I2C is incredibly popular because it uses only 2 wires, and like we said, multiple devices can share those wires, making it a great way to connect tons of sensors, drivers, expanders, without using all the microcontroller pins. The only bad news about I2C is that each I2C device must have a unique address - and the addresses only range from 0 to 127 (aka 0 to. The pins we are interested in on the SFP/SFP+ are: Pin1: All VeeT or VeeR pins are ground, you only need to connect to one as they are connected internally in the SFP. Pin 15 and Pin 16 both require +3.3V. Pin 4: MOD-Def (2) - data line of i2c serial interface. Pin 5: MOD-Def (1) - clock line of i2c serial interface. SFP proper address to read length. According to SFF-8472, there are 6 addresses (14 to 19) in table A0 for link length. And when I read a couple of SFP modules trough I2C, I see that more than one of these addresses contain value other than 0.

While I certainly succeeded in changing the configuration to show the level with all 4 LEDs (in 0xDB register), I found it trick to reliably detect when it needed to be reconfigured (esp. given the tight timing window involved). I. Channel Speed register 62. Added byte 62 to the table. Added value 20h in byte 13, Table 5-6 for Rate Select implementation based on PMDs. Modified name and definition of byte 19, in A0h to include cable length in base and multiplier format. Added Table 6-1. Added a High-Power Class declaration bit 6, byte 64 in Table 8-3. You need to load module i2c-dev for this. Each registered i2c adapter gets a number, counting from 0. You can examine Well, you are all set up now. You can now use SMBus commands or plain I2C to communicate with your device. SMBus commands are preferred if the device supports them. SFP proper address to read length. According to SFF-8472, there are 6 addresses (14 to 19) in table A0 for link length. And when I read a couple of SFP modules trough I2C, I see that more than one of these addresses contain value other than 0. I understand here (from SFF-8472) the 255 means supported length is greater than 254 x 100 meters, and. 1000BASE-T1 SFP Module User Manual 13 3.3.2 I2C map register Memory Map (read only registers): Data Bytes Byte Number Comment 0x03 0 Identifier SFP 0x04 1 Ext.

Each registered i2c adapter gets a number, counting from 0. You can examine Well, you are all set up now. You can now use SMBus commands or plain I2C to communicate with your device. SMBus commands are preferred if the device supports them. Judging from my emails, it is quite clear that the I2C bus can be very confusing for the newcomer. I have lots of examples on using the I2C bus on the The master can continue to send data bytes to the slave and these will normally be placed in the following registers because the slave will automatically. SFP I2C connection. Hello, I am confused about how to connect the SFP in my Zynq Ultrascale MPSOC board (ZCU102). And I cannot find useful information about how to install it. The SFP I have is: DM7041-R What I want to do, is very simple. I want to send UDP packets through the SFP from my FPGA to a PC. To start with, I found in the schematic an. Separate code for read/write and register read/write Same i2c calls implemented twice, harder to maintain (optoe combines them) Separate code for SFP and QSFP SFP paging logic should be same as QSFP (after dealing with 2nd I2C addr) optoe combines i2c addr and paging, for SFP and QSFP, into one translate routine. SFP Control & Register Map. Thread starter gavin23; Start date Dec 3, 2010; Status Not open for further replies.

Could be very useful to include the feature to make that the Mikrotik Routers/Swithches with SFP/SFP+ ports be able to do sequential Single-Byte reads to obtain the transceiver specs and ddm from the EEPROM tables A0h/A2h for transceivers like GPON ONU SFP and others than only supports Single-Byte Reads and not multi-bytes reads (255 Bytes. Pluggable Input / Output Solutions. Introduction. The pluggable I/O interface offers significant advantages as a high speed I/O inter-connect. The Ganged SFP product line allows for single row, high density port designs to maximize the horizontal I/O space. There is a set of standard bytes in the SFP that is access via the I2C. This info is defined by the MSA SFF 8472 spec. So what we are trying to read is some of the bytes accessible via I2C address 0xA0 (see figure 3.1 of the SFP spec). Specifically, bytes 3 – 10 should provide the information on whether you have a SFP or SFP+ module installed. The register controls whether i2c responds with a ACK or NACK when it receives an I2C General Call address. ic_enable_status This register is used to report the i2c hardware status when the IC_ENABLE register is set from 1 to 0; that is, when i2c is disabled. If IC_ENABLE has been set to 1, bits 2:1 are forced to 0, and bit 0 is forced to 1. 6. Load the register address in the SSPxBUF register. 7.

I²C stands for Inter-integrated-circuit. It is a serial communication interface with a bidirectional two-wire synchronous serial bus normally consists of two wires – SDA (Serial data line) and SCL (Serial clock line) and pull-up resistors. They are used for projects that require many different parts (eg. sensors, pin, expansions, and drivers. The SFP+ low speed electrical interface has several enhancements over the classic SFP interface (INF-8074i), but the SFP+ host can be designed to also support most legacy SFP modules. This specifica-tion ensures compatibility between host masters and SFP+ SCL/SDA lines and compatibility with I2C. The SFP+ (enhanced small form-factor pluggable) is an enhanced version of the SFP that supports data rates up to 16 Gbit/s.The SFP+ specification was first published on May 9, 2006, and version 4.1 published on July 6, 2009. SFP+ supports 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. It is a popular industry format. defined in the GBIC specification, as well as the SFP MSA. Both specifications define a 256-byte memory map in EEPROM that is accessible over a two-wire serial inter-face at the 8-bit address 1010000X (0xA0). The digital diagnostic monitoring interface makes use of the 8-bit address 1010001X (0xA2), so the originally defined serial. The Cisco SFP-10G-SR-X is a multirate * 10GBASE-SR, 10GBASE-SW and OTU2/OTU2e module for extended operating temperature range. It supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade Multimode Fiber (MMF). I2C EEPROM Driver Kernel Configuration. There are higher layer drivers that allow the I2C driver to be used to access other devices such as the I2C serial EEPROM on the ML507 board. The following steps may be used to enable the driver in the kernel configuration. From the device drivers menu, select Misc devices. Source Agreement) document dated September 14th, 2000. It is also compliant with the proposed DWDM SFP MSA Document. This interface allows read-only access to two separate memory locations starting at 1010000X (A0h) and 101000X (A2h). Table 3 and Table 4 contain address descriptions and register mapping information for both memory locations.
