Source Photonics compatible SPQ-CE-ER-CDFA Description
EdgeOptic's SPQ-CE-ER-CDFA compatible is a Source Photonics-coded 100GBASE-ER4 Lite QSFP28 transceiver built on our 100G-QSFP28-40 hardware platform. The module ships pre-programmed with the Source Photonics vendor identifiers for the SPQ-CE-ER-CDFA ordering code, so the optic identifies on the host as the OEM part. The CE prefix denotes the 100G Ethernet-only variant of this Source Photonics ER4 Lite family.
Optically the module conforms to the 100GBASE-ER4 Lite specification. Four LAN-WDM channels at 1295.56, 1300.05, 1304.58 and 1309.14 nm each carry 25.78125 Gbps NRZ, multiplexed onto one duplex LC single-mode fiber pair. The transmitter is an EML array; the receiver is an APD array, providing the additional sensitivity that distinguishes ER4 Lite from a standard LR4 build. Optical budget is 22 dB with host FEC, 18 dB without. ER4 Lite is not an IEEE 802.3ba or 802.3bm subclause and is not a 100G Lambda MSA grade; it is a generic 100GBASE-ER4 Lite specification used across vendor catalogs.
Reach is 40km on G.652 SMF with host RS-FEC enabled. Host-side FEC is the gating requirement for the 40km reach; the optic itself is transparent to FEC and contains no internal FEC engine. Engineers planning data-center interconnect or metro core links should confirm the host port has RS-FEC available on the 100GE MAC and verify both ends match during commissioning. SPQ-CE-ER-CDFM is the companion CE-suffix ordering reference in this family; SPQ-CS-ER-CDFA is the OTU4-capable dual-rate variant for platforms carrying OTU4 client traffic.
QSFP28 MSA SFF-8665 and SFF-8636 management compliance covers the electrical and software interfaces. DDM/DOM telemetry exposes per-lane TX and RX optical power, module temperature, supply voltage and laser bias current to the host for inspection and SNMP polling. The duplex LC connector accepts standard SMF patch cords. Power draw is bounded at 4.5 W maximum; the commercial 0 to +70 degC case-temperature range covers central-office and metro POP environments. Connector hygiene matters at ER4 Lite reach budgets; inspect and clean both end-faces before turn-up to avoid attenuation that erodes the FEC margin.
