Cables and Transceivers

LinkX Direct Attach Copper cables are the lowest cost, 25G-to-400GbE high-speed links for inside racks up to 5-meters for 25G-NRZ and 3-meters for 50G PAM4-based cables. DACs offer zero latency delays and power consumption ideal for switch-to-CPU, GPU, and storage subsystems. LinkX designs and manufactures its cables and are extensively tested.

LinkX AOCs are the lowest cost optical interconnect. Fibers are bonded inside connectors act similar to DACs but up to 100 meters. Available at  25G-to-400G data rates. NVIDIA Networking LinkX has the longest history in the marketplace building AOCs and are widely used in HPCs, hyperscale and enterprise networking and in DGX artificial intelligence systems.  Designed and manufactured by LinkX – including several LinkX-designed Integrated circuits.

LinkX transceivers are designed and manufactured by LinkX -including designing many of the transceiver IC components inside. Offering multi- and single-mode transceivers from 1G-to-400G up to 40km reaches in both NRZ and 50G-PAM4 modulation. The same transceivers are used in our AOCs and splitters.

The QSA is a QSFP-to-SFP port Adapter that enables a single-channel Ethernet SFP device to be inserted into a QSFP port. Available in 10G, 25G NRZ versions and 50G-PAM4 they support a wide array of devices 0.5m DACs to AOCs to 10km SFP56 LR transceivers. Very low-cost and consumes zero power and latency and supports 1GBASE-T up to 50G 10km transceivers. Also, available in Extended Temperature Ranges of -10C up to 85C for hot server applications.

LinkX Direct Attach Copper cables are the lowest cost, EDR and HDR links up to 5m for 25G-NRZ EDR and up to 2.5m for 50G PAM4 HDR. DACs offer near-zero latency delays and power consumption making them ideal for in-rack switch to CPU, GPU, memories and storage subsystems. Typically used within system racks linking top-of-rack switches to ConnectX HCAs.

LinkX AOCs Cables are the lowest cost optical interconnect available. Fibers are bonded inside the connectors to act similar to DACs but up to 150 meters for HDR.  Offered in QSFP for  EDR and HDR rates. LinkX has the longest history in the marketplace building AOCs and are widely used in HPCs, hyperscale and enterprises and in DGX artificial intelligence systems.

LinkX optical transceivers are designed and manufactured by LinkX -including designing many  transceiver ICs inside. Offering both multi- and single-mode transceivers in QSFP28 and QSFP56 and from FDR10/FDR, EDR and HDR and up to 2km, 10km and 40km in both NRZ and 50G-PAM4.
