Functional Characteristics (Optical)
The following tables list the performance specifications for the various functional blocks of the integrated optical
transceiver module.
Note 1: Output power monitor accuracy and output power tuning accuracy are equivalent.
Note 2: Stability is defined as variation over time at a fixed temperature and wavelength.
Note 3: Time to reach 90% of steady-state optical power upon de-assertion of Tx disable.
Note 4: Time to reach output power during blanking upon assertion of Tx disable.
Note 1: ROSNR test conditions as follows (unless stated otherwise):
• Back-to-back, single wavelength present.
• No dispersion
• Rx signal power within the valid range for the transmission mode.
• Tx power provisioned to -12 dBm.
• No PDL other than the Module itself.
• PMD/DGD <= 2ps mean
• <= 5krad/s rate of change of SOP.
• ROSNR is defined to be constant across all frequency channels.
At different wavelength, ROSNR is defined by
OSNR_linear_per_0.1nm (λ) = OSNR_linear_per_12.5GHz) x (λ0 /λ nm)2 ,
where λ0 = sqrt( c/12.5GHz ) = 1548.65735 nm.
Noise bandwidth of 0.1 nm = 12.5 GHz at 1548.65735 nm.
Note 2: No ROSNR Rx power penalty across plug population obtained at greater than or equal to the maximum
of this value. 400ZR ROSNR is valid over the stated Rx Input power range.
Note 3: Error free performance @ OSNR > 35 dB/12.5GHz
Note 1: Rx input operating dynamic range guaranteed across plug population (need more note here?). For 400ZR, this is the input power
range over which the stated ROSNR is supported.
Note 2: Minimum/maximum power during transient contained within the Rx input operating power range for the transmission mode. ROSNR
penalty is referenced versus the steady state ROSNR at the minimum power of the input transient. At 50us 10%-90% maximum slew rate, and
operation within Rx operating input power range.
Note:
There is no appsel code for IEEE 802.3cw 400GBASE-ZR since it has the same symbol rate with 400ZR OIF
OIF 400ZR:
0x01 (100GHz DWDM amplified) is supported
0x03 (75GHz DWDM amplified) is supported
0x02 (single wavelength unamplified) is also supported.
Mechanical Diagram
The QSFP-DD module is designed to be plugged into a host cage assembly with a riding heat sink. The complete
mechanical details are specified by QSFP MSA documents at XX.
Figure 7-1 shows a mechanical drawing of the QSFP-DD module.
Warnings
Handling Precautions: This device is susceptible to damage as a result of electrostatic discharge (ESD). A static
free environment is highly recommended. Follow guidelines according to proper ESD procedures.
Laser Safety: Class 1 Laser Product. Complies with FDA performance standards for laser products except for
conformance with IEC 60825-1 Ed. 3., as described in Laser Notice No. 56, dated May 8, 2019. Radiation emitted
by laser devices can be dangerous to human eyes. Avoid eye exposure to direct or indirect radiation.
