Descripción de producto

TK-B3424-3LCD20 1.25Gbps SFP Bi-Directional Transceiver, 20KM Reach Tx1310nm/Rx1490nm
Product Overview

The SFP-BIDI transceivers are high-performance, cost-effective modules supporting dual data-rate of 1.25Gbps/1.0625Gbps and 20KM transmission distance with single-mode fiber.

The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.

The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472 specifications.

Applications
  • Gigabit Ethernet
  • Fiber Channel
  • Switch to Switch interface
  • Switched backplane applications
  • Router/Server interface
  • Other optical transmission systems
Key Features
  • Dual data-rate of 1.25Gbps/1.063Gbps operation
  • 1310nm FP laser and PIN photodetector for 20KM transmission
  • Compliant with SFP MSA and SFF-8472 with simplex LC receptacle
  • Digital Diagnostic Monitoring with Internal or External Calibration
  • Compatible with SONET OC-24-LR-1
  • RoHS compliant
  • +3.3V single power supply
  • Operating case temperature range: 0°C to +70°C (Commercial) / -40°C to +85°C (Industrial)
Technical Specifications
TK-B3424-3LCD20 1.25Gbps SFP Bi-Directional Transceiver, 20KM Reach Tx1310nm/Rx1490nm 0

Notes:

  • Connected directly to TX data input pins. AC coupled thereafter.
