Our QSFP28 Bidirectional (Bidi) transceivers delivers high-speed 100G connectivity over a single strand of fiber, with reach options up to 70km and support for both standard and industrial temperature environments. Designed for service providers, data center operators, and access networks, our Bidi. By employing two different wavelengths (850nm and 900nm) on the same fiber strand, it achieves 100mbps full-duplex communication over distances up to 100 meters on OM4 fiber. ZR4 BiDi, using four. Our 100G BiDi QSFP28 SR1. Supporting 150m over OM5 multimode fiber at 850/900nm wavelengths, this module delivers 1. 25 Gbps using single-lambda PAM4. This QSFP28 utilizes 1270nmTX/1310nmRX,1309nmTX/1304nmRX wavelength and simplex LC connector.
