40G - 50G Transceivers

40G to 56G optical transceivers are high-speed, hot-swappable modules designed to support increasing bandwidth demands in data centers, telecom networks, industrial systems, and high-performance computing environments. These transceivers enable scalable network upgrades by delivering higher data rates while maintaining compact form factors and interoperability with modern switching and routing platforms. All modules are compliant with applicable Multi-Source Agreement (MSA) specifications and meet CE, FCC, and RoHS requirements. Digital Optical Monitoring (DOM/DDM), where supported, provides real-time insight into operating conditions and optical performance.

 

NAFO/Coretek offers a focused portfolio of 40G to 56G transceivers including:

 

• 40G QSFP+

• 50G SFP56

• 50G QSFP28

• 56G QSFP+

 

These transceivers support a variety of fiber and copper interfaces depending on application requirements. 40G QSFP+ modules are widely used in data center aggregation and core networks and are available in short-reach and long-reach variants over multimode and single-mode fiber. 50G SFP56 and 50G QSFP28 modules support next-generation 50 Gigabit Ethernet architectures, offering improved signal efficiency and reduced power consumption compared to earlier generations. 56G QSFP+ transceivers are commonly deployed in InfiniBand and high-performance computing environments, delivering high-throughput, low-latency connectivity.

 

Transmission distances vary by form factor and optical variant, ranging from short-reach links such as 70 m, 100 m, and 150 m over multimode fiber to longer single-mode fiber distances including 2 km, 10 km, 40km, and 80km. Available interface options include MPO and LC connectors, as well as direct-attach copper (DAC) and active optical cable (AOC) solutions where applicable.
