Source Photonics compatible SP-25E-LR-xDFD Description
EdgeOptic's SP-25E-LR-xDFD compatible is a Source Photonics-coded version of the EdgeOptic 25G-SFP28-10 multi-vendor 25GBASE-LR transceiver. It carries the EEPROM identification a Source Photonics-equipped host expects, so it drops into 25GBASE-LR slots and reports through the host management interface like the original module. One universal EdgeOptic part covers multiple vendor codes, and this listing is the Source Photonics build of it.
The module is a 25GBASE-LR SFP28 transceiver operating at 1310 nm over duplex single-mode fiber, reaching 10 km on a Double LC/UPC connection. It carries a 5 dB average optical path loss budget. Transmit launch power runs from a minimum of −7 dBm to a maximum of +2 dBm, receiver sensitivity is rated at −12 dBm, and the receiver tolerates an overload of +3 dBm. The host sets up the link to IEEE 802.3cc; the module itself does not perform forward error correction, so any FEC runs on the host side when the host enables it.
The transceiver runs both 25G Ethernet at 25.78 Gbps and 10G Ethernet at 10.31 Gbps, with supported serial rates of 8.5 and 25.78 Gbps, so a single part covers 25G aggregation links and 10G connections on the same fiber plant. DDM/DOM is supported, giving the host live readings of transmit power, receive power, laser bias, temperature, and supply voltage for in-service monitoring. Power draw is held to 1.2 W maximum, and the module operates across the 0 to 70 °C commercial temperature range. It is built to the SFP28 MSA and SFF-8431, SFF-8432 and SFF-8472 specifications, and is CE marked, RoHS compliant, and Class 1 laser safe.
Common applications include ISP fiber aggregation and backbone links, mobile backhaul, and data center site interconnect within the 10 km single-mode reach. The SP-25E-LR family uses an x temperature wildcard in the part number: SP-25E-LR-CDFD is the commercial 0 to 70 °C build, and SP-25E-LR-IDFD is the industrial build. This EdgeOptic compatible matches the commercial CDFD grade; for industrial temperature deployments, contact our sales team.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, the SP-25E-LR-xDFD compatible ships next business day from EU stock with a lifetime warranty.
Frequently Asked Questions
What is the difference between the SP-25E-LR-xDFD and the SP-25E-LR-xDFR?
They are different reach classes in the same Source Photonics SP-25E family. The SP-25E-LR-xDFD is a 10 km 25GBASE-LR SFP28, while the SP-25E-LR-xDFR is a 2 km LR Lite module. If a link runs longer than 2 km, the xDFD is the correct part. The EdgeOptic SP-25E-LR-xDFD compatible on this page is the full 10 km 25GBASE-LR transceiver.
Does the SP-25E-LR-xDFD compatible cover the commercial (C) or industrial (I) temperature grade?
The x in SP-25E-LR-xDFD is a temperature-grade wildcard: C is the commercial 0 to 70 °C build (SP-25E-LR-CDFD) and I is the industrial build (SP-25E-LR-IDFD). The EdgeOptic compatible is rated for the commercial 0 to 70 °C range and matches the CDFD grade. If the deployment requires industrial temperature operation, contact our sales team before ordering.
