This BiDirectional (BDSR) optical module transmits 40Gbps over a single pair of standard multimode fiber via a Duplex LC interface. Eliminating the need for expensive MPO cable upgrades, it provides an instant, plug-and-play 10G-to-40G migration path for distances up to 100m or 150m. Enter the 40/100G SWDM4 module, a game-changing solution that combines dual-rate compatibility with the efficiency of Short Wavelength Division Multiplexing (SWDM) technology. This compact yet powerful module offers a wealth of benefits, from increased bandwidth capacity to cost-effective. WolonFiber manufactures strictly MSA-compliant 40G QSFP+, 50G SFP56, and 50G QSFP28 optical interconnects optimized for mission-critical telecommunications and campus deployments. This module, designed in a parallel Quad Small Form-factor Pluggable (QSFP28) Bi-Directional format, efficiently integrates four host electrical data streams into two optical. The QSFP transceiver modules (Quad Small Form-factor Pluggable) represent a versatile and high-density family of optical transceivers. They are specifically engineered for high-performance data communication applications. In addition to its native 100G capability, QSFP28 also offers.
