Brief Introduction
The Vchung 400G QSFP112 VR4 is a Four-Channel, Pluggable, Parallel for 400GigabitEthernet Applications. This transceiver is a high performance module for short-range multi-lanedatacommunication and interconnection applications. It integrates Four data lanes in each direction with 4×53.125GBd. Each lane can operate at 106.25Gbps up to 30 m using OM3 fiber or 50 musingOM4 fiber with FEC. These modules are designed to operate over multimode fiber systems usinganominalwavelength of 850nm. The optical interface uses 12 fiber MTP (MPO) connector. TheCommon Management Interface Specification (CMIS) for QSFP112 modules.

 | 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. |
