High Quality and Cost Effective 20km Reach Tx1490nm/Rx1310nm (TK-B4324-3SCD20)
Product Overview
The SFP-BIDI transceivers are high-performance, cost-effective modules supporting dual data-rates of 2.488Gbps/2.125Gbps with 20KM transmission distance over single-mode fiber.
The transceiver consists of three main sections: a DFB laser transmitter, an APD photodiode integrated with a trans-impedance preamplifier (TIA), and an MCU control unit. All modules satisfy Class I laser safety requirements and are compliant with SFP Multi-Source Agreement (MSA) and SFF-8472 standards.
Applications
Gigabit Ethernet
Fiber Channel
Switch to Switch interface
Switched backplane applications
Router/Server interface
Other optical transmission systems
