In the relentless pursuit of higher bandwidth, data center and network operators face a constant challenge: their existing fiber cabling infrastructure. Pulling new fiber is notoriously expensive, time-consuming, and disruptive. So, what's the solution when you need to jump from 40G or 10G to 100G but are staring at a congested fiber duct? Enter the unsung hero of network upgrades—the QSFP28 100G BiDi transceiver.
This clever piece of technology is a game-changer for maximizing the value of your current fiber plant. Let's explore how it works and why it should be a key part of your high-speed network strategy.
➤ Key Takeaways
QSFP28 100G BIDI modules send and get 100G data with one fiber pair. This saves space and lowers cable costs.
These modules fit into normal QSFP28 ports. They use simplex LC connectors. You can install them quickly by just plugging them in.
BIDI technology makes networks faster and more stable. It also uses less power, so it is great for data centers.
QSFP28 modules are small and save rack space. You can upgrade easily without needing more equipment.
QSFP28 100G BIDI modules work with multi-mode and single-mode fiber. This gives you more choices for different network setups.
➤ What is a QSFP28 100G BiDi Transceiver?
Unlike standard 100G QSFP28 transceivers that use two fibers (one for transmit, one for receive), a Bidirectional (BiDi) transceiver uses only one single fiber strand for both transmitting and receiving data. It achieves this optical magic by using two different wavelengths (colors of light) on the same fiber.
A typical 100G BiDi module will use one wavelength (e.g., 1271nm) to transmit data and another (e.g., 1331nm) to receive data. This allows a full duplex 100G connection to be established over a single fiber strand, effectively doubling the capacity of your existing fiber links.
➤ Key Advantages of Deploying 100G BiDi Optics
Why should you consider BiDi for your next 100G deployment?
Maximizes Existing Fiber Infrastructure: This is the biggest benefit. If you are running out of fiber conduits, BiDi instantly doubles your available capacity. You can support a 100G link on a single fiber pair where you once only supported 10G or 40G.
Cost-Effective: While the transceivers themselves might be slightly more expensive than their duplex counterparts, the massive savings from avoiding new fiber trenching and installation make the total cost of ownership significantly lower.
Reduced Complexity: Less fiber spaghetti in your trays means a cleaner, more manageable patch panel and reduced physical layer complexity.
Faster Deployment: Upgrading becomes a simple matter of swapping transceivers at each end of the link, not a weeks-long construction project.

➤ FAQ
What makes 100g qsfp28 bidi modules different from standard sfp modules?
100g qsfp28 bidi modules use bidi technology to send and get data on one fiber pair. Standard sfp modules often need more fibers to work. These modules help network teams save space in racks. They also lower cabling costs in data centers.
Can 100g qsfp28 bidi modules work with both multi-mode and single-mode fiber?
Yes, 100g qsfp28 bidi modules work with both multi-mode and single-mode fiber. This means network engineers can use them in many network setups. The modules fit into normal qsfp28 slots.
How do bidi sfp modules help with network upgrades?
Bidi sfp modules make upgrades easy for network teams. They use simplex LC connectors and need fewer cables. Teams can add 100g links without changing all the cables. The modules support plug-and-play for quick setup.
What should engineers consider when selecting the appropriate qsfp28 transceiver?
Engineers should check if the modules support 100g speeds and bidi transmission. They should also see if the modules work with current network equipment. Picking the right qsfp28 transceiver helps the modules work with sfp slots and fiber types.
Are 100g qsfp28 modules energy efficient for large networks?
100g qsfp28 modules use less power than old sfp modules. This helps lower energy costs in big networks. The modules also keep racks cool and support fast data needs.
Tip: Picking the right qsfp28 transceiver helps networks stay fast and strong as they grow.
