New brochure: optical transceivers



Our product range for optical transceivers expanded in the spring and we’ve now compiled the basic selection to a new brochure.

With these products the optical signal in the fiber optic network can be converted to an electrical signal from 1G transfer rate networks up to 400G high speed data center networks. Options include products for different distances, connectors, operating temperatures, as well as laser transmitter and receiver types.

Data centers often have server and communication racks waiting to be installed. This may, depending on the cooling solution, lead to airflows passing through empty racks, resulting in inefficient cooling and energy efficiency of the data center.


Multifiber MPO/MTP products

Monikuituiset MPO/MTP-tuotteet

MPO/MTP cables (data center standard) have 12 or 24 single fibers in one connector. MPO/MTP is a popular connector for multi-mode fiber optic cabling for 40–400 G data transfer rates. The MPO/MTP connector is the same size as SC connector and the MPO/MTP cable is significantly smaller than a normal patch cord.


LPS (Leak prevention system)

LPS is a patented technology that enables the flow and return water supply within the data center cooling system to be put on a negative water circuit. This allows the system to operate without the fear of leaks or water damage to critical equipment or room infrastructure. 

The LPS is modular and scalable in design and it can be retrofitted to an existing circuit.





Busbars are used to build power distribution assemblies that can be flexibly altered as needed. 

Busbars are used especially in data centers, factories, large high-rise buildings and hospitals with high-power devices, the need to easily change electrical installations or prepare for later expansion.

The idea is, that coolers installed between the racks absorb the heat generated by the servers. Then, the heat energy is transferred to the circulating water, which is routed via pipelines away from the data center.




Devices in server racks need organized, untroubled power distribution. PDU’s are used to supply power for individual devices inside the server rack. Server racks can have multiple power supplies. For example, PDUs on the left side of the rack may receive power from UPS1 system and PDU’s on the right from UPS2 system.


Three reasons to choose rear door cooling in data center


In the early 2000s, two new systems came into the market to cool down the data centers: in-row cooling and rear door cooling. Both aim to bring cooling closer to the heat source so that the solution is as energy efficient as possible. Both methods naturally have their own strengths, and both are in use in the market. The share of rear door coolers is on the rise, so we found out the three most important factors behind the popularity.
