H3C QSFP-50G-LR-SM1311 50Gbps Optical Connectivity
The QSFP-50G-LR-SM1311 provides high-bandwidth connectivity for network environments where a 50Gbps link is required over single-mode fiber. Its long-reach optical design supports connections of up to 10km, making it suitable for extended network links and data center infrastructure.
The module's 1311nm optical wavelength and single-mode fiber design are intended for long-distance transmission where multimode fiber-based short-reach solutions are not appropriate.
10km Single-Mode Fiber Transmission
The transceiver supports up to 10km transmission over 9/125µm single-mode fiber. Actual link performance depends on the installed fiber, connector condition, optical loss, and the optical characteristics of the connected equipment.
1311nm Optical Wavelength
The QSFP-50G-LR-SM1311 operates at a nominal 1311nm wavelength, providing the optical characteristics required for the specified 10km single-mode fiber link.
Dual LC Optical Interface
The module uses a dual LC optical interface for the fiber connection. The two optical paths provide separate transmit and receive channels for full-duplex communication.
QSFP28 Form Factor
The QSFP28 form factor provides a compact optical interface for compatible H3C networking equipment. Before installation, verify that the target device supports the QSFP-50G-LR-SM1311 and its required 50Gbps operating mode.
