Data Sheet

PPOC-4102-DIn2

The AFCT-57J5ATPZ optical transceiver supports highspeed serial links over singlemode optical fiber at signaling rates up to Gb/s. Compliant with Small Form Pluggable SFP Multi Source Agreement MSA mechanical and electrical specifications, ANSI Fibre Channel FC-PI-3 and compatible with IEEE for gigabit applications.

As an enhancement to the conventional SFP interface defined in SFF-8074i, the AFCT-57J5ATPZ is compliant to SFF-8472 digital diagnostic interface for SFP . Using the 2-wire serial interface defined in the SFP MSA, the AFCT-57J5ATPZ provides real time temperature, supply voltage, laser bias current, laser average output power and received average input power. This information is in addition to the conventional SFP data. The digital diagnostic interface also adds the ability to disable the transmitter TX_DISABLE , monitor for Transmitter Faults TX_FAULT , monitor for Receiver Loss of Signal RX_LOS .

Installation

The AFCT-57J5ATPZ can be installed in any SFF-8074i compliant Small Form Pluggable SFP port regardless of host equipment operating status. The AFCT-57J5ATPZ 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 .

Digital Diagnostic Interface and Serial Identification

The 2-wire serial interface is based on ATMEL AT24C01A series EEPROM protocol and signaling detail. Conventional SFP EEPROM memory, bytes 0-255 at memory address 0xA0, is organized in compliance with SFF-8074i. 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.

The I2C accessible memory page address 0xB0 is used internally by SFP for the test and diagnostic purposes and it is reserved.

Predictive Failure Identification

The AFCT-57J5ATPZ 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 associated with observing 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. AFCT-57J5ATPZ 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. AFCT-57J5ATPZ 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.

Component Monitoring

Component evaluation is a more casual use of the AFCT-57J5ATPZ real-time monitors of Tx_Bias, Tx_Power, Vcc, Temperature and Rx_Power. Potential uses are as debugging aids for system installation and design, and transceiver parametric evaluation for factory or field qualification. For example, temperature per module can be observed in high density applications to facilitate thermal evaluation of blades, PCI cards and systems.

Caution

There are no user serviceable parts nor maintenance requirements for the AFCT-57J5ATPZ. All mechanical adjustments are made at the factory prior to shipment. Tampering with, modifying, misusing or improperly handling the AFCT-57J5ATPZ 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 AFCT-57J5ATPZ to a light source not compliant with ANSI FC-PI or IEEE specifications, 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 re-certify and re-identify the laser product under the provisions of U.S. 21 CFR Subchapter J and TUV.

Regulatory Compliance

The AFCT-57J5ATPZ 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 AFCT-57J5ATPZ 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 precautions. These include using of grounded wrist straps, workbenches 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 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 AFCT-57J5ATPZ’s compliance to these standards is detailed in Table The metal housing and shielded design of the AFCT-57J5ATPZ minimizes the EMI challenge facing the equipment designer.

EMI Immunity Susceptibility

Due to its shielded design, the EMI immunity of the AFCT57J5ATPZ exceeds typical industry standards.

Flammability
