Source Photonics SPP-10E-SR-CDFF Compatible 10GBASE-SR SFP+

Source Photonics, a CommScope subsidiary headquartered in West Hills, California, ships the SPP-10E enterprise 10GBASE-SR SFP+ family into large-scale data center deployments. The SPP-10E-SR-CDFF is a specific coded variant in this family, where the CDFF designator identifies a customer EEPROM profile rather than an optical change. Optically the module matches the base SPP-10E-SR: same 850 nm VCSEL transmitter, same 6.1 dB minimum link budget, same dual LC interface. EdgeOptic's compatible replicates the CDFF vendor data so the target host accepts the module under its supported optics policy.

The module is built to IEEE 802.3ae Clause 52 for 10GBASE-SR operation, with electrical compliance per SFF-8431 and mechanical per SFF-8432. A 850 nm VCSEL transmitter delivers -7.3 to -1 dBm launch power into OM3 or OM4 multimode fiber through a dual LC duplex interface, with a PIN photodiode receiver rated to -9.9 dBm sensitivity. Reach is 300 m on OM3 and 400 m on OM4 at 10.3125 Gbps. Full DDM/DOM diagnostics follow SFF-8472, exposing laser bias, optical Tx and Rx power, case temperature, and supply voltage to the host NMS. Commercial 0 to 70 °C grade covers typical data center and enterprise switching environments.

Because the CDFF coding is specific to one customer profile, it is not interchangeable with other SPP-10E-SR variants even though the optical hardware is identical. Network engineers replacing an existing module in production should pull show transceiver output before ordering and match the reported vendor name, part number, and serial number prefix to confirm the coding profile. Source Photonics ships a broad OEM catalog into many networking brands, so the physical module may resemble branded optics from a major host vendor; the EEPROM is what the host validates against during insertion. The host-side error signature is usually a supported-optics warning followed by the port staying in err-disabled or admin-down state.
