10G CWDM SFP+ 40km Industrial Transceiver Description
The CWDM-10G-SFP-40I is EdgeOptic's industrial-temperature 10G CWDM SFP+ transceiver, built for 40 km over single-mode fiber at a 16 dB average link budget. The transmitter covers a 14-channel CWDM plan across 1270 to 1610 nm, excluding the 1390, 1410, 1430 and 1450 nm channels from the standard 18-channel ITU-T G.694.2 CWDM grid. The receiver passband spans the full 1270 to 1610 nm range to match downstream mux and demux equipment.
Operating from -40°C to +85°C, the module targets outdoor cabinets, cell-tower fronthaul, substations and other sites without climate control, where the standard 0°C to 70°C CWDM-10G-SFP-40 does not meet the environmental requirement. Optical output ranges from -3 dBm to 3 dBm, receiver sensitivity is -16 dBm with a 0.5 dBm overload point, on a DFB laser transmitter and PIN photodiode receiver with 400 to 800 ps/nm dispersion tolerance.
The transceiver supports a multi-rate envelope from 1.25 to 11.32 Gbps: 10G Ethernet at 10.31 Gbps, 1G through 10G Fibre Channel spanning 1.0625 to 10.52 Gbps, OTN applications including ODU2, ODU2e, OTU1e, OTU1f, OTU2, OTU2e and OTU2f, and STM-64 SONET/SDH at 9.95 Gbps. DDM/DOM monitoring reports transmit power, receive power, bias current, supply voltage and temperature. It ships in a duplex LC/UPC SFP+ form factor per the SFP MSA and SFF-8431, runs on a single 3.3V supply, and is CE, RoHS and Class 1 FDA/IEC 60825-1 laser safety compliant.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, the CWDM-10G-SFP-40I is covered by EdgeOptic's lifetime warranty. For channel selection guidance or project quantity pricing, contact our sales team.
Frequently Asked Questions
What is the difference between C-Temp and I-Temp transceivers?
C-Temp (commercial temperature) transceivers are rated for 0°C to 70°C, matching typical indoor data center and network closet environments. I-Temp (industrial temperature) transceivers, including the CWDM-10G-SFP-40I, are rated for a wider -40°C to +85°C range for outdoor and non-climate-controlled sites. The base CWDM-10G-SFP-40 root product is the C-Temp part at 0°C to 70°C; do not substitute it in an application that requires I-Temp assurance.
Which CWDM wavelengths are available on this 14-channel module?
The ITU-T G.694.2 CWDM grid defines 18 channels at 20 nm spacing from 1271 to 1611 nm. The CWDM-10G-SFP-40I covers 14 of those channels across the 1270 to 1610 nm transmit range, excluding the 1390 nm, 1410 nm, 1430 nm and 1450 nm channels. Confirm the specific channel wavelength ordered against the target CWDM mux and demux port assignment before deployment to avoid a wavelength mismatch.
