# Product Documentation
# Product Description

    LWDM-25GFH-SFP28-40-XX is LAN WDM 25GE ER eCPRI (enhanced CPRI) / CPRI Fronthaul 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 17.4 dB, which in most cases is enough to reach 40 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. LWDM-25GFH-SFP28-40-XX uses top quality DFB (Distributed Feedback Laser) transmitter and 25Gb/s APD (Avalanche photodiode) receiver. LWDM-25GFH-SFP28-40-XX LWDM Ch. 277 – Ch. 309 (1277.89nm – 1309.14nm) 25GE ER eCPRI / CPRI supports DDM/DOM optical diagnostics that provide real-time diagnostic information about the present operating conditions. LWDM-25GFH-SFP28-40-XX operates in Standard 0°-70°C temperature range and has Double LC interface. LWDM-25GFH-SFP28-40-XX LWDM Ch. 277 – Ch. 309 (1277.89nm – 1309.14nm) 25GE ER eCPRI / CPRI SFP28 support 8.5-28.1 Gbps data rate and eCPRI / CPRI Option 10 (24.33 Gbps), CPRI Option 9 (12.165 Gbps), CPRI Option 8 (10.138 Gbps), CPRI option 7 (9.830 Gbps) applications. LWDM-25GFH-SFP28-40-XX 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 Mobile Carrier Networks, thus 5G fronthaul and O-RAN (open radio access network) applications.

    LWDM-25GFH-SFP28-40-XX LWDM Ch. 277 – Ch. 309 (1277.89nm – 1309.14nm) 25GE ER eCPRI / CPRI SFP28 transceiver is CE/RoHS certified and is compliant with product safety standards. LWDM-25GFH-SFP28-40-XX is fully compliant to SFF-8431 and SFF-8472 Multi Source Agreement (MSA), eCPRI, CPRI and 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. However – our technical team has accumulated deep expertise in custom-encoded firmware’s for LWDM 25GE ER eCPRI / CPRI SFP28 transceiver in order to make it work in almost any brand equipment. We will be glad to know your requirements.
