H3C Single-Mode Multi-Mode Optical Module

H3C single-mode optical modules are SFP/SFP+ transceivers designed for long-distance fiber connectivity, typically operating at 1310nm with LC duplex connectors and supporting 1G or 10G data rates.OverviewH3C single-mode optical modules are used to transmit data over single-mode fiber (SMF), which is ideal for long-distance communication due to low signal loss and minimal dispersion . These modules convert electrical signals to optical signals and vice versa, supporting functions such as optical power control, signal monitoring, and decision regeneration . Common form factors include SFP and SFP+, with data rates ranging from 1 Gbps to 10 Gbps for single-mode applications .Key SpecificationsWavelength: 1310nm is standard for single-mode modules, providing optimal performance over long distances .Data Rate: 1G (SFP) and 10G (SFP+) are typical, supporting Gigabit Ethernet and Fibre Channel applications .Transmission Distance:1G SFP modules (e.g., SFP-GE-LX-SM1310-D) support up to 10 km over SMF .10G SFP+ modules (e.g., SFP-XG-LX-SM1310) support 10 km to 20 km depending on fiber quality and network conditions .Connector Type: LC duplex connectors are standard for single-mode modules .Compliance: Modules comply with SFP MSA, IEEE 802.3z/ae, and SFF-8472, ensuring interoperability with H3C switches, routers, and NICs .Deployment ConsiderationsLong-Distance Links: Single-mode modules are suitable for intra-building and inter-building connections, backbone networks, and data center interconnects .Digital Optical Monitoring (DOM): Many H3C modules support DOM/DDM, allowing real-time monitoring of optical power, temperature, and signal integrity .Compatibility: H3C single-mode modules are tested for compatibility with H3C networking devices, ensuring reliable operation and avoiding link failures .Cost-Effective Alternatives: Third-party compatible modules (e.g., OPTCORE SFP-GE-LX-SM1310-A) offer similar performance at lower cost while maintaining H3C compatibility .Popular Models1G Single-Mode: SFP-GE-LX-SM1310-D, SFP-GE-LH40-SM1310-D10G Single-Mode: SFP-XG-LX-SM1310, SFP-XG-LX-SM1310-A/D/EBi-Directional Options: SFP-GE-LX-SM1310-BIDI for 1G, supporting single-fiber links . H3C single-mode optical modules provide reliable, long-distance connectivity for enterprise and data center networks, balancing performance, compatibility, and cost efficiency. Proper selection depends on required data rate, distance, and network infrastructure.
