10G CWDM XFP 40km Transceiver: CWDM-10G-XFP-40

Our EDGEOPTIC CWDM-10G-XFP-40 is a multi-vendor compatible 10G CWDM XFP dual-fiber optical module designed for extended-reach wavelength-division multiplexed 10 Gigabit Ethernet applications operating over single-mode fiber cabling. While XFP represents a legacy transceiver form factor approaching end-of-life status in many deployments, this module continues to serve critical infrastructure requiring XFP compatibility. The CWDM-10G-XFP-40 operates across the full CWDM spectrum from 1270nm to 1610nm, supporting all 18 ITU-T G.694.2 CWDM channels with 20nm spacing. Supporting data rates from 1.24 to 11.32 Gbps across multiple protocol standards and applications, each module is configured for specific wavelength operation. Our 10G CWDM XFP transceiver utilizes DFB (Distributed Feedback) laser technology for transmission paired with PIN photodiode for optical reception. The transceiver ensures a 16 dB guaranteed optical link budget, which determines the maximum transmission distance capabilities. Over single-mode fiber, the transceiver reliably reaches distances up to 40 kilometers, enabling cost-effective wavelength-multiplexed connectivity for metropolitan and regional networks. However, distance is just an indicative parameter calculated for convenience of identification – ultimately we calculate distance considering minimal optical budget and average attenuation of optical cabling in the industry.

The CWDM-10G-XFP-40 compatible module features hot-pluggable XFP architecture with duplex LC/UPC connectors as the optical interface. Each transceiver operates on a specific CWDM wavelength channel, requiring proper wavelength planning and passive CWDM multiplexer/demultiplexer infrastructure for system deployment. The electrical interface conforms to INF-8077i XFP MSA Rev.4.5 specifications, ensuring compatibility with legacy XFP host systems supporting multiple vendor equipment platforms. Our 10G CWDM XFP transceiver can be encoded to maintain compatibility and successfully operate across 80+ brands of network equipment. The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time operational data including transmitted and received optical power levels, module temperature, laser bias current, and supply voltage. The module operates within standard 0 to 70°C temperature range, with appropriate thermal management for sustained operation in controlled telecommunications environments.

Standards compliance encompasses IEEE 802.3ae for 10 Gigabit Ethernet, alongside comprehensive SDH/SONET specifications supporting STM-16 through STM-64, and multi-rate Fiber Channel support from 1G to 10G. Additionally, the transceiver supports Optical Transport Network applications including ODU0 through ODU2e and OTU1 through OTU2f standards. The CWDM implementation enables up to 18 separate 10G channels over single fiber infrastructure, dramatically increasing network capacity without additional cable deployment. The transceiver achieves multi-vendor interoperability through strict adherence to industry MSA standards, though equipment implementing vendor-specific module validation may require custom EEPROM programming for seamless compatibility. Our 10G CWDM XFP transceiver maintains CE/RoHS certification and complies with Class 1 FDA and IEC60825-1 laser safety standards.

Typical applications include metropolitan area network infrastructure expansion, regional telecommunications capacity upgrades requiring XFP compatibility with wavelength multiplexing, and existing long-reach systems seeking bandwidth multiplication through CWDM technology. The 40-kilometer reach provides ideal coverage for inter-city connections and distributed campus environments. 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 where XFP form factor remains mandatory. Because our focus centers on providing top quality service, we perform comprehensive quality checks before delivery. Consequently, we conduct optical parameter measurements, connector cleanliness tests, and XFP transceiver EEPROM memory data validation tests for every module.
