Intel compatible SPTSQP4LLCDF 100GBASE-LR4 /OTU4 Dual Rate QSFP28 Module

EdgeOptic's SPTSQP4LLCDF compatible is an Intel-coded 100GBASE-LR4 QSFP28 transceiver built on the EdgeOptic 100G-QSFP28-10 platform, supporting dual-rate operation across 100G Ethernet and OTU4 transport on the same LAN-WDM wavelength plan. The Intel ordering code SPTSQP4LLCDF is listed in the Intel ARK catalogue under SKU 209802 for the Intel Silicon Photonics 100G LR4 QSFP28 Optical Transceiver. EdgeOptic's compatible carries the SPTSQP4LLCDF ordering code so procurement records and chassis inventory output stay consistent with the part number called out in the equipment configuration.

The optical interface follows IEEE 802.3ba Clause 88 100GBASE-LR4 and ITU-T G.709 OTU4 4I19D1F. Four NRZ lanes on the LAN WDM grid at 1295.56, 1300.05, 1304.58, and 1309.14 nm multiplex onto a single LC duplex pair of G.652 single-mode fiber. In 100GBASE-LR4 mode the aggregate line rate is 103.125 Gbps; in OTU4 transport mode the aggregate is 111.81 Gbps on the same wavelength plan, giving a single SKU that covers both Ethernet uplink and OTN client-side roles. The 6.3 dB optical path loss budget supports a full 10 km reach on G.652 SMF.

On the host side the module follows the QSFP28 MSA SFF-8665 form factor with SFF-8636 management. The electrical interface is CAUI-4 per IEEE 802.3bm, four lanes of 25 Gbps NRZ. The module operates on a single 3.3 V supply and reports DDM telemetry for tx power, rx power, bias current, supply voltage, and case temperature. Operating case temperature is 0 to 70°C commercial. Class 1 laser safety classification, RoHS compliant, CE marked. Typical deployment scenarios include ISP aggregation and backbone, mobile operator core networks, OTN client-side interfaces on muxponders and transponders, and data-center site interconnects on QSFP28 hosts that accept third-party 100GBASE-LR4 optics per the QSFP28 MSA.

Don't confuse the SPTSQP4LLCDF with the sibling SPTSBP4LLCDF Intel ordering code. Both are Intel ordering codes within the Silicon Photonics 100G LR4 QSFP28 family, and both share the same 100GBASE-LR4 optical interface. Match the exact ordering code on the equipment label or in the equipment compatibility list before placing a replacement order; the two codes are tracked separately in chassis inventory output and procurement records.

Verify the entry for your specific NIC, switch, router, or muxponder in the vendor's transceiver compatibility matrix before deployment.
