The singlemode, 2 km range, duplex LC connector module is excellently suited for data centers, enterprise backbone networks, campuses, and service provider infrastructures.
Main features
- 100 Gb/s data transmission speed in QSFP28 format
- Designed for singlemode optical fiber
- Up to 2 km range
- Duplex LC optical connector
- Low power consumption, high reliability
- Full compatibility with QSFP28 ports and 100G Ethernet standards
Reliable 100G connection over long distances
The module provides a high-bandwidth connection over singlemode optical fiber for distances of up to 2 km. This is an ideal solution for connections between data centers, backbone networks between buildings, and main connections in larger campus networks where a stable and fast 100G connection is required.
The duplex LC connector allows for simple, standard connections to existing optical infrastructures, making network expansion cost-effective and quick.
QSFP28 module – high-density and flexible solution
The QSFP28 module format allows for high port density on network devices, enabling multiple 100G connections to be established in the same space. This is particularly important for modern switches and routers, where optimizing rack space and power consumption is a priority.
The module is compatible with standard 100G Ethernet protocols, making it easy to integrate into existing network devices, whether in a data center spine-leaf architecture, core switch interconnections, or building an aggregation layer.
Applications
- 100G optical uplink connections between data centers
- Connections between enterprise backbone networks and core switches
- 100G lines for service provider networks (ISP, telecommunications providers)
- Building the main optical backbone of campus networks
- High-bandwidth connections in cloud and virtualization environments
Benefits for network operators
- High bandwidth – The 100 Gb/s data transmission capacity ensures that the network can serve increased data traffic in the long term, such as in virtualization, cloud services, large-volume data backups, and replications.
- Stable, reliable operation – The singlemode optical technology and carefully designed modular structure result in minimal error rates and low latency, which are crucial for critical services.
- Easy installation – The module supports hot-swap (live replacement), allowing it to be replaced or expanded without shutting down the network device. With the standard duplex LC connector, installation is quick and straightforward.
- Cost-effective expansion – The QSFP28 module allows existing infrastructure to be prepared for 100G speeds without the need for a complete equipment replacement. This reduces capital costs and provides faster returns on investment.
Compatibility and standards
The module complies with relevant QSFP28 and 100G Ethernet standards, making it widely compatible with various manufacturers' switches, routers, and other network devices. It is an ideal choice for systems where multi-vendor environments and easy interchangeability are important.
Thanks to standard operation, it can be easily integrated into existing network solutions where 40G or 25G modules are already in use, and the network is gradually transitioning to 100G speeds.
Energy efficiency and reliability
The module's low power consumption reduces operating costs and mitigates heat generation in rack cabinets. This is particularly important in high port-density environments where many 100G modules operate simultaneously.
The robust design and quality components ensure long-term, continuous operation, which is essential in 24/7 data centers and critical business systems.
