less popular in QSFP to CX4 the data center

At a distance of about 100m range, the only only QSFP to CX4 can use multimode fiber supports SR, or within the 10km using duplex single-mode fiber optic QSFP switches support SR–is using the same port. ColorChip and other companies such as Sumitomo QSFP module; Oclaro (by Opnext mergers and acquisitions) QSFP (also known as Quad Small Form-Factor Pluggable) copper cable assemblies are a high-performance computing connectivity solutions supporting InfiniBand QDR, DDR,SDR, CX4, Fibre Channel and SAS applications.QSFP+ to CX4 Active Optical cables feature a QSFP+ Zinc Die Cast SFF-8436 connector on one end, and an External CX4 SFF-8470 with a pull latch connector on the other end. This cable is built using Optical Fiber for Active ports.SFPDA is similar in concept QSFP to CX4 but provides a bit more flexibility. Normally, you may have a switch or NIC that is designed to be able to support the addition of SFP based optics modules for a 10GbE fiber connection.There are also what referred to as ‘active optical' cables are for QSFP to CX4, which actually have an optics module in the termination of the cable,QSFP to CX4 connectors provide four channels of data in one pluggable interface. Each channel is capable of transferring data at 10Gb/s and supports a total of 40Gb/s as specified for QSFP+.
