Optical Modules Compatible with H3C Switches

H3C switches support a wide range of optical modules including SFP, SFP+, SFP28, QSFP+, QSFP28, QSFP56, QSFP-DD, CFP, CFP2, and CXP, covering data rates from 100 Mbps to 400 Gbps for both short- and long-range fiber connections.Supported Optical Module TypesH3C devices are compatible with various transceivers and optical modules, which are hot-swappable and designed for optical-to-electrical and electrical-to-optical conversions. Common form factors include SFP, SFP+, SFP28, QSFP+, QSFP28, QSFP56, QSFP-DD, CFP, CFP2, and CXP. These modules provide functions such as optical power control, signal modulation, IV conversion, and TX-disable, ensuring reliable data transmission over fiber networks .Data Rates and Transmission DistancesH3C optical modules support a wide range of data rates: 100 Mbps, 155 Mbps, 622 Mbps, 1 Gbps, 2 Gbps, 2.5 Gbps, 4 Gbps, 8 Gbps, 10 Gbps, 16 Gbps, 25 Gbps, 32 Gbps, 40 Gbps, 50 Gbps, 100 Gbps, 200 Gbps, and 400 Gbps . Transmission distances are categorized as short-range (≤2 km) and long-range (up to 10 km or more), depending on fiber type, wavelength, and module specifications . For example, the H3C SFP GE SX MM850 A operates at 850 nm over multimode fiber for distances up to 550 m, while single-mode modules like SFP-GE-LX-SM1310 can reach distances from 5 km to 160 km depending on wavelength and fiber type .WavelengthsCommon central wavelengths for H3C optical modules include 850 nm, 1310 nm, and 1550 nm, corresponding to different fiber types and transmission distances. Modules using CWDM or DWDM technologies, such as QSFP-100G-LX4, support multiple wavelengths (1271/1291/1311/1331 nm) for high-speed data center interconnects .Third-Party CompatibilityMany third-party optical modules are fully compatible with H3C switches. Vendors like NADDOD and Fiberinthebox provide modules certified for H3C interoperability, including QSFP-100G-LX4, SFP+, and SFP28 modules, allowing seamless integration with H3C OEM transceivers while offering cost-effective alternatives .Selection ConsiderationsWhen choosing optical modules for H3C switches, consider:Form factor: Ensure the module fits the switch port (SFP, QSFP, CFP, etc.)Data rate: Match the module speed with network requirements (1G, 10G, 25G, 100G, etc.)Fiber type: Multimode (MMF) for short distances, single-mode (SMF) for long distancesWavelength: 850 nm for MMF, 1310/1550 nm for SMFTransmission distance: Based on network topology and fiber loss/dispersionVendor compatibility: OEM or certified third-party modules for guaranteed interoperability By selecting modules according to these criteria, network administrators can ensure stable, high-performance optical connectivity across H3C switches and multi-vendor environments .
