New SRD 5 - Program optical modules from your smartphone.

The device is designed to reconfigure optical modules to work with most network devices on the market. This latest version substantially enhances the functionalities of its predecessors, offering users the potential to save up to $300,000 annually, alongside the convenience of smartphone-based configuration. 

The SRD 5 introduces the ability to program advanced interfaces such as OSFP (400G/800G/1.6T), QSFP-DD (400G/800G) and SFP-DD (100G) to create universal optical transceivers. It also allows the configuration of DWDM channels for tunable plugs. The device is supported by a private cloud with a continuously updated compatibility database. There are currently more than 23,000 records and the number continues to grow. 


The SRD 5 also supports the ability to encode modules supported in earlier versions of the SRD: QSFP28(100G), QSFP+(40G), SFP28(25G), SFP+(10G), SFP(1G). 


“Spending on optical modules and their replacement is a significant part of the network construction and maintenance budget,” explained Marcin Bala, CEO of Salumanus. “Most operators, ISPs and data centre owners use equipment from different vendors. This creates the need to maintain a large inventory of spare parts. 


“Universal optical transceiver reduce the need to stock modules. They can be recoded multiple times, adapting configurations to the current needs of the network. With SRD 5, an engineer can programme a universal module from a smartphone directly before installation.” 


The new device works with a variety of platforms, from desktop PCs to smartphones, providing flexibility and accessibility in any environment. With a variety of engineering environments in mind, the SRD 5 offers a wide range of power options, from traditional power supplies to power banks to USB-C power.  


This approach ensures uninterrupted operation even in locations with limited access to power sources. By dispensing with sockets for legacy interfaces, it has also been possible to significantly reduce the size of the device. 


Its compact form factor makes it an ideal tool for field work, allowing engineers to intervene and respond quickly to network issues. The SRD 5 also offers built-in Bluetooth, which enables operation on iOS and Android smartphones, via the SRD Go app.  


“We want the SRD 5 to help the network engineer with compatibility selection and configuration,” said Michał Owca, product manager at Salumanus. “Thanks to this device, it will be possible to check the status of modules, their performance and detect possible errors.”   


Salumanus engineers have calculated that, when operating network equipment from three different vendors, in six network areas, the use of the SRD 5 can save more than 300,000 US dollars per year. Customers will also be able to calculate their saving capacity with the SRD 5 due to a new tool which will be featured on Salumanus’ website.  


The SRD 5, together with Salumanus' universal optical transceivers, reduces costs and the amount of inventory required. In the event of failure, one module can be quickly adapted to different brands of network devices. In this way, the number of spare parts can be significantly reduced, thereby influencing production and raw material consumption, while keeping fault safety at a very high level.
