Brief Introduction
The Vchung QSFP/QSFP+ Passive Electrical Loopback is used for testing QSFP/QSFP+ transceiver ports in board level test. By substituting for a full-featured QSFP/ QSFP+ transceiver, the electrical loopback provides a cost-effective low loss method for QSFP/QSFP+ port testing QSFP/QSFP+ ports. Transmit data from the host is electrically routed, (internal to the loopback module), to the receive data outputs and back to the host. It provides an economical way to exercise QSFP/QSFP+ ports during R&D validation, production testing, and field testing. The loopback module is packaged in a standard MSA housing compatible with all provides an economical way to exercise SFP28 ports during R&D validation, production testing and field testing.

 | 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. |  |
