Muxponder Cards

Multiplexer Cards for the Aggregation of different Channels to 100 Gbps, 200 Gbps and 400 Gbps

Multiplexer Cards for Aggregation up to 100 Gbps, 200 Gbps or 400 Gpbs

The SPEED-MUX Muxponder Cards enable a direct aggregation of 1/10/40/100/200/400 Gigabit Ethernet, 4/8/16/32 Gigabit Fiber Channel, 5/10/14/25G InfiniBand and OTU-2,-3,-4 to 100 Gbps, 200 Gbps and 400 Gbps and thus offers the user the maximum flexibility for relevant applications.

The pluggable CFP and CFP2 line transceivers transmit 100 Gbps, 200 Gbps and 400 Gbps services via one DWDM channel. Therefore up to 64/96 DWDM channels can be realized for a transmission of up to 25.6 Tbps over only one optical fiber.

With the integrated AES 256 Bit Layer 1 encryption method, a hardware-based encryption with lowest latency and full data throughput is used. This enables a data transfer according to the highest security standards. Encryption is an option and can be activated via special additional license. The activation of the encryption can also be done retrospectively by a software update without replacing the existing system components.

The flagship SPEED-MUX 800G Muxponder Card can also be used as a dual 400G transponder card. This ensures investment protection for the user as part of future network expansions.

Transponder Cards

Converter cards from 100 Mbps up to 400 Gbps

Transponder Cards 100 Mbps - 400 Gbps

The SPEED transponder cards are compact 2, 4 or 6 channel transponder cards. Depending on the customer application and transponder card type, pluggable client interfaces are available for SFP, QSFP+, QSFP28 and QSFP-DD transceivers.

In CWDM and DWDM networks, they convert up to 2/4/6 channels to relevant CWDM and DWDM wavelengths. The multi rate feature supports almost all protocols:

  • 100BaseTX / FX and 1000BaseTX / FX
  • 10/25/100/200/400 Gigabit Ethernet
  • OTU-2,-3,-4
  • STM-1/4/16/64
  • Audio: MADI protocol
  • 1/2/4/8/10/16/32 Gigabit Fiber Channel
  • 5/10/14/25 Gbps InfiniBand

Additionally the SPEED Transponder Cards with integrated 3R (Reshaping, Re-amplification, Retiming) and FEC (Forward Error Correction) function enable error-free transmission over longer distances. The integrated SNMP agent can send SNMP traps to a management system via Ethernet.

Optical Amplifiers

EDFA Modules for the transmission via longer distances

EDFA Amplifier for long Distances

The use of amplifiers can increase the range of the optical transmission system. Depending on the distance to be overcome and existing intermediate locations, three amplifier variants (booster, inline, and pre-amp amplifiers) are available. All SPEED-OTS-5000 amplifier modules amplify up to 64 or 96 DWDM channels in the optical C-band on a fiber pair.

The protocol transparent amplification is independent of the application to be transmitted. The amplifiers can be monitored and configured locally via the Comand Line Interface (CLI), Telnet and WEB-interface or also remotely via the SPEED-NMS Management Card by using the SNMP standard and supported by the user friendly graphical user interface (GUI). An optional remote management via an in-band OSC channel is also available. All optical amplifiers meet the requirements of Laser Class 1M, so no laser safety officer is necessary.

Management Cards

Central Management with SPEED-NMS card

Central Management with GUI and Elementmanager

The SPEED-NMS management card is the central access point of the SPEED-OTS-5000 series. The monitoring and configuration of the system can be performed via a Graphical User Interface, SNMP or per Command Line Interface.

1U and 5U modular rack system

Active and passive 1 or 5 RU modular rack system

The modular rack system with 1 or 5 units (U) SPEED-CARRIER 5U-H and SPEED-CARRIER 1U-H (High Power) can be flexibly equipped with active and passive system cards according to customer requirements. All modules can be put into operation via the front side, are hot-swappable and exchangeable without affecting the remaining data traffic. The rack systems can be used to operate system cards with high bandwidths of up to 400 Gbit/s and AES 256 Layer 1 encryption. This makes the system ideal for DCI applications. The highlight of the 1U variant is its high packing density of up to 3,200 Gbit/s per U.

In both rack systems, an intelligent fan concept means that no ventilation distance to neighboring systems is required. Thus, up to 19 (or 9) slots can be equipped with high and low bit rate system cards as well as an NMS card. Due to the low installation depth and a flexible redundant power supply of 230 V AC or 48 V DC, the system can be used everywhere.

Passive WDM Multiplexer

WDM & CWDM & DWDM & BWDM & ADM Multiplexer as well as DCM and SPLIT Modules

The SPEED-WDM Series includes a variety of passive CWDM and DWDM modules with different numbers of channels. The SPEED-CWDM Series is available in 5, 8, 9 and 16 CWDM wavelengths per system card. The CWDM five and nine wavelengths multiplexers have a cascading port that allows them to be extended by another eight CWDM wavelengths without interruption of the running operation.

Through the use of DWDM modules, up to 64 or 96 DWDM channels can be transmitted over one fiber optic. For each channel, e.g. 400 Gbps application are switched - thus results in a total data rate of 25.6 Tbps per pair fiber optic.

With the help of our cascading concept it is possible to cascade 8 to 40 DWDM channels without interrupting already running services.

With DWDM band filters, DWDM bands with 8 DWDM channels each can be interconnected with lowest signal loss at intermediate locations.

The SPEED-Add&Drop multiplexers are available for CWDM or DWDM applications. Using Add&Drop multiplexers, it is possible to couple and decouple one or more wavelengths in a fiber in a dedicated manner without having to use a CWDM or DWDM multiplexer to extract all wavelengths.

Depending on customer requirements, we manufacture individual CWDM / DWDM modules with different wavelengths, connectors and port numbers for different housing types.

The dispersion compensation module SPEED-DCM compensates the propagation time differences of the different DWDM wavelengths in optical transmission systems. It is a purely passive device which can be equipped along the link for ranges from 20 km to 200 km, depending on the requirements. The dispersion compensation is totally protocol transparent.

The SPEED-SPLIT series enables live monitoring of all wavelengths via an external OSA (Optical Spectrum Analyzer) meter. For this, e.g. SPEED-SPLIT 97/03 provides 3% of the optical power and provides it for the analysis.
