10G Base ZR+ 120km Compatible Transceiver: 10G-SFP-120

Our EDGEOPTIC 10G-SFP-120 is a multi-vendor compatible 10G Base ZR+ SFP+ dual-fiber optical module engineered for maximum-reach 10 Gigabit Ethernet applications over single-mode fiber infrastructure. The 10G-SFP-120 module operates at 1550nm wavelength for both transmission and reception, supporting data rates from 1.25 to 11.32 Gbps across multiple protocol standards and network applications. Our 10G Base ZR+ SFP+ transceiver utilizes CFL (Cooled Fiber Laser) technology for transmission and high-sensitivity APD (Avalanche Photodiode) for signal reception. The CFL laser technology provides superior optical performance characteristics, including enhanced wavelength stability and reduced chirp, enabling exceptional transmission quality over ultra-long distances. The transceiver ensures a 28 dB guaranteed optical link budget, which determines the maximum transmission distance capabilities. Over single-mode fiber (SMF), the transceiver can reach distances up to 120 kilometers under optimal conditions, with exceptional chromatic dispersion tolerance of 2400 ps/nm enabling reliable transmission over extended fiber spans with minimal signal degradation. However, distance is just an indicative parameter calculated for comfort of identification – eventually we calculate distance taking into account minimal optical budget and average attenuation of optical cabling in industry.

10G-SFP-120 compatible 10G Base ZR+ module is a hot-pluggable SFP+ transceiver with duplex LC/UPC connectors as the optical interface. The electrical interface conforms to SFF-8431 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP+ host systems supporting multiple vendor equipment platforms. Our 10G Base ZR+ SFP+ transceiver can be encoded to be compatible and successfully operate in different 80+ brands of network equipment. The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time information including transmitted and received optical power levels, module temperature, bias current, and supply voltage. This diagnostic data is available via MSA-compatible EEPROM interface and enables monitoring of transceiver operational parameters. The module operates within a 0 to 70°C temperature range, with appropriate thermal considerations for sustained operation in controlled server room environments.

Standards compliance includes IEEE 802.3ae for 10 Gigabit Ethernet, along with SDH/SONET specifications and Fiber Channel support. The transceiver achieves multi-vendor interoperability through adherence to industry MSA standards, though equipment with vendor-specific module validation may require custom EEPROM programming for compatibility. Our 10G SFP+ ZR+ transceiver is CE/RoHS certified, and it is compliant with product safety standards.

Typical applications are ultra-long-haul carrier-class backbone infrastructure, wide area network deployments spanning large geographic regions, inter-regional telecommunications networks, submarine cable landing stations, and dark fiber implementations requiring absolute maximum distance capabilities without inline amplification or signal regeneration. The multi-rate capability accommodates legacy Gigabit Ethernet operation at 1.25 Gbps alongside native 10 Gigabit rates, providing operational flexibility for mixed-speed network deployments. Because our focus is providing top quality service, we are performing serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanness tests and SFP+ transceiver EEPROM memory data validation tests.
