  • Huawei Optical Module Common Models

    Optical modules are important devices in fiber optic communication systems. Huawei Optical Module is manufactured by Huawei Technologies Co. and originated in Shenzhen. Huawei Technologies Co., Ltd. is a telecommunications network solutions provider. Huawei's main business scope is switching, transmission, wireless and data communication telecommunication products, providing network equipment,

  • What is the range of QSFP DD?

    The range of QSFP DD (Quad Small Form-factor Pluggable Double Density) transceivers is typically up to 100 meters when using multimode fiber, and up to 10 kilometers when using single-mode fiber.Why QSFP-DD over other 400G capable form factors (OSFP, CFP8, & COBO)?When compared to the octal small form pluggable (OSFP), the QSFP-DD is quite similar. Both utilize eight lanes to achieve 400G data

  • What is the QSFP DD format?

    The QSFP-DD (Quad Small Form-factor Pluggable Double Density) format is a high-speed, quad small form factor pluggable optical transceiver module format. It is an evolution of the original QSFP format, with a doubled port density and increased data throughput. QSFP-DD modules can support data rates of up to 400Gbps.Why QSFP-DD over other 400G capable form factors (OSFP, CFP8, & COBO)?When comp

  • What size is a QSFP DD module?

    A QSFP DD (Quad Small Form-factor Pluggable Double Density) module measures 18.35mm in width, 8.5mm in height, and 92.4mm in length.Why QSFP-DD over other 400G capable form factors (OSFP, CFP8, & COBO)?When compared to the octal small form pluggable (OSFP), the QSFP-DD is quite similar. Both utilize eight lanes to achieve 400G data rates (8x50G), however, the OSFP is planned to later support 8

  • What is the difference between CWDM and DWDM?

    Wavelength division multiplexing (WDM) includes coarse wavelength division multiplexing (CWDM) and dense wavelength division multiplexing (DWDM). It refers to the simultaneous transmission of multiple signals of different wavelengths over a single fiber. The main purpose WDM is to increase the available bandwidth of the fiber and to expand capacity without laying additional fiber optic cables. The
