10G CWDM SFP 80km Optical Transceiver: Telecom Enterprise Long-Haul Transmission Solution
The 10G CWDM SFP 80km optical transceiver is a compact transceiver device specifically designed for long-haul transmission needs in telecom enterprise applications. Utilizing Coarse Wavelength Division Multiplexing (CWDM) technology, it enables stable transmission of multi-channel 10Gbps signals over 80 kilometers on single-mode fiber. This category of telecom-grade optical modules complies with the SFP+ Multi-Source Agreement (MSA) standard and supports 18 CWDM wavelength channels as specified in ITU-T G.694.2, making it a critical optical component for constructing metropolitan access networks and enterprise private lines.
In terms of technical performance, this module offers three core advantages: First, it employs a low-chirp EML laser combined with an APD receiver, achieving a receiver sensitivity of -28dBm in the 1550nm band with a power budget exceeding 30dB. Second, it integrates Digital Diagnostic Monitoring (DDM) functionality, enabling real-time monitoring of 14 parameters including temperature, bias current, and received power, complying with the SFF-8472 protocol. Third, its operating temperature range covers industrial-grade standards (-40°C to 85°C), maintaining stable performance in 85% humidity environments, meeting the stringent requirements of telecom equipment.
This type of long-haul transmission optical module is widely used in scenarios such as 5G fronthaul networks, enterprise data center interconnects, and smart city private networks. Actual deployment data shows its bit error rate is better than 10⁻¹², with a power penalty of less than 2dB over 80km transmission distance and channel isolation exceeding 30dB. Compared to standard 10km SFP+ modules, the 80km version features unique dispersion compensation design, effectively suppressing inter-symbol interference in long-distance transmission, making it a cost-effective choice for building metropolitan optical networks.
With the large-scale deployment of 5G networks, new-generation intelligent CWDM SFP+ modules are beginning to integrate wavelength tunability and power adaptive functions. Through coordinated control between built-in micro-MEMS tuners and network management systems, remote dynamic wavelength configuration and intelligent optimization of link quality can be achieved. In future-oriented Software-Defined Optical Network (SDON) architectures, these modules are driving the evolution of the optical transmission layer towards flexibility and programmability.
