Source Photonics compatible SPQ-CE-ZR-CDFA Description
SPQ-CE-ZR-CDFA is Source Photonics' part number for a 100GBASE-ZR4 QSFP28 — 100G over 80 km single-mode fiber. Source Photonics makes this as OEM equipment for switch vendors, so you'll find it inside branded modules from various network equipment companies. If you've pulled a failed transceiver from a switch and the label says Source Photonics, this is likely the module you're looking to replace. EdgeOptic's compatible matches the original specs and is recoded for multi-vendor use.
The part number breaks down in Source Photonics' structured naming: SPQ for SFP/QSFP platform, CE for commercial temp, ZR for ZR4 reach, CDFA for the specific configuration. Four LAN WDM wavelengths — 1295.56, 1300.05, 1304.58, 1309.14 nm — cooled EML transmitters with PIN+SOA receiver. 30 dB link budget, 80 km on G.652 fiber, LC duplex. RS-FEC (RS-528,514) is mandatory on both ends. CE/RoHS certified, QSFP28 MSA SFF-8665 compliant, 0-70 °C commercial operating temperature.
Each of the four channels carries 25G for a 103.125 Gbps aggregate. Receiver sensitivity is better than -26.9 dBm — that's how you get the 30 dB budget for 80 km without external amplification or dispersion compensation. Power draw is about 5.5 W, typical for the ZR4 class. Standard QSFP28 MSA dimensions. ZR4 modules like this are commonly used for metro backbone, DCI, and ISP aggregation links.
RS-FEC (RS-528,514) on the host — mandatory. The module doesn't do FEC internally, so both ends need matching settings. And if you're running under about 15 km, put a 12 dB attenuator in the path. ZR4's TX power will overdrive the receiver on short spans.
QSFP28 MSA compliant, so it fits any host that supports ZR4 with RS-FEC. The original Source Photonics module was typically locked to one vendor's platform since it shipped as OEM stock. EdgeOptic's compatible removes that lock — recoded for broad multi-vendor use. DOM readings (TX/RX power, temp, voltage) show up normally via I2C, which is important on 80 km links where you want continuous monitoring of fiber plant health.

Frequently Asked Questions
Is the SPQ-CE-ZR-CDFA compatible with non-Source-Photonics switches?
Yes. EdgeOptic recodes the EEPROM for multi-vendor use. Any QSFP28 switch or router that supports ZR4 with host RS-FEC will recognize it. The original Source Photonics module was vendor-locked OEM stock — the compatible version removes that restriction.
Is RS-FEC required when using the SPQ-CE-ZR-CDFA?
Yes, mandatory. RS-FEC (RS-528,514) on the host side — the module doesn't do FEC internally. Both ends have to match. Mismatched FEC = link stays down.
Do I need an attenuator for short fiber runs with this ZR4 module?
Under about 15 km, yes — receiver overload risk. Put a 12 dB (or higher) LC attenuator inline. This isn't specific to the SPQ-CE-ZR-CDFA; it's a ZR4-class consideration across all vendors.
