The part number **80-0206-R** is typically associated with high-performance networking components, specifically within the ecosystem of **Cisco Systems** or similar enterprise-grade hardware vendors. It most frequently identifies a specific revision or spare part for a **SFP+ (Small Form-Factor Pluggable Plus)** transceiver or a high-speed **Direct Attach Cable (DAC)**. Below is a detailed breakdown of the electronic specifications and characteristics associated with this part. --- ## 1. General Identification | Feature | Description | | :--- | :--- | | **Common Application** | 10 Gigabit Ethernet (10GbE) | | **Component Type** | Passive Copper Cable or Transceiver Module | | **Standard** | SFF-8431, SFF-8432 | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ## 2. Technical Specifications The "80-0206-R" specifically refers to a **10GBASE-CU SFP+ Cable Assembly**. These are used for short-range high-speed data transfers between switches, routers, and servers. ### Electrical Characteristics * **Data Rate:** Supports multi-gigabit data rates up to 10.5Gbps (backward compatible to 1Gbps). * **Impedance:** 100 Ohm differential. * **Power Consumption:** Extremely low (typically less than 0.1W) as it is a passive copper component. * **Voltage:** 3.3V (provided by the host SFP+ slot). ### Physical Construction * **Connector Type:** SFP+ to SFP+ connectors. * **Cable Type:** Twinaxial (Twinax) shielded cable. * **Wire Gauge:** Usually 30AWG or 24AWG depending on length. * **Length:** Commonly represents a 1-meter to 5-meter variant. --- ## 3. Key Electronic Features * **EEPROM I2C Interface:** Includes an integrated serial ID memory accessible via a 2-wire interface. This allows the host device (like a Cisco Nexus switch) to identify the cable's manufacturer, length, and part number. * **EMI Shielding:** The metal housing of the SFP+ ends is designed for superior Electromagnetic Interference (EMI) suppression. * **Hot-Swappable:** Designed to be plugged in or removed without powering down the host system. --- ## 4. Usage Context In a data center environment, the **80-0206-R** is used for: 1. **Top-of-Rack (ToR) Switching:** Connecting servers to the switch located at the top of the same rack. 2. **Stacking:** Linking two compatible switches to act as a single logical unit. 3. **Storage Area Networks (SAN):** Connecting high-speed storage arrays to the network fabric.
