## Summary description

The BlueOptics NK0J8-BO is a QSFP28 fiber optic transceiver module designed for high-speed data transmission over distances up to 2000 meters. It features an aluminum casing, weighs 40 grams, and is packaged as a single unit. Ideal for network applications requiring reliable and efficient connectivity.

## Long description

The BlueOptics NK0J8-BO QSFP28 2000m is a fiber optic transceiver module designed for high-speed single‑mode optical links up to 2,000 meters. The module uses a QSFP28 interface with LC duplex optical connections and an aluminium housing. It supports 100G optical transmission and is supplied as a single unit with a compact form factor and a weight of approximately 40 g.
Advantages
This QSFP28 module is compatible with MSA‑compliant QSFP28 interfaces and follows 100GBASE‑CWDM4 transmission characteristics, enabling reliable 100 Gbps links over single‑mode fiber. The aluminium casing provides mechanical protection and thermal dissipation while the compact, lightweight design simplifies installation in switches, routers and other network equipment. The module supports digital diagnostic monitoring (DDM/DOM) for real‑time status of supply voltage, laser bias, transmit power, received power and temperature when used in hardware that exposes these diagnostics.
Suitable for
High‑capacity Ethernet interconnects in data centers and aggregation sites
Connections between switches, routers and optical patch panels up to 2 km
100G optical links for carrier, enterprise and storage network environments
Key specifications
Interface type: QSFP28
Protocol support: 100G (100GBASE‑CWDM4 compatible operation)
Optical fiber type: Single‑mode fiber
Connector: LC duplex
Maximum transmission distance: up to 2000 m
Housing material and colour: aluminium (aluminium colour)
Weight: approx. 0.04 kg
Form factor: QSFP28 small form factor
How to use
Install the QSFP28 transceiver into a compatible QSFP28 port on supported network equipment following the equipment manufacturer’s insertion and hot‑swap guidelines. Connect LC duplex single‑mode fiber patch cords to the transceiver’s optical ports, taking care to match transmit and receive fibers correctly. Verify link status via the host device interface; if supported, access DDM/DOM data to monitor voltage, laser bias, transmit and receive power and module temperature for remote diagnostics. Ensure device firmware and port settings match the 100GBASE‑CWDM4 operating mode when required.
Usage recommendations
Use high‑quality single‑mode LC duplex fiber patch cords and appropriate cable management to maintain signal integrity. Confirm compatibility with the target hardware and enable DDM/DOM support in the host device to facilitate monitoring and troubleshooting. Avoid exposing the module to extreme temperatures or mechanical stress during installation.
