www.lumentum.com 2

The lead-free and RoHS-compliant small form factor pluggable (SFP+) transceiver from

Lumentum 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 specications, 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 specications. 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.

Section 1 Functional Description

The PLRXPL-Sx-S43-22-N 10 G SFP+ 850 nm optical transceiver

is designed to transmit and receive 64B/66B scrambled 10 G

serial optical data over 50/125 µm or 62.5/125 µm multimode

optical ber.

Transmitter

The transmitter converts 64B/66B scrambled serial PECL or CML

electrical data into 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 Ω differential termination.

Transmitter rate select (RS1) pin 9 is assigned to control the SFP+

module transmitter rate. It is connected internally to a 30 kΩ

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 kΩ resistor

to Vcc,T. A logic “1,” or no connection, 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

The receiver converts 64B/66B scrambled serial optical data into

serial PECL/CML electrical data. Receive data lines (RD+ and RD-)

are internally AC coupled with 100 Ω differential source

impedance, and must be terminated with a 100 Ω

differential load.

Receiver Rate Select (RS0) pin 7 is assigned to control the SFP+

module receiver rate. It is connected internally to a 30 kΩ

pull-down resistor. A data signal on this pin has no affect on the

operation of the receiver.

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 Signal Assert/

Deassert Time). A logic “1” output indicates that insufcient light

has been detected for proper operation.

Figure 2 Recommended application schematic for the 10 G SFP+ optical transceiver

Notes :

 Power supply filtering components should be placed as close to the Vcc pins of the host connector as possible for optimal performance.

 PECL driver and receiver components will require biasing networks. Please consult application notes from suppliers of these components. CML I/O on the PHY are

supported. Good impedance matching for the driver and receiver is required.

 SDA and SCL should be bi-directional open collector connections in order to implement serial ID in JDSU SFP+ transceiver modules.

 R1/R2 and R3/R4 are normally included in the output and input of the PHY. Please check the application notes for the IC in use.

* Transmission lines should be 100 Ω differential traces. Vias and other transmission line discontinuities should be avoided. In order to meet the host TP1 output jitter and TP4

jitter tolerance requirements it is recommended that the PHY has both transmitter pre-emphasis to equalize the transmitter traces and receiver equalization to equalize the

receiver traces. With appropriate transmitter pre-emphasis and receiver equalization, up to 8 dB of loss at 5 GHz can be tolerated.

** R5 and R6 are required when an Open Collector driver is used in place of CMOS or TTL drivers. 5 kΩ value is appropriate.

*** The value of Rp and Rq depend on the capacitive loading of these lines and the two wire interface clock frequency. See SFF-8431. A value of 10 kΩ is appropriate for 80 pF

capacitive loading at 100 kHz clock frequency.

5. Distances, shown in the “Link Length” table, are calculated for worst-case ber and transceiver characteristics based on the optical

and electrical specications shown in this document using techniques specied in IEEE 802.3. These distances are consistent with

those specied for 10GBASE-SR and 10GBASE-SW. In the nominal case, longer distances are achievable.

6. The maximum transmitter output power is the lesser of the Class 1 laser eye safety limit and -1 dBm (the maximum receiver input

power limit per the IEEE 802.3 Clause 52 specication).

7. Sensitivity is for informational purposes only.

8. The data pattern for the total jitter measurement is one of IEEE 802.3 Clause 52.9 Pattern 1, Pattern 3, or valid 64B/66B data trafc.

9. 99% jitter is as dened in SFF-8431 Revision 3.2. 99% jitter has the same denition as “all but 1% for jitter” as used in IEEE 802.3

Clause 52.9.9 and is dened as the time from the 0.5th to the 99.5th percentile of the jitter histogram.

temperature and voltage ranges.

TX Output Power in mW: Represented as a 16-bit unsigned

integer with the power dened as the full 16-bit value

(0 – 65535) with LSB equal to 0.1 uW. Accuracy is ± 2 dB over

the specied temperature and voltage ranges over the range of

−7 dBm to −1 dBm. Data is not valid when transmitter is disabled.

RX Received Optical Power in mW: Represented as average

power as a 16-bit unsigned integer with the power dened as the

full 16-bit value (0 – 65535) with LSB equal to 0.1 uW. Accuracy

is ± 3 dB over the specied temperature and voltage ranges over

the power range of -12 dBm to 0 dBm.

Reading the data

The information is accessed through the SCL and SDA connector

pins of the module. The SFF-8431 Revision 3.2 specication

contains all the timing and addressing information required for

accessing the data in the EEPROM.

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.

SCL, pin 5 on the transceiver, is connected to the SCL pin of

the EEPROM.

SDA, pin 4 on the transceiver, is connected to the SDA pin of

the EEPROM.

The EEPROM Write Protect pin is internally tied to ground with

no external access, allowing write access to the customer-

writable eld (bytes 128 – 247 of address 1010001X).

Note: address bytes 0 – 127 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 dened in the Small

Form Factor Committee document SFF-8472 Revision 10.3, dated

December 1, 2007.

4.2 Package and Handling Instructions

This product is not compatible with any aqueous wash process.

Process plug

The PLRXPL-Sx-S43-22-N optical transceiver is supplied with a

process plug. This plug 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 ber connector is not inserted.

Recommended cleaning and de-greasing chemicals

Lumentum 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).

Flammability

The housing is made of cast zinc and sheet metal.

4.3 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,

oor 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 fulll system ESD requirements.

Typical of optical transceivers, this module’s receiver contains a

highly sensitive optical detector and amplier which may become

temporarily saturated during an ESD strike. This could result in a

short burst of bit errors. Such an event may require the

application to reacquire synchronization at the higher layers

(serializer/deserializer chip).

4.4 Laser Safety

The transceiver is certied as a Class 1 laser product per

international standard IEC 60825-1:2007 2nd edition and is

considered non-hazardous when operated within the limits of

this specication.

The transceiver complies with 21 CFR 1040.10 except for

deviations pursuant to Laser Notice No. 50 dated June 24, 2007.

Caution

Operating this product in a manner inconsistent with intended

usage and specications may result in hazardous radiation

exposure.

Use of controls or adjustments or performance of procedures

other than these specied in this product data sheet may result

in hazardous radiation exposure.

Tampering with this laser product or operating this product

outside the limits of this specication may be considered an ‘act

of manufacturing’ and may require recertication of the modied

product.

Viewing the laser output with certain optical instruments, such as

eye loupes, magniers, microscopes, within a distance of 100 mm

may pose an eye hazard.
