D-Link DEM-330T SFP 1000BASE-BX BiDi Single-Fiber Gigabit Optical Transceiver

Basic Parameter Table

Core Product Features

1. D-Link bidirectional single-fiber gigabit SFP module, only one single-mode fiber core needed for sending & receiving signals, greatly saving fiber resource costs.
2. Must be used in matched pairs: this model TX1550/RX1310 needs to pair with DEM-331T (TX1310/RX1550) to realize full-duplex bidirectional communication.
3. Complies with 1000BASE-BX BiDi standard, stable 10km transmission over standard single-mode fiber, ideal for old network reconstruction with insufficient spare fiber cores.
4. Hot-swappable plug-and-play design, compatible with all D-Link gigabit switches with SFP slots, no need to power off equipment during replacement for easy maintenance.
5. Low power consumption, stable laser output, strong anti-interference performance, supports 24/7 uninterrupted long-term operation for campus, factory and branch point-to-point fiber links.
6. Ultra cost-effective single-fiber BiDi solution, perfect for projects with limited fiber resources.

Typical Application Scenarios

1. Point-to-point interconnection with insufficient single fiber cores: campus cross-building, factory remote workshop monitoring backhaul within 10km single-mode fiber range.
2. Old office network renovation, small branch store gigabit private line access where only one spare single fiber is available.
3. Not applicable for multi-mode fiber; must be matched with opposite wavelength BiDi module for normal communication.
