D-Link DEM-302S-BXD 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 for transmit & receive signals, cuts fiber core usage in half.
2. Pairing requirement: This TX1550/RX1310 module must work with DEM-302S-BXA (TX1310/RX1550) to achieve full-duplex bidirectional communication.
3. Complies with 1000BASE-BX WDM BiDi standard, stable 2km transmission over standard single-mode fiber, ideal for short-distance indoor point-to-point links.
4. Hot-swappable plug-and-play design, compatible with all D-Link gigabit SFP switches; no switch power-off needed during replacement for easy maintenance.
5. Ultra-low power consumption, stable laser output, strong anti-electromagnetic interference, supports 24/7 continuous operation for building internal monitoring and office networking.
6. Low-cost single-fiber BiDi solution, perfect for short-distance projects with limited spare single-mode fiber cores.

Typical Application Scenarios

1. Short-distance point-to-point interconnection within 2km single-mode fiber: office building inter-floor, small campus internal monitoring backhaul, factory workshop short-range equipment uplink.
2. Small store, branch office gigabit private line access where only one spare single fiber is available.
3. Not compatible with multi-mode fiber; must be matched with opposite wavelength BiDi module for normal communication.
