BlueOptics TP-Link ISM321A-20 Transceptor SFP Compatible, 1000BASE-BX-D, LC-Simplex, SMF, TX1550nm/RX1310nm, 20 km

The BlueOptics ISM321A-20 compatible SFP transceiver is a high-performance, cost-effective solution designed for Gigabit Ethernet applications. It operates on single-mode fiber (SMF) with a BiDi (Bi-directional) LC-Simplex connector, transmitting at 1550nm and receiving at 1310nm, supporting distances up to 20km. This module is fully MSA compliant and hot-pluggable, ensuring seamless integration with TP-Link ISM321A-20 and other MSA-compliant SFP ports.

Advantages

This transceiver offers reliable, high-speed data transmission with low power consumption and digital diagnostic monitoring (DDM) for real-time performance tracking. Its BiDi technology reduces fiber infrastructure costs by using a single fiber strand for both transmit and receive. The commercial temperature range (0°C to 70°C) makes it suitable for most indoor environments.
