BlueOptics QSFP28 BiDi lähetin-vastaanotin 100GBASE-ER1-BX-D 40km

High-density data centers often struggle to balance the demand for 100G connectivity with the scarcity of fiber infrastructure. Running new fiber pairs is costly and disruptive, yet single-fiber solutions frequently sacrifice reach or reliability. The BlueOptics QSFP28 BiDi transceiver resolves this tension by delivering full 100G throughput over a single strand of single-mode fiber up to 40 kilometers, effectively doubling the capacity of existing fiber plants without compromising performance.

Who is it for

This transceiver is built for network architects, data center operators, and service providers who need to maximize 100G link density while minimizing fiber usage. It is particularly valuable in campus and metro networks where dark fiber is limited, as well as in enterprise backbones that require long-reach connectivity between facilities. Any organization looking to defer or avoid costly fiber trenching will find this BiDi module an economical and practical choice.

Tips

When deploying BiDi transceivers, always pair this 1330/1270 nm module with its opposite counterpart (1270/1330 nm) on the far end to ensure proper wavelength matching. Use OS2 single-mode fiber with LC simplex connectors and verify link budget to account for splices and patch panels. Enable digital diagnostics on your switch to monitor temperature, voltage, and optical power for proactive maintenance.
