Table of contents
Product Overview
The QSFPTEK QT-SFP-10G-T is a high-performance copper transceiver module designed for high-speed 10 Gigabit Ethernet communication. It provides a reliable duplex data link for bi-directional communication over copper cabling. This module is specifically engineered to support 10Gb/s data rates over Cat 6a or Cat 7 twisted-pair cables, reaching distances of up to 30 meters. It is the first SFP+ transceiver of its kind to enable 10Gb/s performance over this specific media type.
Key Features and Performance
This transceiver is built with a robust die-cast housing and features a bail latch style ejector mechanism for easy insertion and removal from SFP+ ports. It is fully compliant with SFF-8431 and SFF-8432 MSA standards, as well as IEEE 802.3az for energy efficiency. The module incorporates a fast retrain EMI cancellation algorithm to ensure signal integrity and low EMI emissions. It also supports auto-negotiation with other 10GBase-T-NC PHYs and includes automatic detection and correction for wiring and polarity swaps, making it highly versatile in various network environments.
Technical Specifications and Operation
The module operates within a case temperature range of 0°C to 70°C and requires an input voltage of 3.3V. It is designed for low power consumption, peaking at a maximum of 2.5W at 30 meters. The device utilizes an I2C 2-wire serial interface for serial ID and PHY register access. Users should ensure that the host equipment supports the SFP+ interface and that the cabling used meets the Cat 6a/7 specifications to maintain the 30-meter reach. The electrical pad layout follows standard SFP+ pin assignments, including dedicated pins for transmitter and receiver ground, data lines, and fault indication.
Installation and Maintenance
Installation involves inserting the module into a compatible SFP+ cage until the bail latch clicks into place. The module is hot-swappable, allowing for installation without powering down the host device. Maintenance is minimal due to the robust design, but users should ensure that the RJ-45 connector and the SFP+ gold contacts remain clean and free of debris. If communication issues arise, verify the cable category and length, and check the host device logs for any fault indications related to the specific SFP+ port.
