Need help choosing 100G BiDi optical transceivers?
100G BiDi optical transceivers are often used when network teams want to increase bandwidth while making better use of existing fiber resources. Before ordering, reach, fiber type, connector, pairing and device compatibility should be reviewed.
What should be checked before ordering?
100G BiDi is not always a simple one-to-one replacement. The details below help us check whether it fits your link design, platform and deployment environment.
Fiber Type
Single mode, multimode, OM3, OM4, OS2 and existing cabling condition.
Required Reach
100m, 300m, 500m, 2km, 10km, 20km, 40km, 80km or project distance.
Connector Type
LC duplex, MPO/MTP or existing patch cable arrangement.
Device Model
Switch, router, NIC, brand platform and coding requirement.
When should I choose 100G BiDi?
| Situation | Is 100G BiDi suitable? | Next Step |
|---|---|---|
| Existing fiber resources are limited | Often suitable | Confirm fiber type, distance and connector |
| Need to increase bandwidth without major cabling changes | Common use case | Share current link design or BOM |
| New fiber deployment is available | Depends on project design | Compare BiDi with LR4, CWDM4, PSM4 or SR4 |
| Long-distance 100G project link | Needs careful review | Check optical budget, wavelength pair and platform compatibility |
Common 100G BiDi distance options
| Reach | Typical Application | What to Confirm |
|---|---|---|
| 100m / 300m | Data center or enterprise short links | Fiber type, connector and platform compatibility |
| 500m / 2km | Campus or aggregation links | Optical budget, link distance and fiber condition |
| 10km / 20km | Metro access or ISP network links | Wavelength pairing, coding and link budget |
| 40km / 80km | Long-reach project or regional connection | Power budget, temperature grade and deployment risk |
Note: Actual availability depends on fiber type, platform, module design and specific project requirements.
Common 100G BiDi applications
| Application | Typical Need | What We Review |
|---|---|---|
| Fiber-limited upgrade | Increase bandwidth without major cabling changes | Fiber type, reach, connector and link budget |
| Data center connection | 100G links between switches, routers or servers | Form factor, distance and platform coding |
| OEM replacement | Alternative to branded 100G BiDi optics | OEM part number, compatibility and sample plan |

Frequently asked questions
What is a 100G BiDi optical transceiver?
A 100G BiDi optical transceiver is a 100G module designed for bidirectional transmission in selected fiber environments. Exact design and application depend on the specific module type.
When should I choose 100G BiDi?
100G BiDi is often considered when existing fiber resources are limited or when a project needs a practical upgrade path with less cabling change.
Does 100G BiDi require matched pairs?
Some BiDi solutions require matched wavelength pairs. We recommend checking the part number and link design before ordering.
Can 100G BiDi work with Cisco, Arista, Juniper or HPE switches?
Compatibility depends on the device model, firmware and coding requirement. Please share the platform model for review.
Can I start with samples?
Yes. For higher-value 100G optics, sample-first verification is often recommended before batch deployment.
