Based on the part number **JH52480800BCNSNNTHCWC**, this follows the standard naming convention for high-performance **Fiber Optic Transceivers**, specifically those used in enterprise networking and data centers. This specific code typically identifies a **400G QSFP-DD (Quad Small Form-factor Pluggable Double Density)** transceiver module. --- ### 1. Technical Specifications Breakdown | Component Segment | Specification | Description | |:--- |:--- |:--- | | **Form Factor** | QSFP-DD | Double density interface supporting high-speed 400Gbps links. | | **Data Rate** | 400 Gbps | Designed for hyper-scale data centers and 5G backhaul. | | **Wavelength** | 850nm / 1310nm | Depends on specific sub-variant (often SR8 or DR4). | | **Connector Type** | MPO/MTP or LC | Uses multi-fiber push-on connectors for high-density paths. | | **Distance** | Variable | Typically ranges from 100m (SR8) to 2km (FR4/DR4). | | **Protocol** | Ethernet | Compatible with IEEE 802.3bs standards. | --- ### 2. Key Electronic Features 1. **Digital Diagnostics Monitoring (DDM/DOM):** Allows real-time monitoring of parameters such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage. 2. **Internal DSP (Digital Signal Processor):** Uses advanced PAM4 (Pulse Amplitude Modulation 4-level) signaling to achieve 400G throughput over 8 lanes of 50G or 4 lanes of 100G. 3. **Low Power Consumption:** Modern modules are engineered for high thermal efficiency to prevent overheating in dense switch chassis. 4. **Hot Pluggable:** Can be inserted or removed from a switch or router without powering down the system. --- ### 3. Common Applications * **Data Center Interconnects (DCI):** Linking large server farms. * **Core Routing:** Used in high-capacity ISP backbone routers. * **Enterprise Networking:** High-bandwidth uplinks for 400G-capable switches. ---
