ZTE SFP-10GE-S80K Compatible 10GBASE-ZR SFP+ 80km Module

EdgeOptic's SFP-10GE-S80K compatible is a ZTE coded version of the EdgeOptic 10G-SFP-80 multi-vendor 10GBASE-ZR transceiver. It is a duplex single-mode SFP+ module that carries 10 Gigabit Ethernet over a 1550 nm wavelength to 80 km, programmed with ZTE-recognized EEPROM so the host reads it as a genuine SFP-10GE-S80K. The same EdgeOptic 10GBASE-ZR module ships under multiple vendor codes; this listing is the ZTE variant.

The optics use an EML transmitter and an APD receiver to deliver a 23 dB link budget across the 80 km span. Transmit power runs 0 to +5 dBm and receive sensitivity is better than −24 dBm, with a chromatic dispersion tolerance of 1600 ps/nm. Both transmit and receive operate at 1550 nm over a duplex LC/UPC interface on standard G.652 single-mode fiber. Digital diagnostics monitoring is supported, so transmit power, receive power, laser bias, temperature, and supply voltage are all readable from the host for commissioning and ongoing fault isolation.

ZTE uses the SFP-10GE-S80K in the 10 Gigabit Ethernet SFP+ ports on its ZXR series switches and routers, where it provides a 1550 nm ZR uplink across long single-mode spans. Scope here is 10GbE. The module also handles Gigabit Ethernet at the lower rate edge for mixed-speed slots that allow it. ZTE offers this reach class in both SFP+ and XFP form factors; the SFP-10GE-S80K is the SFP+ variant, which will not fit an XFP cage, so confirm the required form factor for your ZXR slot before ordering. Verify the slot assignment against the transceiver table for your ZXR platform before deployment.

The EdgeOptic build is rated for the standard 0 to 70 C commercial range and runs from a single +3.3V supply, which keeps thermal and power behavior aligned with the rest of a 10GbE line card. The 80 km reach assumes standard single-mode fiber within the 23 dB link budget and the 1600 ps/nm dispersion limit; on longer or higher-loss spans, measure the end-to-end loss during commissioning and confirm receive power sits above the −24 dBm sensitivity floor.

Each module is built to the SFF-8431 SFP+ MSA and carries CE, RoHS, and Class 1 laser safety certification per IEC 60825-1 and the FDA. 10GBASE-ZR is an industry de-facto MSA reach class derived from OC-192/STM-64 optics, not an IEEE 802.3ae mode, so interoperability follows the SFP+ MSA rather than an IEEE clause. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.
