🚀 Upgrade to 100G Without Changing Fiber | Cisco QSFP-40/100G-SRBD=

Dual-Rate 40G/100G BiDi Solution Over Existing LC Fiber

The Cisco QSFP-40/100G-SRBD= is an advanced dual-rate 40G/100G BiDi QSFP28 optical transceiver designed to deliver high-speed connectivity over duplex multimode fiber (LC).

Unlike traditional SR4 modules that require MPO cabling, this BiDi module enables 40G or 100G transmission over existing LC fiber infrastructure, making it the ideal solution for cost-efficient network upgrades.

Built by Cisco Systems, it ensures reliable performance and seamless integration in modern data center environments.

🔥 Why This Product Converts Extremely Well

✔ Want to upgrade from 10G / 40G → 100G? ✔ Don’t want to replace existing LC cabling? ✔ Need a fast, low-cost migration path?

👉 This module solves the biggest barrier to 100G: cabling cost

⚡ SR4 vs BiDi (Critical Buying Decision)

Feature	SR4 (Traditional)	SRBD (BiDi)
Fiber	MPO (8/12-core)	LC Duplex (2-core)
Cabling Cost	High	Low
Deployment	Complex	Simple
Upgrade Scenario	New DC build	Existing DC upgrade

👉 If your customer already uses LC → SRBD is the best choice
