DATASHEET
DESCRIPTION:
PeakOptical’s PQSFP-2321SF is a transceiver module designed for 10 km optical communication applications.
The design is compliant to 40GBASE-LR4 of the IEEE P802.3ba standard. The module converts 4 inputs channels
(ch) of 10Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb/s
optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 40Gb/s input into 4
CWDM channels signals, and converts them to 4 channel output electrical data.
The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm as members of the
CWDM wavelength grid defined in ITU-T G694.2. It contains a duplex LC connector for the optical interface and
a 38-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, singlemode fiber (SMF) has to be applied in this module.
The product is designed with form factor, optical/electrical connection and digital diagnostic interface according
to the QSFP Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating
conditions including temperature, humidity and EMI interference.
The module operates from a single +3.3V power supply and LVCMOS/LVTTL global control signals such as
Module Present, Reset, Interrupt and Low Power Mode are available with the modules. A 2-wire serial interface
is available to send and receive more complex control signals and to obtain digital diagnostic information.
Individual channels can be addressed and unused channels can be shut down for maximum design flexibility.
The PQSFP-2321SF is designed with form factor, optical/electrical connection and digital diagnostic interface
according to the QSFP Multi-Source Agreement (MSA). It has been designed to meet the harshest external
operating conditions including temperature, humidity and EMI interference. The module offers very high
functionality and feature integration, accessible via a two-wire serial interface.

Diagnostic Monitoring Interface
Digital diagnostics monitoring function is available on all QSFP+ LR4. A 2-wire serial interface provides user to contact with module. The
structure of the memory is shown in flowing. The memory space is arranged into a lower, single page, address space of 128 bytes and
multiple upper address space pages. This structure permits timely access to addresses in the lower page, such as Interrupt Flags and
Monitors. Less time critical time entries, such as serial ID information and threshold settings, are available with the Page Select
function. The interface address used is A0xh and is mainly used for time critical data like interrupt handling in order to enable a onetime-read for all data related to an interrupt situation. After an interrupt, IntL has been asserted, the host can read out the flag field to
determine the affected channel and type of flag.

Time from power on1, hot plug or rising edge of Reset until

A Reset is generated by a low level longer than the
minimum reset pulse time present on the ResetL pin.
Time from power on1 until module responds to data
transmission over the 2-wire serial bus
Time from power on1 to data not ready, bit 0 of Byte 2,
deasserted and IntL asserted
Time from rising edge on the ResetL pin until the module is
fully functional2
Time from assertion of LPMode (Vin:LPMode =Vih) until
module power consumption enters lower Power Level
Time from occurrence of condition triggering IntL until
Vout:IntL = Vol
toff_IntL 500 μs Time from clear on read3 operation of
associated flag until Vout:IntL = Voh. This includes deassert
times for Rx LOS, Tx Fault and other flag bits.
Time from Rx LOS state to Rx LOS bit set and IntL asserted
Time from occurrence of condition triggering flag to
associated flag bit set and IntL asserted

inhibited
Time from mask bit cleared4 until associated IntlL operation
resumes
Time from assertion of ModSelL until module responds to
data transmission over the 2-wire serial bus
Time from deassertion of ModSelL until the module does not
respond to data transmission over the 2-wire serial bus
Time from P_Down bit set 4 until module power
consumption enters lower Power Level
Time from P_Down bit cleared4 until the module is fully
functional3
Note:
1. Power on is defined as the instant when supply voltages reach and remain at or above the minimum specified value.
2. Fully functional is defined as IntL asserted due to data not ready bit, bit 0 byte 2 de-asserted.
3. Measured from falling clock edge after stop bit of read transaction.
4. Measured from falling clock edge after stop bit of write transaction.

Notes:
1. GND is the symbol for single and supply(power) common for QSFP modules, All are common within the QSFP module and
all module voltages are referenced to this potential otherwise noted. Connect these directly to the host board signal
common ground plane. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.
2. VccRx, Vcc1 and VccTx are the receiver and transmitter power suppliers and shall be applied concurrently. Recommended
host board power supply filtering is shown below. VccRx, Vcc1 and VccTx may be internally connected within the QSFP
transceiver module in any combination. The connector pins are each rated for maximum current of 500mA.
