Product Description:
This product is compliant with the QSFP28 standard (SFF-8636 Rev
2.10a) and the IEEE802.3cu D3.2 100GBASE-FR1 standard. It features
a high speed I/O electrical interface (CAUI-4) and a single 3.3V
supply voltage. The maximum power consumption is 4W and it can
operate in temperatures ranging from 0-70 ºC.
It is equipped with a 1311nm EML laser and PIN receiver, as well as
a hermetically sealed TO based design. The QSFP28 MSA package comes
with a duplex LC connector and a two wire serial interface with
digital diagnostic monitoring. It also boasts KP4 FEC termination
inside the module and supports a 2km reach of single mode fiber.
In addition, this product is compliant with the EU Directive
2011/65/EU (RoHS compliant).
