Brief Introduction
The Vchung 40G QSFP+ Twinax copper direct-attach cables are suitable for very short distances and offer a highly cost-effective way to establish a 40-Gigabit link between QSFP+ ports of QSFP+ switches within racks and across adjacent racks. These cables are used for 40GbE and Infiniband standards, to maximize performance. It is fully compliant with QSFP MSA and IBTA (InfiniBand Trade Association). The QSFP+ cables support the bandwidth transmission requirements as defined by IEEE802.3ba (40 Gb/s) and Infiniband QDR ( 4×10 Gb/s per channel) specifications.

 | 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. |

| 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. |  |
