BlueOptics QSFP-100G-B40U4-I QSFP28 100G BiDi Transceiver, LC-Simplex, 100GBASE-BX-U, SMF, TX1304.58nm/RX1309.14nm, 40km, compatível com Cisco

BlueOptics QSFP-100G-B40U4-I stands apart from standard 100G optics by using a single strand of single-mode fibre for both transmit and receive paths, effectively doubling the capacity of existing fibre infrastructure. This Cisco-compatible QSFP28 BiDi transceiver operates on the 100GBASE-BX-U standard, transmitting at 1304.58 nm and receiving at 1309.14 nm over distances up to 40 km. It is the practical choice for long-haul links where fibre availability is limited and performance cannot be compromised.

Highlights

• QSFP28 form factor with LC simplex connector for single-fibre operation
• 100 Gbps data rate over 40 km on OS2 single-mode fibre
• Bi-directional design with separate TX and RX wavelengths (1304.58 nm / 1309.14 nm)
• Digital diagnostics monitoring (DDM/DOM) for real-time link health
• Hot-pluggable and MSA compliant for seamless integration
• Commercial temperature range (0°C to 70°C) for standard data centre environments

In daily use

Deploying this transceiver means fewer fibre pairs to manage and lower cabling costs, especially in metro and campus networks. The integrated DDM provides visibility into optical power, temperature, and voltage, enabling proactive maintenance. Because it is coded for Cisco platforms, it works immediately in switches and routers that accept QSFP-100G-B40U4-I optics, without the need for configuration changes. The robust metal housing and latch mechanism ensure reliable connections in high-density racks.
