Unlocking 100G Connectivity—Extend & Optimise Networks with QSFP28 100G ZR4 Transceivers

In today’s fast-evolving network environments, service providers and enterprise operators are pushing existing hardware further—demanding more capacity, speed, and reach from their infrastructure. For many, the challenge has been clear: how to deliver cost-effective 100G services beyond the traditional 40km limit from low-cost QSFP28 ports without expensive open-line systems or bulky hardware upgrades.

MSA and TAA Compliant 100GBase-ZR4 QSFP28 Transceiver (SMF, 1295nm to 1309nm, 80km, LC, DOM)	SKU: QSFP28-100GB-ZR4-C

Revolutionising Distance: The QSFP28 100G ZR4 Solution

ProLabs has responded with a leap in fiber reach technology: the QSFP28 100G ZR4 transceiver family. Marrying cutting-edge Avalanche Photo Diode (APD) receivers with Semiconductor Optical Amplifier (SOA) technology, this line offers robust 100G Ethernet connectivity over single-mode fiber—now up to an astonishing 80km—without reliance on costly amplification equipment or external DWDM devices

Why ZR4 Transceivers Change the Game

Stretch 100G signals up to 80km using affordable QSFP28 optics.
Bypass expensive open-line systems, reducing both upfront and ongoing costs.
Accelerate deployments—ZR4 optics work seamlessly with existing QSFP28 ports in routers and switches.
Ensure compatibility across the spectrum of leading OEM network equipment.

Reimagine Your Backbone & Service Distribution

Deploying ZR4 transceivers means leveraging your current QSFP28 investments to deliver new 100G services further and faster.

This is especially beneficial for:

Metro and regional networks seeking to expand high-speed reach without drastic capital outlay.
Mobile and wireless backhaul extensions, where fibre upgrades are costly and time-consuming.
Service providers who need rapid flexibility without the burden of managing hybrid optical networks.

By eradicating the 40km limitation, network architects can now interconnect sites, core, and edge locations with high-speed 100G links—directly, efficiently, and at a fraction of historical deployment costs.

Key Benefits

Cost efficiencies—lower TCO versus legacy DWDM/open-line alternatives.
Simple deployment—plug-and-play integration with a vast array of OEM switches and routers.
Technical assurance—ProLabs provides expert support for specification, diagnosis, and troubleshooting at every stage.

Ready to Extend Your 100G Network?

The QSFP28 100G ZR4 sets a new standard for speed and distance—delivering high-performance optical links that scale as you grow, without the usual barriers. Network transformation doesn’t have to mean forklift upgrades. Instead, deploy smarter optics and radically reimagine what’s possible on your existing fibre plant.
