figure of merit to assist the designer. 

## **Electrostatic Discharge (ESD)** 

The AFBR-2CARxxZ is compatible with ESD levels found in typical manufacturing and operating environments as described in Table 1. In the normal handling and operation of optical cables, ESD is of concern in two circumstances. 

The first case is during handling of the AOC prior to insertion into an SFP+ compliant cage. To protect the device, it’s important to use normal ESD handling pre-cautions. These include use of grounded wrist straps, work-benches and floor wherever a optical cable is handled. 

The second case to consider is static discharges to the exterior of the host equipment chassis after installation. If the optical interface is exposed to the exterior of host equipment cabinet, the optical cable may be subject to system level ESD requirements. 

## **Electromagnetic Interference (EMI)** 

Equipment incorporating 10 gigabit transceivers or active optical cables is typically subject to regulation by the FCC in the United States, CENELEC EN55022 (CISPR 22) in Europe and VCCI in Japan. The AFBR-2CARxxZ enables equipment compliance to these standards detailed in Table 1. The metal housing and shielded design of the AFBR-2CARxxZ minimizes the EMI challenge facing the equipment designer.  For superior EMI performance it is recommended that equipment designs utilize SFP+ cages per SFF 8432. 

## **RF Immunity (Susceptibility)** 

The EMI immunity of the AFBR-2CARxxZ exceeds typical industry standards. 

## **Eye Safety** 

The AFBR-2CARxxZ provides Class 1 (single fault tolerant) eye safety by design and has been tested for compliance with the requirements listed in Table 1. The eye safety circuit continuously monitors the optical output power level and will disable the transmitter upon detecting a condition beyond the scope of Class 1 certification. Such conditions can be due to inputs from the host board (Vcc fluctuation, unbalanced code) or a fault within the transceiver.  US CDRH and EU TUV certificates are listed in table 1. 

## **Flammability** 

The AFBR-2CARxxZ optical cable is made of metal and high strength, heat resistant, chemical resistant and UL 94V-0 flame retardant plastic.

Pull ups can be connected to various power supplies, however the host board design shall ensure that no module contact has voltage exceeding VccT or VccR by 0.5 V nor requires the module to sink more than 3.0 mA current. 

2. Ci is the capacitance looking into the module SCL and SDA contacts 

3. Cb is the total bus capacitance on the SCL or SDA bus.

## **Notes:** 

1. Time from power on or falling edge of TX_DISABLE to when the modulated optical output rises above 90% of nominal (not measurable in the Active Optical Cable) and the Two-Wire interface is available. 

2.  The maximum time between (a) when the near-end AOC-end has TX_DISABLE asserted until (b) RX_LOS is declared/asserted on the far-end AOC-end.  There is also a small delay for the signal transit time through the optical cable, however, this is a small effect: light propagating through fiber ~ 5ns per meter.  A 10 ms interval between assertions of TX_DISABLE is required. 

3.  The maximum time between (a) when the near-end AOC-end has TX_DISABLE negated until (b) RX_LOS is deasserted on the far-end AOC-end. There is also a small delay for the signal to transit time through the optical cable, however, this is a small effect: light propagating through fiber ~ 5 ns per meter
