Product Description
   CWDM-25G-SFP28-40-33 is a 25G SFP28 CWDM 40km 1330nm 25GBASE-ER Lite 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 19 dB, which in most cases is enough to reach 40 km over OS2 fiber with FEC (Forward Error Correction) function, or 30km without FEC. 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 CWDM 40km 1330nm uses top quality DFB (Distributed Feedback Laser) transmitter and 25Gb/s APD receiver. CWDM-25G-SFP28-40-33 25GBASE-ER Lite supports DDM/DOM optical diagnostics that provide real-time diagnostic information about the present operating conditions. CWDM-25G-SFP28-40-33 operates in Standard 0°-70°C temperature range and has Double LC interface. CWDM-25G-SFP28-40-33 1330nm CWDM 25GBASE-ER Lite SFP28 support 24.33-25.78 Gbps data rate and is designed for 25G Ethernet (25.78 Gbps) applications. CWDM-25G-SFP28-40-33 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.
