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

Basic Parameter Table

Core Product Features

1.  D-Link bidirectional single-fiber gigabit SFP optical module, only one single-mode fiber core for transmit & receive, saves fiber core resources.
2. Matching rule: This model TX1310/RX1550 must pair with DEM-330T (TX1550/RX1310) 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 SFP switches, no power-off required during replacement for easy maintenance.
5. Low power consumption, stable laser output, strong anti-electromagnetic interference, supports 24/7 uninterrupted operation for campus, factory and branch point-to-point fiber links.
6. Ultra low-cost single-fiber BiDi solution, effectively reduces fiber laying cost for renovation projects.

Typical Application Scenarios

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