Intel compatible SPTSLP4SLCDF Description
SPTSLP4SLCDF is the Intel part number for a single lambda 100G QSFP28 transceiver operating at 10km over duplex single-mode fiber. Intel-branded optics are used primarily with Intel E810 and X710 series network interface cards in server and storage environments. This module uses PAM4 modulation on a single optical lane at 106.25 Gbps with built-in FEC.
The transceiver operates in the 1304.5-1317.5nm wavelength range using an EML laser transmitter and PIN photodiode receiver. Integrated CDR circuitry handles signal recovery at PAM4 data rates. The module provides a minimum 6.3 dB optical link budget supporting 10km reach over standard G.652 single-mode fiber with LC duplex connectors.
Intel E810-CQDA2, E810-2CQDA2, and E810-XXVDA4 network adapters accept any MSA-compliant QSFP28 module without vendor validation. Unlike switch vendors such as Cisco or Arista, Intel NICs do not enforce transceiver vendor checks at the firmware or driver level. The ice driver (E810) and i40e driver (X710) read EEPROM data for DOM diagnostics but do not block third-party modules.
This EdgeOptic compatible SPTSLP4SLCDF is coded with Intel-recognized EEPROM data for correct identification in ethtool, Intel Ethernet Adapter Complete Driver Pack, and SNMP monitoring. DDM diagnostics report optical power levels, temperature, bias current, and supply voltage.
The module is based on the EdgeOptic 100G-QSFP28-SL10, compliant with the 100G Lambda MSA and QSFP28 MSA (SFF-8636/SFF-8665). CE/RoHS certified, Class 1 FDA and IEC60825-1 laser safety compliant. Maximum power consumption is 4.5W.
All EdgeOptic compatible transceivers undergo optical parameter measurements, connector cleanliness testing, and EEPROM validation before shipment. For volume pricing or platform-specific compatibility questions, contact our sales team.
Frequently Asked Questions
Do Intel E810 NICs require special configuration for the SPTSLP4SLCDF?
No. Intel E810 and X710 NICs follow standard QSFP28 MSA and do not enforce transceiver vendor validation. Any MSA-compliant QSFP28 module works plug-and-play. If the NIC does not detect the module, update the ice driver and NVM firmware via Intel’s Ethernet Adapter Complete Driver Pack rather than troubleshooting the optic.
What is the difference between SPTSLP4SLCDF and Intel’s older E100GQSFP28LR4?
SPTSLP4SLCDF is a single lambda PAM4 module transmitting 100G on one 1310nm wavelength with built-in FEC. E100GQSFP28LR4 uses four LAN-WDM wavelengths with NRZ modulation. Both reach 10km over duplex SMF but are not interoperable on the same link. The single-lambda design has fewer optical components and lower power consumption.
