25G-SFP28-10 is a 25GBASE-LR Multi-Vendor MSA Compatible SFP28 (Small Form-Factor Pluggable 28) Transceiver, operating over Double Fiber Single-Mode Fiber (SMF) optical cable. It has minimum guaranteed optical budget of 8.3 dB, which in most cases is enough to reach 10 km over OS2 fiber. However, distance is just indicative parameter for comfort of identification that is calculated by taking into account minimal optical budget and average attenuation of optical cabling in industry. 25G-SFP28-10 uses top quality DFB (Distributed Feedback Laser) transmitter and 25Gb/s PIN photodiode receiver. 25G-SFP28-10 25GBASE-LR supports DDM/DOM optical diagnostics that provide real-time diagnostic information about the present operating conditions. 25G-SFP28-10 operates in Standard 0°-70°C temperature range and has Double LC interface. 25G-SFP28-10 25GBASE-LR SFP28 support 8.5-28.1 Gbps data rate and is designed for 25G Ethernet (25.78 Gbps) and 10G Ethernet (10.31 Gbps) applications. 25G-SFP28-10 SFP28 Double Fiber optical transceiver is multi-purpose module used in number of different places of today’s networking. Consequently, most popular use cases are in Internet Service Provider (ISP) Access and Metro Networks Data Center Core Networks and Enterprise Campus Networks.
