400G SR4 transceivers are optical modules designed to support 400 gigabits per second (Gbps) data rates over short distances. The “SR” stands for “Short Reach,” and the “4” denotes that the transceiver uses four optical channels, each capable of transmitting 100 Gbps. First, let's clarify what VR, SR, DR, FR, LR, ER, and ZR stand for, so that we can understand and identify them: VR (Very Short Range): Transmission distance usually 0~100 meters, using multimode fiber for short data center connections. This transceiver supports 400G transmission over multimode fiber (MMF). Quick summary: SR4 modules are short-reach, multimode solutions that use MPO/MTP ribbon connections and are optimized for cost-effective, dense data-center fabrics over OM3/OM4 MMF; DR4 modules are data-center reach, single-mode solutions (or single-mode MPO variants) that extend reach.

A duplex LC connector is a fiber optic connector that links two optical fibers together in one unit. The optical fiber connector is a kind of detachable passive optical component used in the connection between fiber to fiber, the light source to the fiber, and fiber to the detector to achieve the light maximize coupling to the receiving fiber. The connector integrates two LC (Lucent Connector) interfaces in a single compact housing, allowing one fiber to transmit optical.
