Finisar Corporation October 2015 Rev. B1 Page 7 FTLX6811MCC and FTLX6814MCC T-XFP Product Specification VIII. Digital Diagnostics Functions As defined by the XFP MSA1, Finisar XFP transceivers provide digital diagnostic functions via a 2-wire serial interface, which allows real-time access to the following operating parameters: * * * * * * Transceiver temperature Laser bias current Transmitted optical power Received optical power Transceiver supply voltage TEC Temperature It also provides a sophisticated system of alarm and warning flags, which may be used to alert end-users when particular operating parameters are outside of a factory-set normal range. The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller (DDTC) inside the transceiver, which is accessed through the 2-wire serial interface. When the serial protocol is activated, the serial clock signal (SCL pin) is generated by the host. The positive edge clocks data into the XFP transceiver into those segments of its memory map that are not write-protected. The negative edge clocks data from the XFP transceiver. The serial data signal (SDA pin) is bi-directional for serial data transfer. The host uses SDA in conjunction with SCL to mark the start and end of serial protocol activation. The memories are organized as a series of 8-bit data words that can be addressed individually or sequentially. The 2-wire serial interface provides sequential or random access to the 8 bit parameters, addressed from 000h to the maximum address of the memory. For more detailed information, including memory map definitions, please see the XFP MSA documentation1. Receiver Threshold Adjustment The FTLX6811MCC and FTLX6814MCC also provide access to receiver decision threshold adjustment via 2-wire serial interface, in order to improve receiver OSNR performance based on specific link conditions. It is implemented as follows: * * * Rx Threshold of XFP transceivers will be factory-set for optimized performance in non-FEC applications. This will be the default value during both cold start (power-up) and warm start (module reset). The transceiver supports adjustment of Rx Threshold value by the host through register 76d, table 01h. This is intended to be used in FEC applications. Register 76d, table 01h is a volatile memory. Therefore if the transceiver is power-cycled, the register starts up with a value of 00h which corresponds to the default Rx Threshold value. Finisar Corporation October 2015 Rev. B1 Page 8 FTLX6811MCC and FTLX6814MCC T-XFP Product Specification * * The threshold adjustment input value is 2's complement 7 bit value (-128 to +127), with 0 corresponding to default Rx threshold value. Full range of adjustment provides at least a 10% change in Rx threshold from the default value. An increase in RxDTV value sets the threshold closer to the "1" value of the eye. The Default setting is the factory tuned optimized set point and is not necessarily the 50% RxDTV value. Logical "1" Max 50% Min Logical "0" RxDTV SBS suppression, dither tone Set Address 111, bit 1 to "0" to enable tone, "1" to disable dither tone (defaults: frequency = 40kHz , tone is disabled). Please contact your Finisar RSM or PLM if specific amplitudes and frequencies are needed for SBS suppression. Tuning Management Interface for ITU Frequency Grid Applications Implementation of wavelength or frequency tuning is indicated in Serial ID Byte 221 (Table 01h) bit 1. Data Address 221 (Table 01h) Bit 1 Description Wavelength or frequency tunability implemented The Finisar tunable XFP supports both wavelength and frequency tuning (as specified in INF-8077i), the wavelength tuning support is indicated by the transceiver description encoded in Serial ID Byte 138 bits 2 and 3.

B1 Page 9 FTLX6811MCC and FTLX6814MCC T-XFP Product Specification Upon a power up, the module will go to a default wavelength (Finisar default channel is 1549.716nm) or the last channel set by the host. If Tx_DIS is asserted upon power up, the laser will be disabled and the set wavelength will be cleared. Once the Tx_DIS is deasserted, the firmware will maintain the laser in an off state until the host sets the desired ITU channel. If the module is powered-down before the ITU channel was set and TX_DIS de-asserted, the module will re-start at the default channel. See the following startup channel flowchart. Flow Chart of Startup Channel A desired wavelength can be commanded by the user by writing into Bytes 72 (MSB) and 73 (LSB). Wavelength control command: Address 72 (MSB) & 73 (LSB) 74 (MSB) & 75 (LSB) Bit All Name Wavelength Set All Wavelength Error Description User input of Wavelength set point (in units of 50 pm) Monitor of Current Wavelength Error (in units of 5 pm) Thus for instance a target wavelength of 1556.55 nm would correspond to 79h (MSB) written to Byte address 72 and 9Bh (LSB) written to Byte address 73. Alternatively a desired frequency channel can be commanded by the user by writing into Bytes 112 (MSB) and 113 (LSB). Finisar Corporation October 2015 Rev.
