100G QSFP28 ZR4 BIDI 80KM LC Optical Transceiver

Product Description

100G QSFP28 ZR4 BIDI 80KM Optical Transceiver is a high-performance bidirectional optical module designed for 100G Ethernet long-haul applications. This compact QSFP28 form factor solution enables 100Gb/s transmission over single-mode fiber up to 80km using wavelength division multiplexing (WDM) technology. The BIDI (bidirectional) design allows simultaneous transmission and reception on a single fiber strand, effectively doubling fiber capacity. With low power consumption and digital diagnostics monitoring, it's ideal for data center interconnects, metro networks, and 5G transport systems requiring cost-effective, high-density 100G connectivity. The module complies with industry standards including IEEE 802.3ba and QSFP28 MSA specifications.
