BlueOptics QSFP-100G-SR4-S-BO — Cisco-Compatible 100G SR4
The BlueOptics QSFP-100G-SR4-S-BO is a 100 Gbit QSFP28 transceiver of the SR4 type: four 850 nm lanes over an MPO multimode trunk, up to 100 m on OM4, with digital diagnostics. It is programmed as a Cisco QSFP-100G-SR4-S, so Cisco Nexus and Catalyst switches that check optics accept it, and it is made by CBO in Germany as an alternative to the original part. In practice, multimode optics are the cheaper choice for links inside one building: most server rooms and floor risers already carry OM3 or OM4 fibre, and the module plus a short patch cord is all a port needs. Before you order, check the fibre grade printed on the cable jacket and the real length of the run, including patch panels.
