10G CWDM SFP+ 40km Transceiver: CWDM-10G-SFP-40

Our EDGEOPTIC CWDM-10G-SFP-40 is a multi-vendor compatible 10G CWDM SFP+ dual-fiber optical module engineered for wavelength division multiplexing 10 Gigabit Ethernet applications over single-mode fiber infrastructure. The CWDM-10G-SFP-40 module operates across the CWDM wavelength grid from 1270nm to 1610nm with 18 available channels, supporting data rates from 1.25 to 11.32 Gbps across multiple protocol standards and network applications. Our 10G CWDM SFP+ transceiver utilizes DFB (Distributed Feedback) laser technology for transmission and PIN photodiode for signal reception. The transceiver ensures a 16 dB guaranteed optical link budget, which determines the maximum transmission distance capabilities. Over single-mode fiber (SMF), the transceiver can reach distances up to 40 kilometers under optimal conditions. However, distance is just an indicative parameter calculated for comfort of identification – eventually we calculate distance taking into account minimal optical budget and average attenuation of optical cabling in industry.

CWDM-10G-SFP-40 compatible 10G CWDM module is a hot-pluggable SFP+ transceiver with duplex LC/UPC connectors as the optical interface. The electrical interface conforms to SFF-8431 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP+ host systems supporting multiple vendor equipment platforms. Our 10G CWDM SFP+ transceiver can be encoded to be compatible and successfully operate in different 80+ brands of network equipment. The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time information including transmitted and received optical power levels, module temperature, bias current, and supply voltage. This diagnostic data is available via MSA-compatible EEPROM interface and enables monitoring of transceiver operational parameters. The module operates within a 0 to 70°C temperature range, with appropriate thermal considerations for sustained operation in controlled server room environments.

CRITICAL NOTE: CWDM transceivers are wavelength-specific devices. Each module is configured for a specific wavelength channel within the CWDM grid. Ensure proper wavelength coordination when deploying multiple channels over the same fiber infrastructure using CWDM multiplexers and demultiplexers.

Standards compliance includes IEEE 802.3ae for 10 Gigabit Ethernet, ITU-T G.694.2 for CWDM wavelength grid specifications, along with SDH/SONET, Fiber Channel, and OTN support. The transceiver achieves multi-vendor interoperability through adherence to industry MSA standards, though equipment with vendor-specific module validation may require custom EEPROM programming for compatibility. Our 10G SFP+ CWDM transceiver is CE/RoHS certified, and it is compliant with product safety standards.

Typical applications are metropolitan area network aggregation, regional network deployments, point-to-multipoint network architectures, service provider access and distribution networks requiring multiple 10G channels over limited fiber pairs, enterprise campus networks with extended-reach wavelength requirements, and carrier-class infrastructure where CWDM technology enables cost-effective capacity expansion without additional fiber deployment. The multi-rate capability accommodates legacy Gigabit Ethernet operation at 1.25 Gbps alongside native 10 Gigabit rates, providing operational flexibility for mixed-speed network deployments. Because our focus is providing top quality service, we are performing serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanness tests and SFP+ transceiver EEPROM memory data validation tests.
