The lead-free and RoHS-compliant small form factor pluggable (SFP+) transceiver
from JDSU improves the performance for 8 Gigabit Fibre Channel (8GFC)
applications, and is ideal for high-speed, storage area network applications. This
transceiver features a highly reliable, distributed-feedback (DFB) laser coupled to
an LC optical connector. The transceiver is fully compliant to the FC-PI-4 800-SMLC-L variant and is compatible with 400-SM-LC-L and 200-SM-LC-L variants. It
is fully compatible with SFP+ specifications at 8.5 G, 4.25 G and 2.125 G bit rates,
with internal AC coupling on both transmit and receive data signals. The all-metal
housing design provides low EMI emissions in demanding 8.5 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 system
designs that, in turn, enable greater total bandwidth.

Section 1
Functional Description
The JSH-85L3Ax1-10 8.5 G SFP+ 1310 nm optical transceiver is designed to transmit
and receive 8B/10B scrambled 8.5 G serial optical data over standard single-mode
optical fiber.
Transmitter
The transmitter converts 8B/10B scrambled serial PECL or CML electrical data into
serial optical data compliant with the 800-SM-LC-L variant of the 8 G Fibre Channel
standard. Transmit data lines (TD+ and TD-) are internally AC coupled, with 100 W
differential termination.
Transmitter rate select (RS1) pin 9 is assigned to control the SFP+ module transmitter rate. It is connected internally to a 30 kW 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 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 8B/10B 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 W differential load.
Receiver Rate Select (RS0) pin 7 is assigned to control the SFP+ module receiver
rate. It is connected internally to a 30 kW 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 insufficient light
has been detected for proper operation.

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 ∆T output jitter and ∆R 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.

Power supply filtering is recommended for both the transmitter and receiver. Filtering should be placed on the host assembly as close to the Vcc pins as possible for
optimal performance. Vcc,R and Vcc,T should have separate filters.

Eye safety Digital Diagnostic Monitoring and Serial ID Operation
The JSH-85L3Ax1-10 optical transceiver is equipped with a two-wire serial EEPROM that is used to store specific information about the type and identification
of the transceiver as well as real-time digitized information relating to the transceiver’s performance. See the Small Form Factor Committee document number
SFF-8472 Revision 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 which 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 1/256°C from -40 to
+85°C with LSB equal to 1/256°C. Accuracy is ± 3°C over the specified operating
temperature and voltage range.

Reading the data
The information is accessed through the SCL and SDA connector pins of the module.
The SFF-8431 Revision 3.2 specification 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 field (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 defined 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 JSH-85L3Ax1-10 optical transceiver is supplied with a process plug. This plug
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.
Recommended cleaning and degreasing chemicals
JDSU 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, 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 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 Eye Safety
The JSH-85L3Ax1-10 Optical Transceiver is a CLASS 1 LASER PRODUCT as defined by the international standard IEC 60825-1 Second Edition 2007-03 and by
U.S.A. regulations for Class 1 products per CDRH 21 CFR 1040.10 and 1040.11.
Laser emissions from Class 1 laser products are not considered hazardous when
operated according to product specifications. Operating the product with a power
supply voltage exceeding 4.0 volts may compromise the reliability of the product,
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
Drug Administration (21 CFR 1040).
The use of optical instruments with this product will increase eye hazard.
