100G CFP2 40km ER4 Transceiver: 100G-CFP2-40

Our EDGEOPTIC 100G-CFP2-40 is a multi-vendor compatible 100GBASE-ER4 CFP2 optical module engineered for extended-reach 100 Gigabit Ethernet applications operating over single-mode fiber networks. The 100G-CFP2-40 module implements 4-channel LAN WDM technology utilizing wavelengths at 1295.56nm, 1300.05nm, 1304.58nm, and 1309.14nm for both transmission and reception, delivering aggregate data rates up to 112 Gbps with OTU4 optical transport network support. Our 100G CFP2 ER4 transceiver incorporates EML (Electro-absorption Modulated Laser) technology for transmission paired with high-sensitivity PIN photodiode array for reception, optimized for long-haul performance requirements.

The transceiver provides an exceptional 18 dB guaranteed optical link budget, enabling transmission distances up to 40 kilometers over standard single-mode fiber infrastructure. Each of the four optical lanes operates at approximately 25 Gbps using NRZ (Non-Return to Zero) modulation, with precisely controlled average launch power of 2.9 dBm per lane. The enhanced receiver sensitivity of -20.9 dBm per lane combined with overload tolerance up to 4.5 dBm accommodates significant span loss variations typical in metropolitan and regional network deployments. While CFP2 represents a legacy form factor approaching end-of-life phase in newer installations, these modules remain critical for maintaining existing long-haul 100G infrastructure and providing economical solutions where CFP2 interfaces are already established.

100G-CFP2-40 compatible module features hot-pluggable deployment with duplex LC connectors serving as the optical interface. The electrical interface adheres to CFP2 MSA specifications, ensuring seamless compatibility with standard CFP2 host systems across diverse vendor equipment. Our 100GBASE-ER4 CFP2 transceiver supports encoding for compatibility with 80+ equipment brands through customized EEPROM programming. The module integrates comprehensive DDM/DOM (Digital Diagnostic Monitoring) capabilities, delivering real-time telemetry including per-lane transmitted and received optical power, module temperature, laser bias current, and supply voltage via the MSA-compliant management interface.

Standards compliance includes IEEE 802.3ba for 100 Gigabit Ethernet extended reach applications and OTU4 compatibility for carrier-grade transport networks. The integrated CDR (Clock and Data Recovery) functionality maintains signal integrity across the full 40km operational distance. Operating within 0 to 70°C temperature range with single +3.3V power supply, the module delivers consistent performance in controlled data center and central office environments. Our 100G CFP2 ER4 transceiver maintains CE and RoHS certifications, complying with Class 1 FDA and IEC60825-1 laser safety standards.

Primary applications encompass metropolitan area network backbones, inter-data center connectivity, service provider aggregation networks, and enterprise campus extensions. The 40km reach capability addresses critical requirements for city-wide network integration and disaster recovery site interconnection without requiring optical amplification. Our quality assurance protocols include rigorous testing covering optical parameter verification, connector cleanliness inspection, and comprehensive EEPROM data validation ensuring reliable field deployment.
