The QSFPTEK QT-SFP-10G-T is a high-performance integrated duplex data link module designed for bi-directional communication over copper cable. It is specifically engineered for high-speed communication links requiring 10 Gigabit Ethernet over Cat 6a/7 cabling. This module is the first SFP+ transceiver to offer 10Gb/s communication over this type of media.
Features
- Supports links up to 30m using Cat 6a/7 cable.
- SFF-8431 and SFF-8432 MSA compliant.
- IEEE 802.3az compliant.
- Low power consumption (2.5W max @ 30m).
- Fast Retrain EMI Cancellation Algorithm.
- Low EMI emissions.
- I2C 2-wire serial interface for Serial ID and PHY registers.
- Auto-negotiates with other 10GBase-T-NC PHYs.
- Automatic detection and correction of wiring and polarity swaps.
- Robust die-cast housing with a bail latch style ejector mechanism.
- Supports both unshielded and shielded cables.
General Specifications
The module operates within the following parameters:
- Bit Error Rate (BER): 10^-12
- Operating Temperature: -5°C to 85°C (Case temperature)
- Storage Temperature: -40°C to 85°C (Ambient temperature)
- Operating Humidity: 5% to 95% (Non-condensing)
- Power Consumption: 2.3W to 2.5W @ 30m
- Input Voltage: 3.0V to 3.6V
Pin Assignment
The module features a 20-pin interface. Key pins include:
- Pins 1, 10, 11, 14, 17, 20: Transmitter/Receiver ground.
- Pin 2: Transmitter Fault.
- Pin 3: Transmitter Disable (Laser output disable on high or open).
- Pin 4: SDA (Data line for serial ID).
- Pin 5: SCL (Clock line for serial ID).
- Pin 6: Module Absent (Grounded within the module).
- Pin 8: Loss of Signal (LOS) indication.
- Pins 12, 13: Receiver Data (Inverted/Non-inverted).
- Pins 18, 19: Transmitter Data (Non-inverted/Inverted).
- Pins 15, 16: Receiver/Transmitter power supply.
Electrical Pad Layout
The electrical pad layout defines the physical connection points for the module when inserted into the host device. Ensure proper orientation toward the host and bezel as indicated in the technical diagrams.
Mechanical Specifications
The module is constructed with a zinc die-cast housing with nickel plating. It utilizes a bail latch ejector mechanism for easy removal from the cage. Refer to the mechanical dimensions diagram for precise physical measurements.
