The lead-free and RoHS-compliant small form factor pluggable (SFP+) transceiver from JDSU improves the performance for 10 Gigabit Ethernet (10 G) applications, and is ideal for high-speed, local area network applications. This transceiver features a highly reliable, 850 nm, oxide, vertical-cavity surface-emitting laser (VCSEL) coupled to an LC optical connector. The transceiver is fully compliant to 10GBASE-SR, 10GBASE-SW and 10 G Fibre Channel specifications, with internal AC coupling on both transmit and receive data signals. The all-metal housing design provides low EMI emissions in demanding 10 G applications and conforms to IPF specifications. An enhanced digital diagnostic feature set allows for real-time monitoring of transceiver performance and system stability, and the serial ID allows for customer and vendor system information to be stored in the transceiver. Transmit disable, loss-of-signal, and transmitter fault functions are also provided. The small size of the transceiver allows for high-density board designs that, in turn, enable greater total bandwidth.

Transmitter

Thetransmitterconverts64B/66BscrambledserialPECLorCMLelectricaldatainto serial optical data compliant with the 10GBASE-SR, 10GBASE-SW or 10 G Fibre channel standard. Transmit data lines (TD+ and TD-) are internally AC coupled, with 100 W differential termination.

Transmitterrateselect(RS1)pin9isassignedtocontroltheSFP+moduletrans-mitterrate.Itisconnectedinternallytoa30kW pull-down resistor. A data signal on this pin does not affect the operation of the transmitter.

An open collector-compatible transmit disable (Tx_Disable) is provided. This pin is internally terminated with a 10 kW resistor to Vcc,T. A logic “1,” or no connec-tion, on this pin will disable the laser from transmitting. A logic “0” on this pin provides normal operation.

The transmitter has an internal PIN monitor diode that ensures constant optical power output, independent of supply voltage. It is also used to control the laser output power over temperature to ensure reliability at high temperatures.

An open collector-compatible transmit fault (Tx_Fault) is provided. The Tx_Fault signal must be pulled high on the host board for proper operation. A logic “1” output from this pin indicates that a transmitter fault has occurred or that the part is not fully seated and the transmitter is disabled. A logic “0” on this pin indicates normal operation.

Receiver

Thereceiverconverts64B/66BscrambledserialopticaldataintoserialPECL/CMLelectrical data. Receive data lines (RD+ and RD-) are internally AC coupled with 100 W differential source impedance, and must be terminated with a 100 W dif-ferential load.

An open collector compatible loss of signal (LOS) is provided. The LOS must be pulled high on the host board for proper operation. A logic “0” indicates that light has been detected at the input to the receiver (see Optical characteristics, Loss of SignalAssert/DeassertTime).Alogic“1”outputindicatesthatinsufficientlighthas been detected for proper operation.

4.2 Package and Handling Instructions

This product is not compatible with any aqueous wash process.

Process plugThePLRXPL-Sx-S43-22-Nopticaltransceiverissuppliedwithaprocessplug.Thisplug protects the transceiver’s 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.

Recommended cleaning and de-greasing chemicalsJDSU recommends the use of methyl, isopropyl and isobutyl alcohols for cleaning.

Do not use halogenated hydrocarbons (trichloroethane, ketones such as acetone, chloroform, ethyl acetate, MEK, methylene chloride, methylene dichloride, phenol, N-methylpyrolldone).

FlammabilityThe housing is made of cast zinc and sheet metal.

4.3 Electrostatic Discharge (ESD)

HandlingNormal 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 groundedbenches,floormats,andwriststraps.

Test and operationIn most applications, the optical connector will protrude through the system chas-sis 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 which may become temporarily saturated during an ESD strike. This could result in a short burst of bit errors. Such an event may requiretheapplicationtoreacquiresynchronizationatthehigherlayers(serializer/deserializer chip).

Operating the product with a power supplyvoltageexceeding4.0voltsmaycompromisethereliabilityoftheproduct,and could result in laser emissions exceeding Class 1 limits.

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 DrugAdministration(21CFR1040).

The use of optical instruments with this product will increase eye hazard.
