10G Base LR 20km Compatible Transceiver Description
The EDGEOPTIC 10G-SFP-20 is a multi-vendor compatible 10G LR 20km SFP+ dual-fiber optical module engineered for long-reach 10 Gigabit Ethernet applications over single-mode fiber infrastructure. The 10G-SFP-20 operates at 1310nm wavelength for both transmission and reception, supporting data rates of 1G Ethernet (1.25 Gbps) and 10GBASE-LR (10.3125 Gbps) across multiple protocol standards and network applications. The 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-20 10G LR 20km 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 across multiple vendor equipment platforms. The 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 0 to 70C temperature range, with appropriate thermal considerations for sustained operation in controlled networking 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 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-20 is CE/RoHS certified and compliant with product safety standards.
The 10G-SFP-20 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 10.3125 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.
Frequently Asked Questions
When should I use 20km instead of 10km?
When your link budget requires more than 6dB. The 10G-SFP-10 has a 6dB budget suitable for links up to 10km. The 10G-SFP-20 provides 9dB, covering campus and inter-site links up to 20km. Calculate your total path loss (fiber at typically 0.32-0.35 dB/km + connectors + splices) to determine which module fits your link.
Is 10GBASE-LX the same as 10GBASE-LR 20km?
'10GBASE-LX' is not a defined IEEE standard for 10 Gigabit Ethernet. The 'LX' designation comes from 1000BASE-LX (IEEE 802.3z), which is 1 Gigabit Ethernet over single-mode fiber. The 10G-SFP-20 is a 10 Gigabit module with extended reach beyond the standard 10GBASE-LR 10km specification. The 'LX' label is sometimes used informally for 10G 20km modules, but it has no IEEE definition at 10G.
