The part number **10MK-B0-R** typically refers to a **10 Gigabit Ethernet (10GbE) SFP+ Optical Transceiver module**, often associated with networking hardware manufacturers or third-party compatible suppliers (such as those used in server/storage environments like Dell, HP, or specialized industrial equipment). Below is a breakdown of the technical specifications and characteristics of this electronic component. --- ### 1. Technical Specifications This module is designed for high-speed data transmission over fiber optic cabling. | Feature | Specification | | :--- | :--- | | **Form Factor** | SFP+ (Small Form-factor Pluggable Plus) | | **Data Rate** | 10.3 Gbps (10 Gigabit Ethernet) | | **Media Type** | Multi-Mode Fiber (MMF) | | **Connector Type** | Dual LC Connector | | **Wavelength** | 850 nm | | **Max Distance** | Up to 300 meters (on OM3 fiber) | | **Operating Voltage** | 3.3V | | **Compliances** | RoHS, IEEE 802.3ae, SFF-8431 | --- ### 2. Key Internal Components The "Electronic Parts" within this module consist of several high-precision sub-assemblies: * **TOSA (Transmitter Optical Sub-Assembly):** Contains a **VCSEL (Vertical-Cavity Surface-Emitting Laser)** which converts electrical signals into light pulses at 850nm. * **ROSA (Receiver Optical Sub-Assembly):** Contains a **PIN Photodiode** and a **TIA (Transimpedance Amplifier)** to convert incoming light back into electrical signals. * **Laser Driver:** An integrated circuit (IC) that controls the laser's modulation and bias current. * **Limiting Amplifier:** Restores the electrical signal from the ROSA to logic-level swings for the host system. * **EEPROM:** A memory chip that stores identification data (vendor name, serial number, part number) so the switch/router can recognize the module. * **DDM/DOM Hardware:** Digital Diagnostic Monitoring circuitry that tracks real-time parameters like temperature, voltage, and optical power. --- ### 3. Part Number Suffix Meaning In many electronic component naming conventions: * **10M:** Usually indicates the 10 Gigabit speed or Multi-mode capability. * **-R:** Generally stands for **RoHS Compliant** (Restriction of Hazardous Substances), indicating the part is lead-free and environmentally friendly. ### 4. Application Use Cases * **Data Centers:** Connecting servers to top-of-rack switches. * **Enterprise Networking:** High-speed uplinks between floors or buildings within 300 meters. * **Storage Area Networks (SAN):** Used in high-speed storage arrays. ---
