Brief Introduction
The Vchung 400G QSFP112 DAC is a series of passive DAC (Direct Attach Copper) cable assemblies as a high-speed, cost-effective alternative to fiber optics in the server racks of 400G data center. The 400G QSFP112 DAC contains 8 high-speed copper pairs to support 4 signal channels with a data rate of up to 112Gb/s per channel, providing power-efficient connectivity for 400G short-distance interconnects up to 2 meters.400G QSFP112 DAC cables enable higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers.

Optical transceivers port(LC) For LC port, there are two types of single-fiber bidirectional optical transceivers (one LC connector) and dual-fiber unidirectional optical transceiver (two LC connectors). Single fiber bidirectional is used to send and receive signals in one fiber, and dual fiber unidirectional optical transceivers are used to one fiber to send signals and other fiber to receive signals. |
Optical transceivers series Vchung offer comprehensive optical modules, data rate from 155M to 100G,form factor including SFP,SFP+,XFP,SFP28,QSFP+,CFP,CFP2 and QSFP28,support MMF and SMF interface. Vchung closely follow optical communication market trend, offers comprehensive transceivers solution, including: 1. Data center:100G QSFP28, 40GQSFP+, 10G SFP+, 10G/25G/40G/100G AOC. 2. Transport (OTN,PTN):100G CFP/CFP2/CFP4, 10G SFP+/XFP BIDI/CWDM/DWDM/Tunable, SFP. 3. Wireless(5G fronthaul,middlehaul and backhaul):25G SFP28, 50G QSFP28 PAM4. |
Compatibility The optical transceivers can be adapted to Cisco, Huawei, Huasan, Alcatel-Lucent, Juniper, Brocade, HPE, Extreme, Ericsson and other equipment. It is 100% compatible with all vendors on the market. Of course, before confirming the purchase, it is best to inform model of the equipment to which the optical transceivers is applied. |
Industrial Standards VCHUNG all optical transceivers meet or exceed industrial standards, such as CE and RoHS as well as the regulations of the FCC. Through continuous monitoring before, during and after the production process. |
Full MSA Compliance High availability optical transceivers meet the Multi Source Agreement (MSA) standard SFF-8431. With MSA Standards various manufacturers determine standardizations of the Transceiver to ensure the interoperability. The optical transceivers interface is defined electrically, mechanically and functionally. |
Quality assurance VCHUNG provides OEM services, VCHUNG supply all optical modules are high quality and reliable optical transceivers. For quality assurance, we provide three years replacement and lifelong maintenance service. |
