PRODUCT DESCRIPTIONS

OlinkPhotonics’s Small Form Factor Pluggable (SFP+) OLLB0010-CN Electrical loopback modules provide an effective way of testing the SFP+ ports in the host system by looping back the electrical signal (no optics are included). The units provide basic Serial ID information that attempts to mimic a shortwave GigE /1G/2G FC SFP+ transceiver 4G FC, 8G FC and 10Gb/s Ethernet/FC for manufacturing testing. In addition, the user can query the number of power-up/insertion cycles via the Digital Diagnostics Monitoring Interface in order to ensure optimum module reliability and ascertain device’s useful life.

PIN DESCRIPTIONS

Notes:

1. Should be pulled up with 4.7k – 10kohms on host board to a voltage between 2.0V and 5.5V.

MOD_DEF(0) pulls line low to indicate module is plugged in.

2. LOS is pulled low within the module and therefore will always indicate a received signal.

ABSOLUTE MAXIMUM RATINGS

OlinkPhotonics’s SFP+ transceivers have a power supply voltage range of 3.0 V to 3.60V and an

extended operating temperature range from –40°C to 85°C.

ELECTRICAL CHARACTERISTICS (TOP = -40 to 85 ° C, VCC = 3.0 to 3.60 Volts)

Testing Methodology per SFF-8431. Rev 2.2

Notes:

1. Non condensing.

2. Into 100 ohms differential termination.

3. LOS is pulled low internally, and will therefore always indicate a received signal.

4. A digital power cycle counter can be found at memory location 254 (MSB)-255(LSB) at device

address A2.

SERIAL COMMUNICATIONS PROTOCOL

Olink’s SFP+ transceivers support the 2-wire serial communication protocol as defined in the SFF-8472. It is very closely related to the EEPROM defined in the GBIC standard, with the same electrical specifications.

The standard SFP+ serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information.

Additionally, Olink SFP+ transceivers provide a enhanced digital diagnostic monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage. It also defines a sophisticated system of alarm and warning flags, which alerts end-users when particular operating parameters are outside of a factory set normal range.

SFF-8472 defines a 256-byte memory map in EEPROM that is accessible over a 2-wire serial interface at the 8 bit address 1010000X (A0h). The digital diagnostic monitoring interface makes use of the 8 bit address 1010001X (A2h), so the originally defined serial ID memory map remains unchanged. The Insertion Cycle Counter is placed in this area, with Byte 120 containing the MSB, Byte 121 the LSB. The interface is identical to, and is thus fully backward compatible with both the GBIC Specification and the SFP Multi Source Agreement. The complete interface is described in Olink Application Note AN-2030: “Digital Diagnostics Monitoring Interface for SFP Optical Transceivers”.

The (OLLB0010-CN) contains additional feature called a power cycle counter. This value is a 2-byte number between 0 and 65535. This counter is located at memory address 254 (MSB) and 255 (LSB) on device address A2. This counter will be automatically incremented every time the transceiver is power cycled. The transceiver can not tell the different between hot swap insertion and system power up. The counter

will maximize at 65535 and will not roll over. The transceiver will not take any action due to the value of this counter. This is only provided as an indicator to the cycle age of the transceiver for the user.

The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller (DDTC) inside the transceiver, which is accessed through a 2-wire serial interface. When the serial protocol is activated, the serial clock signal (SCL, Mod Def 1) is generated by the host. The positive edge clocks data into the SFP transceiver into those segments of the EEPROM that are not write-protected. The negative edge clocks data from the SFP transceiver. The serial data signal (SDA, Mod Def 2) 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.
