  • Huawei S6720-LI Series Switch Optical Module Solutions

    The S6720-LI series, a new generation of Huawei's compact all-10G box switches, is designed for use in campus networks and data center 10G access. The S6720-LI series switch includes three models with a switching capacity of 1.28Tbps/12.8Tbps, supporting packet forwarding rates of 240Mbpps and 480Mpps. It is equipped with high-density 10GE and 40GE ports and is typically paired with 10G SFP+ o

  • Huawei SFP-10G-ZR: Long-Range Connectivity Solutions

    If the transmission distance is relatively short, we can consider using Walsun 10G DAC high-speed cables for transmission. The length specifications of DAC in the market can be customized based on actual transmission needs, but generally do not exceed 7 meters. If connecting a 10G port with an SFP+ optical interface to a 10G port with a network interface switch for short-distance connections, Wals

  • 100G CFP/CFP2 DCO Coherent optical module FAQS

    100G CFP/CFP2 DCO Coherent optical module Q&AWhy does the module use DP-QPSK modulation?Dual polarization quadrant-phase shift keying (DP-QPSK) modulation technology based on coherent reception is the first choice for 100G modulation format. On the one hand, DP-QPSK can maximize the spectral efficiency, and on the other hand, it takes advantage of the phase modulation technology to PMD, disper

  • Coherent optical module chip working principle

    As shown in Figure 1, in the coherent optical module, at the transmitter side, the customer then the electrical signal through the digital signal processing function in the DSP chip to complete the specific probability distribution and QAM mapping of the symbols, which includes the probability distribution matching, FEC coding, QAM mapping, and other functions, and then the digital QAM signal of t

  • Differences Between High-Speed Coherent Modules DCO and ACO

    With the rapid development of 5G services, the entire network, from access to the core, must upgrade to higher data rates to meet the demands of the business. However, higher rates also mean higher power consumption. To reduce the operating expenses of operators, making networks more environmentally friendly and energy-efficient, power reduction in optical devices and transceiver modules has becom
