The transceiver complies with Fibre Channel FC-PI-5 1600-M5x-SN variants when the rate-select inputs are pulled high, and complies with 800-M5x-SN and 400-M5x-SN-I when the rate-select inputs are pulled low. The transceiver supports the Enhanced Small Form Factor Pluggable Module SFP+ specification SFF-8431 Rev. 4.1 for the electrical interface, SFF-8432 Rev. 5.0 for the mechanical interface, and SFF-8472 Rev. 11.0 for the management interface. Figure 1 shows a block diagram. VCCT VEET VCCR VEER Receiver ROSA The receiver converts incoming DC-balanced serial NRZ 4.25 to 14.025 Gbps line rate optical data into serial electrical signals. The amplified signal is passed to a signal conditioning IC that provides clock and data recovery. The receive CDR function generates a clock that is at the same frequency as the incoming data bit rate of the optical data input. The clock is phase aligned by a PLL that samples the data in the center of the data eye pattern. The CDR contains a lock detect circuit that indicates successful locking of the PLL onto the incoming data. RD– CDR TIA SCL MCU SDA TD– Laser Driver CDR TD+ The amplified signal is output directly on the RD+ and RD− pins as a 100 Ω CML signal. TOSA RX_LOS TX_FAULT VEET VEET VEET VCCT Low-Speed Signaling TX_DIS RS0 RS1 The Tx signal conditioner’s output is input to the laser driver circuit which transforms the small swing digital voltage to an output modulation that drives a VCSEL laser. The optical signal is engineered to meet the 16 G FC when the rate-select inputs are pulled high and 8 G and 4 G FC specifications when the rate-select inputs are pulled low. Closed-loop control of the transmitted laser power over temperature and voltage variations is provided. The laser is coupled to a multimode optical fiber through an industry-standard LC optical connector. Transceiver Ground Power Supply Sequence/ In-Rush Control Circuit RD+ Inside the module, the differential signal passes through a signal conditioner with equalization that compensates for input data stream losses and deterministic jitter. The transmit CDR function generates a clock that matches the incoming data bit rate frequency of the electrical data input. The clock is phase aligned by a phase locked loop (PLL) that samples the data in the center of the data eye pattern. MOD_ABS Figure 1. JDSU SFP+ optical transceiver functional block diagram Low-speed signaling is based on low-voltage TTL (LVTTL) operating at a nominal voltage of 3.3 V. Hosts should use a pull-up resistor connected to VCC 3.3 V on the 2-wire interface SCL, SDA, and all low-speed outputs based on the SFF 8431 Rev. 4.1 requirements. The transceiver has several low-speed interface connections. These connections include: transmitter fault (Tx_Fault), transmitter disable (Tx_Disable), rate select (RS0 and RS1), module absent (Mod_ABS), receive loss of signal (Rx_LOS), and a 2-wire serial interface clock (SCL) and data (SDA). Low-Speed Interface Connections Definition SCL/SDA 2-wire serial interface clock and data line. Tx_Fault Output pin. When asserted high, indicates that the module has detected a transmitter fault condition related to laser operation or safety. The transceiver supports the SFI electrical interface. The electrical interface is based on a high-speed, low-voltage logic AC-coupled limiting interface with a 100 Ω nominal differential impedance. Tx_Disable Input pin. When asserted high or left open, the transmitter output is turned off. When Tx_Disable is asserted low or grounded, the module transmitter is operating normally. Transmitter RS0 and RS1 Input pins. Pulled low to VEET with > 30 kΩ resistors in the module. When RS1 is asserted low, the transmitter CDR is bypassed and the module transmitter is optimized for low-speed operation, 8.5 Gbps or lower. When RS0 is asserted low, the receiver CDR is bypassed and the module receiver is optimized for low-speed operation, 8.5 Gbps or lower. Mod_ABS Output pin. Asserted high when the SFP+ module is absent and is pulled low when the SFP+ module is inserted. Rx_LOS Output pin. Asserted high when insufficient optical power for reliable signal reception is received. The transmitter path converts serial NRZ electrical data from 4.25 to 14.025 Gbps line rates to a standard compliant optical signal. The transmitter accepts a 100 Ω differential 180 mV peak-to-peak to 700 mV peak-to-peak CML electrical signal on TD– and TD+ pins. www.jdsu.com 2 16 G FC Compliant 850 nm SFP+ Limiting Transceiver — JSH Series 3.1 Rx_LOS Mod_ABS Tx_Fault OUTPUT Tx_Disable RS1 2 RS0 SCL/SDA INPUT GND VEER GND VEET +3.3 V VCCR +3.3 V VCCT POWER Toward ASIC SFP+ modules are hot pluggable and active connections are powered by individual power connections for the transmitter (VCCT) and the receiver (VCCR).

Electrical The electrical connector is a 20-way, two-row PCB edge connector. The customer connector is Tyco/AMP Part No. 188247 or equivalent. www.jdsu.com 9 16 G FC Compliant 850 nm SFP+ Limiting Transceiver — JSH Series Section 4 Other Related Information Test and Operation Section 4.1 Packing and Handling Instructions Section 4.2 Electrostatic Discharge Section 4.3 Laser Safety 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. 4.1 Package and Handling Instructions Connector Covers The transceiver is supplied with an LC duplex receptacle. The connector plug supplied protects the connector during standard manufacturing processes and handling by preventing contamination from dust, aqueous solutions, body oils, or airborne particles. Note: It is recommended that the connector plug remain on whenever the transceiver optical fiber connector is not inserted. Recommended Cleaning and Degreasing Chemicals JDSU recommends the use of methyl, isopropyl, and isobutyl alcohols for cleaning. Do not use halogenated hydrocarbons, such as trichloroethane or ketones such as acetone, chloroform, ethyl acetate, MEK, methylene chloride, methylene dichloride, phenol, and N-methylpyrrolidone. Typical of optical transceivers, this module’s receiver contains a highly sensitive optical detector and amplifier which may become temporarily saturated during an ESD strike. This could result in a short burst of bit errors. Such an event might require that the application re-acquire synchronization at the higher layers (for example, a serializer/deserializer chip). 4.3 Laser Safety The transceiver is certified as a Class 1 laser product per international standard IEC 60825-1:2007 2nd edition and is considered nonhazardous when operated within the limits of this specification.
