Compliance
The JDSU JSH-12L1DD1 SFP transceivers are hot-pluggable, 3.3 V duplex-LC transceivers that provide a high-speed serial link at a signaling rate of up to 2.125 Gbps. They are designed for use in ANSI Fibre Channel and Gigabit Ethernet applications. These transceives provide the LC optical receptacle that is compatible with the industry-standard LC connector. The transceiver consists of an optical subassembly housing the transmitter and receiver, and an electrical subassembly. All are packaged together with a top metal cover and bottom shield. The optical subassembly consists of two parts. The transmitter side has a high-performance, 1310 nm, back-facet monitor. The receiver side has an InGaAs PIN and a preamplifier. The digital diagnostic monitoring (DDM) interface uses the same two-wire serial ID interface defined in the SFP MSA specification. The standard serial ID information is located at address A0h. Using address A2h, the user can monitor transceiver parameters, including temperature, voltage, laser bias current, laser power, and receiver power. Alarms and warnings are provided when the monitored parameters exceed predefined threshold values. All transceivers include a loss-ofsignal-detect circuit, which provides a TTL logic high output when an unusable input optical signal level is detected.

Digital Diagnostic Monitoring and Serial ID Operation
The JSH-12L1DD1 is equipped with a two-wire serial management processor/EEPROM used to store information about the type and identification of the transceiver, as well as real-time digitized information relating to transceiver performance. See the SFF Committee document SFF-8472 Rev. 10.3, dated December 1, 2007, for memory/address organization of the identification data and digital diagnostic data. The enhanced digital diagnostics feature monitors five key transceiver parameters that are internally calibrated and should be read as absolute values and interpreted as follows:
Transceiver Temperature in Degrees Celsius: Internally measured. Represented as a
16 bit signed two's complement value in increments of 1/256C from -40 to +85C with LSB equal to 1/256C. Accuracy is 5C over the specified operating temperature and voltage range.
Vcc/Supply Voltage in Volts: : Internally measured. Represented as a 16 bit unsigned integer with the voltage defined as the full 16-bit value (0 - 65535) with LSB equal to 100 uV with a measurement range of 0 to +6.55 V. Accuracy is 3 percent of nominal value over the specified operating temperature and voltage ranges. TX Bias Current in mA: Represented as a 16-bit unsigned integer with current defined as the full 16-bit value (0 - 65535) with LSB equal to 2 uA with a measurement range of 0 - 131 mA. Accuracy is 10 percent of nominal value over the specified operating temperature and voltage ranges. TX Output Power in mW: Represented as a 16-bit unsigned integer with the power defined as the full 16-bit value (0 - 65535) with LSB equal to 0.1 uW. Accuracy is 2 dB over the specified temperature and voltage ranges over the range of -8.2 dBm to 0.5 dBm. Data is not valid when transmitter is disabled. RX Received Optical Power in mW: Represented as average power as a 16-bit un-
signed integer with the power defined as the full 16-bit value (0 - 65535) with LSB equal to 0.1 uW. Accuracy is 3 dB over the specified temperature and voltage ranges over the power range of -14.5 dBm to 0.5 dBm.
Reading the data
The information is accessed through the SCL and SDA connector pins of the module. The specification for the EEPROM contains all the timing and addressing information required for accessing the data. The device address used to read the Serial ID data is 1010000X(A0h), and the address to read the diagnostic data is 1010001X(A2h). Any other device addresses will be ignored. MOD_ABS, pin 6 on the transceiver, is connected to Logic 0 (ground) on the transceiver.

10
SCL, pin 5 on the transceiver, is connected to the SCL pin of the Management Processor/EEPROM. SDA, pin 4 on the transceiver, is connected to the SDA pin of the Management Processor/EEPROM. The EEPROM Write Protect pin is internally tied to ground with no external access, allowing write access to the customer-writable field (bytes 128 - 247 of address 1010001X). Note: address bytes 0 - 27 are not write protected and may cause diagnostic malfunctions if written over.
Decoding the data
The information stored in the EEPROM, including the organization and the digital diagnostic information, is defined in SFF-8472 Revision 10.3, dated December 1, 2007.

Package and Handling Instructions
Process plug
The JSH-12L1DD1 is supplied with a dust plug that protects the transceiver optics during standard manufacturing processes by preventing contamination from air borne particles. Note: It is recommended that the dust cover remain in the transceiver whenever an optical fiber connector is not inserted.
Flammability
The JSH-12L1DD1 housing is made of cast zinc and sheet metal.
Electrostatic Discharge (ESD)
Handling
Normal ESD precautions are required during the handling of this module. This transceiver is shipped in ESD protective packaging. It should be removed from the packaging and handled only in an ESD protected environment utilizing standard grounded benches, floor mats, and wrist straps.
Test and operation
In most applications, the optical connector will protrude through the system chassis and be subjected to the same ESD environment as the system. Once properly installed in the system, this transceiver should meet and exceed common ESD testing practices and fulfill system ESD requirements. Typical of optical transceivers, this module's receiver contains a highly sensitive optical detector and amplifier that may become temporarily saturated during an ESD strike. This could result in a short burst of bit errors. Such an event might require the application to reacquire synchronization at the higher layers (serializer/ deserializer chip).
Electromagnetic Interference (EMI) and Immunity
To assist customers in managing overall equipment EMI performance, these transceivers are compatible with the industry-standard SFP cage, which provides protection for EMI emission and EMI susceptibility. All transceivers comply with FCC Class B limits.

Eye Safety
The JDSU JSH-12L1DD1 1310 nm, laser-based transceivers are Class 1 laser products. They conform to FDA regulations 21 CFR 1040.10 and 1040.11 laser safety requirements,, including deviations pursuant to Laser Notice No. 50, dated July 26, 2001. They are also certified to comply with IEC standards 60825-1, 60825-2, and 60950, as well as CDHR. The transceivers are UL Listed and are eye safe when operated within the limits of these specifications. Operating this product in a manner inconsistent with intended usage and specification may result in hazardous radiation exposure.
Caution
Tampering with this laser based product or operating this product outside the limits of this specification may be considered an act of manufacturing, and will require, under law, recertification of the modified product with the U.S. Food and Drug Administration (21 CFR 1040). The use of optical instruments with this product will increase eye hazard.
