Will this 1470nm CWDM SFP+ work in our Cisco switches for a 10G uplink?

Yes. LINK-PP LS-CW4710-10C CWDM modules are tested to be compatible with Cisco switches and routers, and the LS-CW4710-10C follows the SFP+ MSA, so it fits standard SFP+ slots. For CWDM deployments, you’ll pair it with a CWDM MUX/DEMUX on the fiber side.

Can this LS-CW4710-10C SFP+ optical transceiver transmit through passive 8-channel or 18-channel CWDM MUX/DEMUX units?

Yes. The 1470nm wavelength matches ITU-T G.694.2 grid channel specifications, making it fully compatible with standard passive CWDM multiplexers.

Does temperature affect the 1470nm central wavelength accuracy in our CWDM Mux/Demux?

The internal DFB laser is designed to stay within standard CWDM channel passbands (±6.5nm) across the full 0°C to +70°C range, ensuring no channel dropouts on standard 20nm-spaced multiplexers.

Our core uses 1550nm for long-haul. Can 1470nm run on the same fiber pair without interference?

Yes, if you use a CWDM MUX/DEMUX. 1470nm and 1550nm are separate CWDM channels; the MUX isolates them so they share the same fiber pair without crosstalk. Just map each wavelength to its dedicated MUX port end-to-end.

Our enterprise data center migration required aggregating 10G storage arrays and server clusters over existing single-mode fiber pairs without laying new conduit. We opted for these 10G CWDM 1470nm SFP+ transceivers paired with passive multiplexers. The build quality of the metal housing is rugged, providing effective EMI shielding and secure mechanical latching in high-density switch fabrics. Live hot-swapping did not introduce electrical noise or transient voltage dips on adjacent active ports. Thermal dispersion is well-managed, maintaining 41°C steady-state inside a 60% fan-duty chassis. Fully compliant with SFF-8431, SFF-8432, and SFF-8472 specifications. Highly recommended for cost-effective capacity scaling.

Bought 20 pcs for a metro access ring, all channels aligned perfectly on the 1470nm slot. DDM shows stable TX around -2 dBm, and RX sensitivity is good for our 6 - 8km spans. No need to tweak anything, just plug and go.

We standardized on 10G CWDM for our metro WAN to reduce fiber count. The LS-CW4710-10C 1470nm SFP modules are now our default for short-to-mid range hops (5 - 8 km). DOM integration lets us get alerts when TX/RX drifts beyond thresholds, and the duplex LC connectors work seamlessly with our existing patch infrastructure. Over six months, across ~120 ports, we’ve had zero RMA requests and the link uptime is indistinguishable from our DWDM core. For enterprise network teams wanting simple, scalable 10G CWDM, this SFP+ module is a solid pick.

We installed 16 units in weather-protected cabinets feeding base stations. Ambient temps swing from 5°C at night to ~55°C in direct sun, still within the 0 - 70°C commercial range. The DFB CWDM lasers stayed stable, no wavelength drift was observed on the MUX side, and the PIN receivers maintained clean eye diagrams under full load. DOM temperature and power alarms are correctly mapped in our NMS, which helps us catch fiber degradation early. For telco access networks that don’t need industrial (-40 - 85°C) grade, this is a cost-effective choice.

We built a 10G CWDM ring across four buildings using 1470/1490/1510/1530nm channels. The LS-CW4710-10C modules on the 1470nm leg showed consistent TX power between -4.5 and -1.5 dBm and RX levels well above the -14.5 dBm sensitivity threshold even on our longest 8.2 km span. DOM data matched our external power meter within ±0.3 dB, and after a 72-hour stress test with line-rate traffic we recorded zero packet loss or CRC errors. For commercial indoor/covered outdoor runs up to 10 km, these are a no-brainer.
