Description

Product Description
    CWDM-25G-SFP28-40-27 is a 25G SFP28 CWDM 40km 1270nm 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 1270nm uses top quality DFB (Distributed Feedback Laser) transmitter and 25Gb/s APD receiver. 25G SFP28 CWDM 40km 1270nm 25GBASE-ER Lite supports DDM/DOM optical diagnostics that provide real-time diagnostic information about the present operating conditions. CWDM-25G-SFP28-40-27 operates in Standard 0°-70°C temperature range and has Double LC interface. CWDM-25G-SFP28-40-27 1270 nm 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-SFP28-40-27 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.

    25G SFP28 CWDM 40km 1270nm 25GBASE-ER Lite transceiver is CE/RoHS certified and is compliant with product safety standards. CWDM-25G-SFP28-40-27 is fully compliant to SFF-8431 and SFF-8472 Multi Source Agreement (MSA), IEEE 802.3by 25 Gb/s specification. Consequently, compliance to above standards guarantees that module is compatible and works with majority of networking equipment, where is not implemented special algorithm for protection against third party modules.
