Source Photonics compatible SPQ-CS-ER-CDFM Description
EdgeOptic's SPQ-CS-ER-CDFM compatible is a Source Photonics-coded QSFP28 transceiver carrying both 100G Ethernet and OTU4 over a 40 km LAN-WDM single-mode link. Source Photonics' own product page lists the data-rate range as 103.1 to 111.8 Gb/s, which covers 100G Ethernet at 103.125 Gbps and OTN OTU4 at 111.81 Gbps. Engineers picking this CS-suffix variant over the 100GE-only SPQ-CE-ER-CDFM sibling are doing so because they need OTU4 client transport on the same optical plant.
Optical layer: four LAN-WDM channels at 1295.56, 1300.05, 1304.58 and 1309.14 nm, EML transmitters, APD receivers. Optical link budget is 22 dB with host FEC and 18 dB without FEC, supporting 40 km on duplex single-mode fiber with an LC connector. Maximum power draw is 4.5 W on a +3.3 V rail, commercial 0 to 70 °C. DDM/DOM is supported per SFF-8636 so live Tx/Rx power, bias current and temperature can be read from the host.
Whether OTU4 client traffic actually runs depends on the host platform's port mode and OTN licensing; verify the chosen port supports OTN framing before commissioning. The EEPROM is coded for recognition on platforms that ship the SPQ-CS-ER-CDFM part number, so the module enumerates cleanly without vendor-specific unsupported-transceiver workarounds. The 100GE-only SPQ-CE-ER-CDFM sibling remains the right choice for deployments without OTN transport.
Hardware compliance: QSFP28 MSA per SFF-8665, management per SFF-8636, CE and RoHS certified. Typical deployments are carrier 40 km metro links, ISP backbone aggregation, mobile core transport and data center interconnect where OTU4 client mapping into a transport layer is required.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For dual-rate SPQ-CS-ER-CDFM deployments or sibling SKU questions, contact our sales team.
