ZTE compatible SFP-10GE-S20K Description
SFP-10GE-S20K is ZTE's part number for a 10G SFP+ transceiver. The naming is straightforward — S for single-mode, 20K for 20 km reach. It sits alongside the SFP-10GE-S10K (10 km) in ZTE's SFP+ lineup. EdgeOptic's compatible is built on the 10G-SFP-20 platform and works across ZTE access, transport, and switching equipment.
1310 nm DFB laser, PIN receiver, 9 dB optical budget — 20 km on standard single-mode at typical 0.35 dB/km plus connectors and splices. Real-world reach depends on fiber condition, splice count, and connector quality, but 20 km is conservative for most plant. On a clean 20 km route with four connectors and a few splices, roughly 8 dB of the 9 dB budget is consumed. SFF-8431/8432 compliant SFP+ with duplex LC/UPC. Runs on OS1 or OS2 fiber. Commercial temp range, 0-70 °C.
Multi-rate from 1.25 to 11.32 Gbps — covers GbE, 10GbE, STM-64 at 9.95 Gbps, and OTU2 with FEC overhead. In ZTE FTTH networks, the SFP-10GE-S20K typically goes into the 10GE uplink slots on OLT platforms like the ZXA10 C300 (XUTQ board). It also handles SDH/SONET backhaul on ZTE carrier transport nodes for mixed-traffic environments. Verify the specific board revision and firmware version before ordering. Full platform specs on the 10G-SFP-20 product page.
DDM per SFF-8472 — TX/RX power, temp, bias current, voltage, all visible through ZTE's NMS. Critical for catching fiber issues before they become outages, especially on OLT uplinks where a single degraded span can affect hundreds of subscribers. EEPROM is coded with ZTE vendor identification for clean host recognition. EdgeOptic programs transceivers for 80+ vendor platforms from the same production line, and each SFP-10GE-S20K unit gets tested against ZTE equipment for proper ID and link-up.

Frequently Asked Questions
Is the SFP-10GE-S20K compatible transceiver suitable for ZXA10 C300 OLT 10GE uplink ports?
Yes, coded for ZTE and tested in the 10GE SFP+ slots on the ZXA10 C300, including the XUTQ 4-port 10GE uplink board. EEPROM carries ZTE vendor ID so it matches the expected module profile. Confirm the specific board revision and firmware version with EdgeOptic sales before ordering if there is any uncertainty.
What is the difference between ZTE SFP-10GE-S10K and SFP-10GE-S20K?
Same 1310 nm wavelength, same SFP+ form factor. The S10K is a standard 10GBASE-LR at 10 km. The S20K has a higher optical budget (9 dB) for 20 km reach. The S20K works on 10 km spans too — extra margin doesn't cause problems. Only watch for very short runs under 1 km where received power might approach the overload point. For mixed-distance deployments, stocking just the S20K simplifies inventory to one part number.
Can the SFP-10GE-S20K compatible module handle STM-64 traffic on ZTE transport equipment?
Yes — STM-64 at 9.95 Gbps, 10GbE, GbE, and OTU2 up to 11.32 Gbps. ZTE carrier transport nodes running SDH for mobile backhaul can use the same module for Ethernet traffic. No hardware swap needed.
