Specifications

       Product Overview:
  • The Cisco Compatible SFP-25BL32-40C 25G BiDi Optical Transceiver by Ascent Optics is a high-speed, long-range optical module designed for 25Gbps Ethernet over single-mode fiber (SMF) using Wavelength Division Multiplexing (WDM). It features 1330nm TX / 1270nm RX wavelengths, enabling bi-directional data transmission over a single fiber strand up to 40km, ideal for dense and extended network infrastructures.
  • This hot-swappable SFP28 BiDi module is equipped with an LC simplex connector, supports Digital Optical Monitoring (DOM), and operates efficiently in environments ranging from 0°C to 70°C, making it suitable for enterprise networks, metro aggregation layers, and 5G transport links across Singapore.
       Features:
  • 25Gbps High-Speed Data Rate – Optimized for modern data center and carrier-class networks
  • 1330nm Transmit / 1270nm Receive – WDM technology for single-fiber efficiency
  • Up to 40km Reach – Ideal for long-distance single-mode fiber deployments
  • Simplex LC Connector – Reduces fiber usage and cost
  • Digital Diagnostics Monitoring (DOM) – Monitors real-time module performance
