Cisco Compatible QSFP-100G-B80U4 & QSFP-100G-B80D4
100GBASE BiDi QSFP28 Transceiver Pair | 80km LC Simplex SMF | Upstream & Downstream
Product Overview
The Cisco compatible QSFP-100G-B80U4 and QSFP-100G-B80D4 are a matched pair of ultra-long-reach 100GBASE BiDi QSFP28 optical transceivers designed for 100 Gigabit Ethernet transmission over a single strand of single-mode fiber (SMF).
Utilizing advanced BiDi (Bidirectional) optical transmission technology, these modules support simultaneous transmit and receive communication through one simplex LC fiber, significantly reducing fiber infrastructure requirements and deployment costs for long-distance optical networks.
The transceiver pair supports transmission distances up to 80 kilometers over standard single-mode fiber, making them ideal for:
- Carrier and telecom backbone networks
- Metro and regional optical transport
- Long-distance data center interconnects (DCI)
- ISP core infrastructure
- Enterprise WAN connectivity
- Fiber-constrained network environments
- Cloud and edge computing infrastructure
The QSFP-100G-B80U4 functions as the upstream module, while the QSFP-100G-B80D4 functions as the downstream module. Both modules must be used together as a matched BiDi transceiver pair.
Key Features
