D-Link DEM-302S-BXU SFP 1000BASE-BX BiDi Short-Distance Single-Fiber Gigabit Optical Transceiver

Basic Parameter Table

Core Product Features

1. Entry-level D-Link short-distance bidirectional single-fiber gigabit SFP module, only one single-mode fiber core realizes transmit & receive, halves fiber core consumption.
2. Pairing rule: This TX1310/RX1550 module must be matched with DEM-302S-BXD (TX1550/RX1310) to implement full-duplex bidirectional communication.
3. Complies with 1000BASE-BX WDM BiDi standard, stable 2km transmission over standard single-mode fiber, suitable for indoor short-range point-to-point links.
4. Hot-swappable plug-and-play design, compatible with all D-Link gigabit SFP switches; equipment power-off is unnecessary during replacement for easy maintenance.
5. Ultra-low power consumption, stable laser output, strong anti-electromagnetic interference performance, supports 24/7 continuous long-term operation for building internal monitoring and office networking.
6. Ultra-low cost single-fiber BiDi solution, ideal for short-distance network renovation projects with limited spare single-mode fiber cores.

Typical Application Scenarios

1. Short-distance point-to-point interconnection within 2km single-mode fiber: inter-floor office building, small campus internal monitoring backhaul, short-range equipment uplink of factory workshops.
2. Gigabit private line access for small stores and branch offices when only one spare single fiber is available.
3. Not applicable to multi-mode fiber; must be matched with BiDi module of opposite wavelength to communicate normally.
