Description
155Mbps SFP Bi-Directional Transceiver | 20KM Reach Tx1310nm/Rx1490nm | (TK-B3403-3LCD20)
The SFP-BIDI transceivers are high-performance, cost-effective modules supporting data rates of 155Mbps with 20KM transmission distance over single-mode fiber.
The transceiver consists of three main sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA), and an MCU control unit. All modules satisfy Class I laser safety requirements and are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472 specifications.
Applications
  • SDH STM-1, S-1.1, L-1.1, L-1.2
  • SONET OC-3 IR1, LR1, LR2
