Cisco Compatible QSFP-100G-B40U4 & QSFP-100G-B40D4
100GBASE BiDi QSFP28 Transceiver Pair | 40km LC Simplex SMF | Upstream & Downstream
Product Overview
The Cisco compatible QSFP-100G-B40U4 and QSFP-100G-B40D4 are a matched pair of high-performance 100GBASE BiDi QSFP28 optical transceivers designed for ultra-long-distance 100 Gigabit Ethernet transmission over a single strand of single-mode fiber (SMF).
Using advanced BiDi (Bidirectional) optical transmission technology, these modules support simultaneous transmit and receive communication over one simplex LC fiber, significantly reducing fiber infrastructure requirements and deployment costs.
The transceiver pair supports transmission distances up to 40 kilometers over standard single-mode fiber, making them ideal for:
- Long-distance data center interconnects (DCI)
- Metro and regional transport networks
- ISP and telecom backbone infrastructure
- Enterprise campus interconnections
- Carrier Ethernet deployments
- Fiber-constrained network environments
- Cloud and edge computing infrastructure
The QSFP-100G-B40U4 operates as the upstream module, while the QSFP-100G-B40D4 operates as the downstream module. Both modules must be deployed together as a matched BiDi optical pair.
Key Features
- Supports 100GBASE BiDi Ethernet
- QSFP28 hot-pluggable form factor
