The DWDM-SFP10G-3661-ER-C is a Cisco-compatible 10GBase-DWDM SFP+ transceiver operating at 1536.61 nm with a 40 km single-mode fiber reach.
It operates at a fixed DWDM wavelength of 1536.61 nm (ITU channel 61) for dense wavelength-division multiplexing applications.
This SFP+ module supports up to 40 km over single-mode fiber without external amplification.
A standard single-mode fiber (SMF-28 or equivalent) with an LC duplex connector is required for optimal performance.
Yes. It has been factory-tested to meet Cisco compatibility for guaranteed plug-and-play operation.
The module uses the SFP+ form factor with a duplex LC connector and a hot-pluggable electrical interface.
Yes. It complies with the SFF-8472 MSA for real-time digital monitoring of optical power, temperature, voltage and laser bias.
It operates reliably in the commercial temperature range of 0 °C to +70 °C and storage range of –40 °C to +85 °C.
It supports 10 G Ethernet (IEEE 802.3aq 10GBASE-LR) and CPRI up to option 8 for mobile backhaul.
Yes. The SFP+ design allows hot-swapping without powering down the host device or interrupting network traffic.
Yes. It is MSA-compliant and interoperable with any vendor’s 10G SFP+ ports that accept third-party optics.
Typical launch power is +0.5 to +5 dBm, with a receiver sensitivity of –24 dBm for a 10-12 BER performance.
It operates on a 3.3 V supply and consumes less than 1 W of power.
Insert the module into a compatible SFP+ port until it clicks, then attach LC-to-LC single-mode fibers following the correct transmit/receive orientation.
It includes a one-year limited warranty covering defects in materials and workmanship.
It delivers identical performance and compatibility at a lower cost, backed by stringent testing, while remaining fully MSA-compliant.
Check your device’s optics compatibility list and run a loopback or link test using built-in diagnostics to confirm proper operation.
