ZTE compatible SFP-10GE-S20K Description
EdgeOptic's SFP-10GE-S20K compatible is a ZTE-coded 10G SFP+ transceiver built for 20 km single-mode runs on ZTE access, transport, and switching equipment. The SKU follows ZTE's naming pattern: S for single-mode, 20K for 20 km reach, sitting alongside the SFP-10GE-S10K (10 km) and SFP-10GE-S40K (40 km) in the same family. The compatible matches the original SFP-10GE-S20K specs and inherits its platform from the 10G-SFP-20 root.
1310 nm DFB laser, PIN photodiode receiver, 9 dB optical budget for 20 km spans on standard single-mode fiber. Site-specific fiber attenuation, connector, and splice loss should be field-verified against the link budget calculation for each deployment. SFF-8431 and SFF-8432 compliant SFP+ with duplex LC/UPC, OS1 or OS2 fiber, commercial 0 to 70 °C temperature range. Multi-rate support from 1.25 Gbps up to 11.32 Gbps covers GbE, 10GbE at 10.31 Gbps, and STM-64 at 9.95 Gbps for SDH backhaul on ZTE carrier transport nodes.
Compatible with the ZTE ZXA10 C300 OLT (10GE SFP+ uplinks on the XUTQ, SCTM, and HUTQ boards) and the ZTE ZXR10 8900-series routers and switches. Common deployments include 5G transport and mobile backhaul aggregation, FTTH OLT uplinks into ZTE access platforms, and SDH/Ethernet mixed-traffic spans on ZXR10 carrier nodes. Verify the specific board revision and firmware against ZTE's documentation before ordering for non-standard chassis. Full platform specs are on the 10G-SFP-20 product page.
DDM per SFF-8472 exposes TX/RX power, temperature, bias current, and voltage through ZTE's NMS or via the ZXR10 management CLI; verify the exact transceiver-monitoring command syntax against the Command Reference for your ZXR10 software release. Live optics monitoring catches fiber degradation early, which matters on OLT uplinks where a single failing span can affect hundreds of subscribers. EEPROM is coded with ZTE vendor identification so the host accepts the module without third-party transceiver alarms. CE, RoHS, and Class 1 laser safety per IEC 60825-1 and FDA.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For ZXA10 board-revision questions, ZXR10 firmware compatibility, or volume pricing, contact our sales team.
SFP-10GE-S20K Frequently Asked Questions
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 10GBASE-LR class module rated for 10 km. The S20K carries a higher 9 dB optical budget for 20 km reach, following ZTE's S{distance}K naming convention. The S20K runs on 10 km spans without issue since the extra budget gives headroom rather than overdrive, but on very short links under 1 km the received power can approach the overload threshold and an attenuator is the safe answer. Stocking the S20K covers both reach classes for sites that mix 10 km and 20 km uplinks.
How do I verify the SFP-10GE-S20K is recognized on a ZTE ZXR10 chassis?
On ZXR10 8900-series routers, run show opticalinfo interface <name> to display vendor identification, wavelength, and TX/RX power, or show optical-info brief interface <name> for a compact summary including temperature, voltage, and bias current. The output should show ZTE as the vendor with the matching SFP-10GE-S20K part field. ZTE's host check is EEPROM-based; there is no equivalent of the Cisco service unsupported-transceiver override or Juniper pic-mode bypass, so EEPROM coding is what carries the module through host recognition.

Does the SFP-10GE-S20K work in ZXA10 C300 OLT 10GE uplink slots?
Compatible with the ZXA10 C300 OLT, including the XUTQ 4-port 10GE uplink board and the SCTM and HUTQ uplink boards documented in ZTE's C300 manuals. EEPROM is programmed with ZTE vendor identification so the OLT accepts the module on its 10GE SFP+ ports without third-party transceiver alarms. Verify the specific board revision and ZXA10 firmware version against ZTE's compatibility documentation, or contact our sales team for confirmation on a particular C300 deployment.
