10GBASE-ER SFP+ Transceiver: 10G-SFP-40
10GBASE-ER SFP+ Transceiver Overview
The 10G-SFP-40 is a 10GBASE-ER SFP+ module that extends 10 Gigabit Ethernet up to 40 km over single-mode fiber at 1550 nm. A 15 dB optical link budget supports metro and long-haul links well beyond standard LR reach, and the multi-rate envelope spans 1.25 to 11.32 Gbps, covering 1GE/10GE, 1G through 10G Fibre Channel, and STM-64 SONET/SDH on the same hardware. Duplex LC/UPC connectors, SFF-8431 host compatibility, and DDM/DOM diagnostics make it drop-in for carrier, service provider, and enterprise long-distance deployments.

10GBASE-ER SFP+ Transceiver Description
The EdgeOptic 10G-SFP-40 is a 10GBASE-ER SFP+ transceiver built for extended-reach 10 Gigabit Ethernet over single-mode fiber. Transmit and receive operate at 1550 nm with a DFB laser transmitter and PIN photodiode receiver. Transmit launch power is −1 to +4 dBm, receiver sensitivity is −16 dBm, and the receiver tolerates up to 0 dBm overload, yielding a 15 dB optical link budget that supports nominal 40 km reach on G.652 SMF within an 800 to 1000 ps/nm chromatic dispersion window. The multi-rate envelope covers 1.25 to 11.32 Gbps, so the same hardware carries 1GE and 10GE Ethernet, 1G/2G/4G/8G/10G Fibre Channel, and STM-64 SONET/SDH at 9.95 Gbps.
The hot-pluggable SFP+ form factor uses a duplex LC/UPC optical interface and a +3.3 V single supply. The electrical interface follows SFF-8431 MSA, which keeps the module drop-in across SFP+ host platforms from multiple vendors. EEPROM coding is configured per vendor to match host transceiver validation tables, so the 10G-SFP-40 registers cleanly on switches and routers that gate optics by vendor identity. SFF-8472 DDM/DOM reports transmit and receive optical power, module temperature, laser bias current, and supply voltage in real time over the 2-wire interface, which simplifies link commissioning and ongoing health monitoring.
Standards compliance covers IEEE 802.3ae for 10GBASE-ER, SFF-8431 and SFP MSA for the SFP+ host and electrical interface, and SFF-8472 for digital diagnostics. SONET/SDH STM-64 and 1G through 10G Fibre Channel are supported on the same optic. The module is CE marked and RoHS compliant, with Class 1 laser safety per IEC 60825-1 and FDA 21 CFR 1040.10. Standard operating temperature is 0 to 70 °C.
Typical deployments include metro Ethernet backhaul, carrier-class backbone segments, inter-building campus links, data center interconnect at distances beyond LR reach, and service provider long-haul where 1550 nm operation extends the budget compared with 1310 nm LR optics. The multi-rate envelope also makes the 10G-SFP-40 a single-SKU option for mixed Ethernet, SAN, and SONET/SDH segments. Ships next business day from EU stock with a lifetime warranty.

Frequently Asked Questions about 10GBASE-ER SFP+
When should I choose 10GBASE-ER over 10GBASE-LR for a long-distance link?
Pick 10GBASE-ER when the fiber run is longer than the 10 km LR design reach and up to 40 km on single-mode fiber. ER operates at 1550 nm, where standard G.652 SMF has lower attenuation than at the 1310 nm wavelength LR uses, which is what lets the same form factor cover the longer span. The 10G-SFP-40 carries a 15 dB optical budget for that 40 km reach. Inside 10 km, LR is usually the more economical choice.
Does the 10G-SFP-40 support 8G Fibre Channel alongside 10 Gigabit Ethernet on the same module?
Yes. The 10G-SFP-40 has a 1.25 to 11.32 Gbps data-rate envelope and is qualified for 1GE and 10GE Ethernet, 1G/2G/4G/8G/10G Fibre Channel, and STM-64 SONET/SDH on the same hardware. Teams consolidating SAN and Ethernet long-haul links into one optic do not need to order a separate FC-only part for the 8G FC segments.
What is the difference between 10GBASE-ER and 10GBASE-ZR, and which one reaches 80 km?
10GBASE-ER is the IEEE 802.3ae extended-reach standard for up to 40 km over single-mode fiber at 1550 nm; the 10G-SFP-40 sits in that envelope with a 15 dB link budget, DFB transmitter, and PIN receiver. 10GBASE-ZR is an industry term for ~80 km reach and is not a formal IEEE 802.3ae PMD, so the implementation is vendor-defined and typically requires a higher-power optical front end and a different receiver design. For runs up to 40 km on standard SMF, ER is the right pick; for 80 km links, a ZR-class optic is needed.
Does the 10GBASE-ER SFP+ module require chromatic dispersion compensation on standard OS2 single-mode fiber?
No external dispersion compensation is required for the 40 km design reach on standard G.652 OS2 fiber. The 10G-SFP-40 is rated for 800 to 1000 ps/nm of chromatic dispersion, which covers a 40 km link at typical 1550 nm dispersion coefficients on G.652 SMF. If a span includes high-dispersion fiber types, mixed legacy plant, or unusually long splice-extended runs, verify the end-to-end dispersion budget against the 800 to 1000 ps/nm window before deployment.
