Allied Telesis AT-SPBD20DUAL-14 CSFP 2x1G 20km Dual-Channel BiDi Single-Fiber Optical Transceiver Module (1490Tx/1310Rx, LC)

Basic Parameter Table

Core Product Features

1. Allied Telesis dual-channel BiDi compact SFP (CSFP) optical module, integrates two independent 1G BiDi transceivers in one standard SFP slot, doubles port density and greatly saves switch slot resources for high-density access networks.
2. Single-fiber bidirectional design per channel, transmits 1490nm and receives 1310nm on each single-mode fiber, paired with AT-SPBD20DUAL-13 (1310Tx/1490Rx) matching module, greatly saves fiber core resources for FTTH and access network.
3. Standard duplex LC dual single-fiber port, matches universal single-fiber simplex LC patch cords; built-in independent full DDM monitoring per channel to remotely read Tx/Rx optical power, module temperature and supply voltage.
4. Compact CSFP hot-swappable design, plug-and-play without powering down switches, zero firmware incompatibility alarms on Allied Telesis high-density access switching platforms.
5. Commercial temperature design, reliable 24/7 continuous operation for high-density FTTH broadband access, enterprise campus aggregation and data center high-density single-fiber interconnection.
