Cisco SFP-25GBX-D-40 Compatible SFP28 25GBASE-D BiDi 1310nm-TX/1270nm-RX 40km DOM Simplex LC/UPC SMF Optical Transceiver Module

The Cisco SFP-25GBX-D-40 is a 25GBASE-D BiDi SFP28 optical transceiver module designed for 40km reach over single-mode fiber (SMF). It operates on 1310nm-TX/1270nm-RX wavelengths, making it a bidirectional (BiDi) transceiver, which means it can transmit and receive data over a single fiber strand. This module is compatible with Cisco devices and supports 25Gbps Ethernet.

Key Features:

• Form Factor: SFP28
• Data Rate: 25Gbps
• Wavelength: 1310nm (TX) / 1270nm (RX)
• Distance: Up to 40km
• Fiber Type: Single-mode fiber (SMF)
• Connector Type: LC/UPC
• DOM Support: Digital Optical Monitoring (DOM) for real-time diagnostics
• BiDi Technology: Transmits and receives on a single fiber strand

Applications:

• Data Center Interconnects (DCI)
• Enterprise Networking
• Telecom Networks
• High-speed 25G Ethernet links

Compatibility:

• Designed for Cisco switches and routers that support SFP28 modules.
• Ensure compatibility with your specific Cisco device by checking the datasheet or compatibility matrix.

Benefits:

• Cost-Effective: BiDi technology reduces fiber infrastructure costs by using a single fiber for both transmit and receive.
• High Performance: Supports high-speed 25Gbps Ethernet for demanding applications.
• Long Reach: Capable of reaching up to 40km, making it suitable for long-haul applications.

Notes:

• Always verify compatibility with your networking equipment before purchasing.
• Third-party compatible modules may be available, but ensure they meet quality and performance standards.

If you’re looking for a compatible or third-party alternative, ensure it meets the same specifications and is tested for reliability and performance.
