What makes this 100G QSFP28 optical transceiver suitable for 20km distances compared to standard CWDM4 modules?

Unlike CWDM4 modules which are typically limited to 2km, this 100G QSFP28 optical transceiver utilizes narrow-band LAN-WDM technology and a powerful EML laser, significantly minimizing chromatic dispersion to reliably support 20km single-mode fiber links.

Does this 100G QSFP28 optical transceiver require Forward Error Correction (FEC) to achieve the full 20km reach?

Yes, to ensure zero bit error rates and optimal signal integrity over the maximum 20km distance, it is required to enable host-side RS-FEC when deploying this 100G QSFP28 optical transceiver.

Can I deploy this commercial-grade 100G QSFP28 optical transceiver in an outdoor telecom cabinet?

This specific 100G QSFP28 optical transceiver is designed for commercial temperature ranges of 0 to 70 degrees Celsius; for unconditioned outdoor cabinets subject to extreme weather, an industrial-grade variant would be required.

Is this 100G QSFP28 optical transceiver compatible with optical transport network (OTN) equipment?

Yes, this 100G QSFP28 optical transceiver complies with IEEE 802.3ba standards and can be seamlessly integrated into compatible OTN client-side interfaces requiring reliable extended reach connectivity.

How does the DDM feature of this 100G QSFP28 optical transceiver improve network maintenance?

The Digital Diagnostics Monitoring in this 100G QSFP28 optical transceiver allows network engineers to monitor optical power and module temperature in real-time, enabling proactive troubleshooting before potential fiber link failures occur.

We plan to install these in unventilated outdoor edge cabinets. Do you have an industrial wide-temperature version of this 100G optic?

This specific module is designed for standard commercial operating temperatures (0°C to 70°C). However, we do offer an industrial-grade version (-40°C to 85°C) for this exact 1310nm 20km spec. Please check our store or contact support directly for the industrial SKU.

We are rolling out a regional ISP upgrade and need about 50 of these 100G LAN-WDM modules. Do you offer bulk discounts?

Absolutely! For large-scale B2B procurements of our 100G QSFP28 20km transceivers, please contact our B2B sales team. We provide tiered volume pricing and dedicated procurement support for enterprise and ISP clients.

Can I use multimode fiber (OM4) for a short 50m run in the server room, or is this strictly for single-mode?

This LAN-WDM transceiver is designed exclusively for Single Mode Fiber (SMF) with a Duplex LC connector. To prevent receiver saturation and signal distortion on short runs, we strongly recommend using OS2 SMF cable along with appropriate optical attenuators for very short distances.

Does this optic support OTU4 protocols for our telecom optical transport network, or just standard 100G Ethernet?

It is highly versatile. Besides being fully compliant with 100GBASE Ethernet standards, it supports standard OTN OTU4 data rates, making it perfect for both enterprise data center interconnects (DCI) and telecom transport network applications.

Will this 100G QSFP28 20km module work with our mix of Cisco Nexus and Arista datacenter switches?

Yes, these transceivers are strictly tested for OEM compatibility. They will plug and play seamlessly with Cisco, Arista, Juniper, Ubiquiti, and other major switch brands right out of the box without any vendor lock-in issues.
