10G Base LR 20km Compatible Transceiver Description
EdgeOptic's 10G-SFP-20 is a multi-vendor compatible, multi-protocol 20km extended-reach SFP+ transceiver for 10 Gigabit single-mode fiber infrastructure. The module operates at 1310nm for both transmission and reception, with a DFB (Distributed Feedback) laser transmitter and a PIN photodiode receiver. Supported applications include 10 Gigabit Ethernet (10.3125 Gbps), 1 Gigabit Ethernet (1.25 Gbps), 1G/2G/4G/8G/10G Fibre Channel, and STM-64 SONET (9.95 Gbps). The 9 dB optical link budget covers G.652 single-mode fiber runs up to 20km. Distance is an indicative parameter based on the minimum optical budget and average industry attenuation.
The 10G-SFP-20 is a hot-pluggable SFP+ module with duplex LC/UPC connectors as the optical interface. The electrical interface conforms to SFF-8431 MSA, ensuring compatibility with standard SFP+ host systems across vendor equipment. The module incorporates DDM/DOM (Digital Diagnostic Monitoring) per SFF-8472, providing real-time transmitted and received optical power, module temperature, bias current, and supply voltage. Operation is specified across the 0 to 70 degree C commercial temperature range. CE, IEC60825-1 Class 1 laser safety, and RoHS compliance apply.
The 20km reach extends beyond the IEEE 802.3ae 10GBASE-LR 10km / 6.2 dB specification through a wider 9 dB optical power budget. Multi-vendor interoperability is achieved through SFP+ MSA adherence; equipment with vendor-specific module validation may require custom EEPROM coding. EdgeOptic provides custom EEPROM coding for major networking platforms across the catalog of compatible variants below. Equipment compatibility should be verified against the host vendor's transceiver matrix.
The 10G-SFP-20 is the extended-reach face of EdgeOptic's 10G LR SFP+ platform. For applications matching the standard IEEE 10GBASE-LR 10km / 6.2 dB datasheet face, see the 10G-SFP-10 sibling. For 20km links and applications where path loss exceeds the standard 10GBASE-LR 6.2 dB budget, the 10G-SFP-20 is the correct face. Typical deployments include campus inter-building connections, metro access rings, inter-site enterprise WAN links, and service provider infrastructure where SMF runs between 10 and 20km, including mixed-rate environments combining 1GbE, 10GbE, Fibre Channel, and STM-64 SONET on common fiber plant.
All modules ship from EU stock with next business day delivery and a lifetime warranty, backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms.
10G-SFP-20 Frequently Asked Questions
When should I use 20km instead of 10km?
When the link budget requires more than 6.2 dB. The 10G-SFP-10 has a 6.2 dB budget per IEEE 802.3ae Clause 52, suitable for 10GBASE-LR links up to 10km. The 10G-SFP-20 provides 9 dB, covering campus and inter-site links up to 20km. Calculate total path loss (fiber typically 0.34 dB/km at 1310nm per ITU-T G.652 plus connectors and splices) to determine which face fits the 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.
