Absolute Maximum Specifications
Absolute maximum ratings are those beyond which damage to the device may occur.
Prolonged operation between the operational specifications and absolute maximum ratings is not intended and may cause permanent device degradation.

Notes:
-
Average launch power, each lane (min) is informative and not the principal indicator of signal strength.
-
Even if TDECQ < 1.4dB, OMAouter (min) must exceed this value.
-
Transmitter reflectance is defined looking into the transmitter.
-
Receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level.
-
Average receive power, each lane (min) is informative and not the principal indicator of signal strength. A received power below this value cannot be compliant; however, a value above this does not ensure compliance.
-
Receiver sensitivity (OMAouter), each lane (max) is informative and is defined for a transmitter with SECQ of 0.9 dB.
-
Measured with conformance test signal at TP3 for the BER = 2.4x10-4.
-
These test conditions are for measuring stressed receiver sensitivity. They are not characteristics of the receiver.

Connector and Cabling Details
MPO-16/APC Optical Connector
The single-port NDR transceiver has a unique NVIDIA patented design enabling, multiple-push-on/angled-polished-connector 16-fiber (MPO-16/APC) optical connectors per single OSFP form-factor by turning the optical connectors vertically in the twin-port transceiver end. This enables it to host two NDR transceivers inside, each with its own MPO-16/APC optical connector operating independently that can link to another single-port 800Gb/s NDR transceiver.
The MPO-16 has a 16-fiber ribbon where 16-fibers are used – eight transmit and eight receive fibers for the 8-channels 100G-PAM4.
-
The APC design minimizes back reflections and signal interference by diverting back reflected light from the fiber face to be absorbed into the fiber cladding.
-
A positioning key on top of the connector together with the alignment pins define the fiber position numbering scheme to align pin 1 in the optical connector to pin 1 in the transceiver also called “polarity”
-
Transceivers have alignment pins for precise positioning of the cable connector against the optical beams. The fiber cable has alignment holes matching the transceiver’s pins.
-
Important to note that transceivers have pins. Optical connectors have holes used with transceivers have holes. Optical connectors with pins are not compatible with transceivers and used in trunk cabling to connect two fiber cables together.
The MPO-16/APC optical connector is used in both the 100G-PAM4 based single mode and multimode fiber cables.
Single mode optics is denoted by a yellow-colored pull tab and yellow-colored optical fiber. Green plastic shell on the MPO-16/APC connector denotes Angled Polish Connector and is not compatible with Ultra-flat Polished Connectors (UPC) used with slower line rate transceivers.
