10G Base LX 20km Industrial Transceiver: 10G-SFP-20I

The EDGEOPTIC 10G-SFP-20I is an industrial multi-vendor compatible 10G LX 20km SFP+ dual-fiber optical module engineered for long-reach 10 Gigabit Ethernet applications over single-mode fiber infrastructure. The 10G-SFP-20I operates at 1310nm wavelength for both transmission and reception, supporting data rates of 1G Ethernet (1.25 Gbps) and 10GBASE-LX (10.3125 Gbps - 20km) across multiple protocol standards and network applications. The industrial 10G SFP+ 20km transceiver uses a DFB (Distributed Feedback) laser for transmission and a PIN photodiode for signal reception. The module has a 9dB guaranteed optical link budget, which determines the maximum transmission distance. Over G.652 single-mode fiber (SMF), the transceiver can reach up to 20 kilometers. Distance is an indicative parameter based on the minimum optical budget and average attenuation of optical cabling in the industry.

The 10G-SFP-20I 10G LX 20km module is a hot-pluggable industrial 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 across multiple vendor equipment platforms. The industrial 10G SFP+ 20km transceiver can be encoded to be compatible and operate in 80+ brands of networking 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 the SFF-8472 EEPROM interface and enables monitoring of transceiver operational parameters. The module operates within a -45 to 85C temperature range for reliable operation in harsh and extended temperature industrial environments.

Standards compliance includes IEEE 802.3ae for 10GBASE-LR, SFF-8431 for the SFP+ electrical interface, and SFF-8472 for DDM diagnostics. The 20km reach goes beyond the 10km 10GBASE-LR standard through an extended optical power budget. The industrial 10G SFP+ 20km 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. The 10G-SFP-20I is CE/RoHS certified and compliant with product safety standards.

The 10G-SFP-20I is designed for links that exceed the 10km range of standard 10GBASE-LR modules. Typical applications include campus inter-building connections, metro access rings, inter-site enterprise WAN links, and service provider infrastructure deployments where single-mode fiber runs between 10 and 20km. The dual-rate capability accommodates 1G Ethernet operation at 1.25 Gbps alongside native 10 Gigabit rates at 11.32 Gbps, providing operational flexibility for mixed-speed network deployments. All modules undergo quality testing before delivery, including optical parameter measurements, connector cleanliness tests, and SFP+ transceiver EEPROM memory data validation.
