Features

Only compatible with SOSFP1G-BX20D35

The SO-SFP-1000BASE-BX20D is a bi-directional transceiver solution operating directly on a single-fiber without the need for a separate optical filter. This is achieved by having two transceivers that inject different wavelengths into the same single-fiber. The solution thus consists of two transceivers; SO-SFP-1000BASE-BX20D-35 and SO-SFP-1000BASE-BX20D-53, operating at 1310nm and 1550nm respectively. Using a single-fiber solution provides a cost-efficient solution for interconnect and it simplifies the patching since no separate transmit/receive direction has to be taken into account.

Optimized Single-Fiber Bi-Directional SFP Solution

The SO-SFP-1000BASE-BX20D enables high-speed data transfer over a single-mode fiber using separate transmit and receive wavelengths (1310nm and 1550nm). This design significantly reduces cabling complexity and cost in interconnects. Its plug-and-play nature streamlines installation and operation.

Reliable Long-Distance Optical Connectivity

Supporting both 1G Fiberchannel and 1G Ethernet, the module delivers robust optical performance for distances up to 20km. Enterprises and data centers benefit from secure, high-performance links with easy infrastructure requirements. The 14dB power budget further ensures dependable communication.

Flexible Dual-Temperature Range for Industrial Use

The transceivers are available in two temperature range options, including a full industrial range from -40°C to +85°C. This makes the BX20D an ideal solution for harsh or mission-critical environments. Operational stability is maintained even under extreme temperature swings.

Integrated DDM for Real-Time Monitoring

Digital diagnostic monitoring is built-in via a 2-wire serial interface according to SFF-8472 standards. Users gain real-time visibility over key parameters, enabling proactive maintenance and enhanced network security. This advanced feature is standard for all models.

Cost-Efficient and Hassle-Free Network Integration

The single-fiber approach simplifies patching, minimizing the need for additional components and reducing total costs. All compatibility and diagnostic functionality is included out of the box. BX20D provides a smart and effective solution for modern optical networks.
