DWDM Optimization Made Easy Than Ever
No one has such a solution yet. Only at Salumanus we offer an optical module with which you can build an extremely efficient IPoDWDM system in your existing networks. No additional amplifiers and no loss of signal quality.
400G ZR+ 0dBm GBC Photonics is currently one of the most technologically advanced modules available on the market. What is its advantage due to? The module has low power consumption, excellent signal-to-noise ratio OSNR and most importantly — emits a signal with a power of 0dBm! Its parameters were achieved due to the integration of several hitherto separate elements into a single semiconductor assembly. It is built with a tunable laser, modulator, receiver diode and a set of amplifiers designed and built in to achieve maximum output quality. The described transceiver system was created based on InP — indium phosphate technology.
Parameter power 0dBm
Most of the existing networks are prepared to operate with a signal with a power not lower than -2 dBm. A power of 0dBm must hit the multiplexer. Meanwhile, the 400G ZR+ modules available so far emitted a -10 dBm signal, which forced the use of additional amplifiers in the DWDM system, which significantly reduced the signal quality and often forced additional adjustment of the entire system. Manufacturers of modules competing with GBC Photonics address this problem by adding a miniature EDFA amplifier to the -10dBm transmitting module. At the expense of additional power consumption and significantly worse OSNR parameter of the transmitter.
GBC Photonics 400G ZR+ 0dBm GBC module can be used in currently running DWDM systems without any additional modifications. This means that virtually every node in an existing DWDM network is reachable. In addition, the transmit power of the GBC Photonics module can be very precisely adjusted in the range of 7dB. The solutions used in this module made it possible to achieve an average power consumption of less than 22W.
The new GBC Photnics module is fully tunable in the C-band, which allows you to set the transmission channel you need within 10 seconds. The channel grid is also adjustable, so it can be used in Flex-Grid systems with maximum efficient use of available bandwidth.
GBC Photonics universal modules can work in routers and switches of all leading manufacturers of network and transmission equipment. We confirm this in our own network laboratory.
Huge savings with IPoDWDM
The 400G ZR+ 0dBm GBC Photonics modules are ideal for optimizing DWDM systems towards IPoDWDM. The concept of IP-over-DWDM assumes that optical transport modules are mounted directly in IP devices — routers or switches, and transponders are eliminated from the network.
Operators' experience shows that IP-over-DWDM implementations bring investment cost savings of up to 65% in backbone networks compared to traditional wave propagation systems built on transponders and muxponders. Data center space savings are up to 80 percent, and power reductions can range from 70 percent at the edge of the network to 90 percent at the network backbone, depending on the area of the network. It's the perfect way to build sustainable networks!
