The new connector has a mounted depth of 3.1mm, stands 0.9mm high, and weighs 0.046g. It’s currently available with 31, 35, 41, and 51 positions and meets halogen-free and RoHS requirements.
Samtec’s new NovaRay™ high-bandwidth, high-density interconnect system has a pin-to-ground differential pair configuration that enables very low crosstalk to 40GHz+, tight impedance control, and minimal variance in data rate as stack heights increase. It is 112 PAM4 capable, rated up to 56Gb/s NRZ per channel, and boasts an industry-leading aggregate average data rate of 1.33Tb/s per square inch. Its 92Ω impedance rating addresses both 85Ω and 100Ω applications. NovaRay is initially available in a variety of configurations with 8–72+ pairs due to its modular design. Board-to-board configurations currently include 8 pairs capable of 448Gb/s aggregate, 16 pairs capable of 896 Gb/s aggregate, and 32 pairs capable of 1.8Tb/s aggregate, with stack heights spanning 7–20mm. Right-angle and vertical cable options are in active development.
Molex expanded its zSFP+ interconnect system for 56Gb/s serial channels, which delivers excellent signal integrity with superior EMI protection in 10Gb/s Ethernet and 16Gb/s Fibre Channel applications. The 20-circuit zSFP+ SMT connectors and cage assemblies share the same PCB footprint, mating interface, and EMI cage dimensions as the SFP+ SMT form factor for backwards compatibility and feature a preferential coupling design with a narrow-edge, coupled, blanked-and-formed contact geometry and insert molding designed to optimize electrical performance. Single-port cages in press-fit, solder-post, and PCI (1°) versions provide flexible solutions for various board thicknesses and assembly processes at a comparable cost to SFP+ cages, and 1x ganged EMI cages with new Gen II EMI belly gaskets provide improved EMI shielding compared to SFP+ cages. The press-fit tails accommodate belly-to-belly applications for both single and ganged cages for efficient use of PCB space, and the cages offer optional rear- and side-mounted lightpipe cover assemblies for improved flexibility of PCB signal routing for LEDs. The system also offers customizable LC duplex cable assemblies with optical mode three and four (OM3, OM4) fiber for stable and convenient SFP and SFF device testing and cost-effective Temp-Flex® 28Gb/s cable assemblies for next-generation data rate performance with low insertion loss.

The gold-plated contacts are resistant to shock and vibration, accept 22AWG wire, comply with IPC-A-620 cable harnessing specifications, are rated for up to 1,000 mating cycles, and exhibit a 60% greater contact wipe than existing Datamate contacts.
Samtec’s new Flyover QSFP28 Double-Density (FQSFP-DD) is the first product to take the flyover architecture concept to the QSFP-DD form factor — a next-generation, high-density, high-speed, pluggable, backwards-compatible module. The flyover approach overcomes the limitations of signal loss on a PCB trace, which become ever more relevant as advanced 50Gb/s+ per channel ASIC and FPGA solutions hit the market, and achieves a greater performance margin compared to the QSFP-DD connector to PCB approach. The new FQSFP-DD quadruples the aggregate bandwidth of conventional QSFP modules by adding a second row of contacts to support an eight-lane electrical interface (x8 bidirectional for 16 differential pairs) and offers 28Gb/s NRZ per channel, direct-connect sidebands that increase system airflow and eliminate the need for extra cables, and belly-to-belly mating for maximum density.
Ironwood Electronics’ new GT-BGA-2076 BGA socket enables up to 75GHz with less than 1dB of insertion loss and very low inductance in wide temperature applications (-55°C to +160°C) with performance equivalent to direct-solder versions. It’s designed to dissipate few watts using a compression screw, but can be customized for up to 300W, has a very small footprint that allows capacitors and resistors to be placed close by, and features a swivel lid that allows ICs to be changed out quickly.
Molex’s new NearStack high-speed connector system and cable jumper assemblies use twinax cables to deliver a PCB alternative with superior signal integrity and low insertion loss while enabling 56Gb/s NRZ and a path to 112Gb/s PAM4. They also feature compact, low-profile (9mm) connectors with a 0.6mm pitch for tray and panel space savings. The new system is ideal for use in datacenter and top-of-the-rack telecommunications switches, cell towers, remote radio units, and core routers.
Cambridge Electronic Industries released new surface-mount, right-angle, 12GHz BNC connectors for that enable high precision, low loss, rapid assembly, and volume production in very-high-throughput broadcast and video applications.

Wire and Cable
LEONI announced prototypes of new 400Gb/s copper solutions for QSFP-DD and OSFP cable systems. Based on the company’s slim, efficient, and high-performance ParaLink 25s bulk cable, the new 16-pair solutions combine high signal integrity with low packing density and enable full compatibility both between the two standards and backwards. The QSFP-DD solution features a maximum gauge of 28AWG over a maximum length of 3m, while the OSFP solution features a maximum gauge of 26AWG at a maximum of 4m. As a member of the multi-source agreement (MSA) groups for QSFP-DD and OSFP, LEONI was early to electromagnetically simulate the development of cable systems with its own components and to prove the feasibility of active and passive copper solutions for these standards. Initial prototypes have proven that its OSFP and QSFP-DD cable systems can passively transfer 8 x 25Gb/s at 25GHz (which corresponds to 200Gb/s NRZ) and up to 8 x 50Gb/s actively (which corresponds to 400Gb/s PAM4) without interference. Both cable systems also demonstrated the ability to overcome greater lengths will full signal integrity when transferring 400Gb/s data due to an integrated PAM4 amplifier.
