AFBR-703SDDZ 10Gb/1Gb Ethernet, 850nm SFP+ Transceiver

Data Sheet

The Avago AFBR-703SDDZ transceiver is part of a family of SFP+ products. This transceiver utilizes Avago’s 850nm VCSEL and PIN Detector technology to provide an IEEE 10Gb Ethernet design compliant with the 10GBASE-SR standard and allows the operation at 1.25GBd for Gigabit Ethernet application. The AFBR-703SDDZ transceiver is designed to enable 10Gb Ethernet 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. These specifications are referred to as SFP+ to recognize these enhancements to previous SFP specifications used for lower speed products. Avago Technologies is an active participant in the SFF Committee specification development activities.

Installation

The AFBR-703SDDZ transceiver 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-703SDDZ is hot-pluggable, allowing the module to be installed while the host system is operating and on-line. Upon insertion, the transceiver housing makes initial contact with the host board SFP cage, mitigating potential damage due to Electro-Static Discharge ESD .

By selecting TX rate select to Gbps operation, the module TX performance complies with the extinction ratio and output power level in 1000BASE-SX specifications.

Likewise RX performance complies with the sensitivity performance in the 1000BASE-SX specifications by selecting RX rate select to Gbps operation.

The rate select can be done through either the hardware pins or the software access to the A2h page of EEPROM map. The user can refer to the Appendix for details of rate select.

Digital Diagnostic 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. New digital diagnostic information, bytes 0-255 at memory address 0xA2, is compliant to SFF-8472. The new diagnostic information provides the opportunity for Predictive Failure Identification, Compliance Prediction, Fault Isolation and Component Monitoring.

Predictive Failure Identification

The AFBR-703SDDZ predictive failure feature allows a host to identify potential link problems before system performance is impacted. Prior identification of link problems enables a host to service an application via “fail over”to a redundant link or replace a suspect device, maintaining system uptime in the process. For applications where ultra-high system uptime is required, a digital SFP provides a means to monitor two real-time laser metrics with laser degradation and predicting failure average laser bias current Tx_Bias and average laser optical power Tx_Power .

Compliance Prediction

Compliance prediction is the ability to determine if an optical transceiver is operating within its operating and environmental requirements. AFBR-703SDDZ devices provide real-time access to transceiver internal supply voltage and temperature, allowing a host to identify potential component compliance issues. Received optical power is also available to assess compliance of a cable plant and remote transmitter. When operating out of requirements, the link cannot guarantee error free transmission.

Fault Isolation

The fault isolation feature allows a host to quickly pinpoint the location of a link failure, minimizing downtime. For optical links, the ability to identify a fault at a local device, remote device or cable plant is crucial to speeding service of an installation. AFBR-703SDDZ real-time monitors of Tx_Bias, Tx_Power, Vcc, Temperature and Rx_ Power can be used to assess local transceiver current operating conditions. In addition, status flags TX_DISABLE and Rx Loss of Signal LOS are mirrored in memory and available via the two-wire serial interface.

Regulatory Compliance

The AFBR-703SDDZ complies with all applicable laws and regulations as detailed in Table Certification level is dependent on 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 AFBR-703SDDZ is compatible with ESD levels found in typical manufacturing and operating environments as described in Table 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 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 transceiver 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 transceiver may be subject to system level ESD requirements.

Electromagnetic Interference EMI

Equipment incorporating 10 gigabit transceivers is typically subject to regulation by the FCC in the United States, CENELEC EN55022 CISPR 22 in Europe and VCCI in Japan. The AFBR-703SDDZ enables equipment compliance to these standards detailed in Table The metal housing and shielded design of the AFBR-703SDDZ minimizes the EMI challenge facing the equipment designer. For superior EMI performance it is recommended that equipment designs utilize SFP+ cages per SFF

RF Immunity Susceptibility

Due to its proprietary bulk optics TOSA and ROSA design, the EMI immunity of the AFBR-703SDDZ exceeds typical industry standards.

Eye Safety

The AFBR-703SDDZ provides Class 1 single fault tolerant eye safety by design and has been tested for compliance with the requirements listed in Table 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

Flammability

The AFBR-703SDDZ optical transceiver is made of metal and high strength, heat resistant, chemical resistant and UL 94V-0 flame retardant plastic.
