10G Tunable DWDM SFP+ 80km C-Band Transceiver: DWDM-10G-SFP-80-TUN

Our EDGEOPTIC DWDM-10G-SFP-80-TUN is a multi-vendor compatible 10G Tunable DWDM SFP+ dual-fiber optical module engineered for long-haul dense wavelength division multiplexing 10 Gigabit Ethernet applications with software-configurable wavelength selection over single-mode fiber infrastructure. The DWDM-10G-SFP-80-TUN module operates across ITU-T C-Band channels 17 through 61 on the 50 GHz DWDM grid, supporting 89 channels with data rates from 1.25 to 11.32 Gbps across multiple protocol standards and network applications. Our 10G Tunable DWDM SFP+ transceiver utilizes Monolithic MZM (Mach-Zehnder Modulator) Tunable TOSA technology for transmission and APD (Avalanche Photodiode) for signal reception. The transceiver ensures a 23 dB guaranteed optical link budget, which determines the maximum transmission distance capabilities. Over single-mode fiber (SMF), the transceiver can reach distances up to 80 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.

DWDM-10G-SFP-80-TUN compatible 10G Tunable DWDM 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 Tunable DWDM 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: Tunable DWDM transceivers offer wavelength flexibility through software-configurable channel selection across the ITU-T DWDM grid. This module supports 89 channels on the 50 GHz C-Band grid, providing on-demand wavelength provisioning that dramatically simplifies inventory management and reduces operational complexity. Ensure proper wavelength coordination and thermal management when deploying multiple channels over the same fiber infrastructure using DWDM multiplexers and demultiplexers. DWDM systems require careful planning and precise wavelength control.

Standards compliance includes IEEE 802.3ae for 10 Gigabit Ethernet, ITU-T G.694.1 for DWDM 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+ Tunable DWDM transceiver is CE/RoHS certified, and it is compliant with product safety standards.

Typical applications are long-haul metropolitan area networks, regional network backbones, carrier-class telecommunications infrastructure requiring wavelength flexibility, inter-city data center interconnects with dynamic channel provisioning needs, service provider distribution networks with extended-reach requirements, and wide area networks where tunable DWDM technology enables cost-effective massive capacity expansion with superior spectral efficiency, simplified inventory management, and rapid service deployment without additional fiber infrastructure. 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.
