Huawei 16 Passive Aggregation Switch

The Huawei 16 Passive Aggregation Switch (HW-PEN-16LC) is a passive optical aggregation module designed for all-optical campus networks, enabling 2:8 optical splitting without requiring power or ELV rooms.OverviewThe Huawei 16 Passive Aggregation Switch is part of the Xingmai Passive Ethernet Network (PEN) solution, which is an all-optical campus network architecture ideal for high-density environments such as education, healthcare, and enterprise campuses . The switch functions as a passive aggregation module, also referred to as a passive optical splitter or multiplexer, and is used to aggregate and distribute optical signals between central switches and remote devices like access switches, RUs, and Wi-Fi APs .Hardware FeaturesModel Options: HW-PEN-16LC-2KM and HW-PEN-16LC-10KM, supporting different optical reach distances .Passive Operation: No mains power supply is required, minimizing fire risks and eliminating the need for ELV rooms .Optical Splitting: Supports 2:8 passive optical splitting, meaning two uplink channels can be split into eight downlink channels for remote devices .Uplink Multiplexing: Aggregates signals from multiple remote modules into a single uplink channel, enabling efficient bidirectional optical communication .Installation: Can be installed in a passive aggregation module subrack, which has three slots and is rack-mountable. Each slot can host one HW-PEN-16LC module .Operational PrinciplesDownlink Direction: The module splits optical signals from the uplink proportionally, without altering wavelengths. Each TX port carries all eight channels from the central optical module .Uplink Direction: Multiplexes signals from remote optical modules into a single uplink channel, ensuring efficient aggregation .Flexibility: The passive design allows flexible deployment in locations where power availability is limited or where minimizing infrastructure complexity is desired .Integration with Huawei NetworksWhile the passive aggregation module itself does not require configuration, it is typically deployed alongside Huawei PEN central switches and remote devices. For scenarios requiring link aggregation at Layer 2 or Layer 3, Huawei switches support Eth-Trunk configurations and LACP for redundancy and bandwidth optimization . This ensures that the network can scale efficiently while maintaining high reliability.Use CasesCampus Networks: Ideal for connecting multiple buildings or floors without extensive active equipment.High-Density Deployments: Suitable for environments with many access points or devices, such as schools, hospitals, and large offices.Energy-Efficient Installations: Passive design reduces power consumption and operational costs. In summary, the Huawei 16 Passive Aggregation Switch is a key component of the PEN solution, providing passive optical aggregation, flexible installation, and reliable signal distribution for modern campus networks without the need for active power or complex infrastructure.
