QSFP-40/100-SRBD, Cisco Dual-Rate 40/100GBASE-SR BiDi QSFP28 Transceiver, Refurbished
Warranty: Lifetime
Quick answer: The Cisco QSFP-40/100-SRBD is a dual-rate 40G/100G QSFP28 BiDi optic that runs over a single pair of multimode fibers with a duplex LC connector: at 100G up to 70 m on OM3 and 100 m on OM4, and at 40G up to 100 m on OM3 and 150 m on OM4. This listing is a genuine Cisco module. Resilient Tec sells it refurbished, with a lifetime warranty and free US shipping from Knoxville, TN.
Condition: Refurbished
Cisco QSFP-40/100-SRBD Dual-Rate 40/100GBASE-SR BiDi QSFP28 Transceiver
Product Description The Cisco QSFP-40/100-SRBD is a dual-rate 40G/100G QSFP28 optical transceiver module featuring Bidirectional (BiDi) technology. It enables cost-effective upgrades from 40G to 100G over existing duplex multimode fiber (MMF) infrastructure with LC connectors, eliminating the need for new parallel fiber cabling. Ideal for short-reach data center interconnects and high-density enterprise networks.
Key Features
- Dual-rate support: 40 Gbps and 100 Gbps operation
- Bidirectional (BiDi) transmission over duplex LC MMF (uses ~850nm and ~900nm wavelengths)
- Reach: Up to 70m (OM3) / 100m (OM4) in 100G mode; 100m (OM3) / 150m (OM4) in 40G mode
- Hot-swappable QSFP28 form factor
- Low power consumption and digital diagnostics monitoring
Compatibility
- Cisco switches and routers with QSFP28 ports (e.g., Nexus 9000, Catalyst 9500 series)
Frequently Asked Questions
Can I reuse my existing duplex LC multimode fiber?
Yes. BiDi sends and receives on the same fiber pair, so it runs 40G or 100G over existing two-fiber LC cabling with no MPO trunks.
What does dual-rate mean?
The same module can run at 40G or 100G, depending on the port. Both ends of a link must be BiDi optics running at the same speed.
Is this an original Cisco part?
Yes, a Cisco-branded QSFP-40/100-SRBD, sold refurbished.
What warranty and shipping come with it?
Resilient Tec's lifetime warranty. US standard shipping is free with no minimum, and orders typically arrive in 3 to 5 days.
