Speed Carrier DWDM System

SPEED-CARRIER 5U - 16 slot universal system

The SPEED-CARRIER with its 5U size is one of the most versatile and flexible 19“ chassis available in today‘s telecommunication market. An outstanding port density can be achieved by integrating up to 16 system and management module in one chassis. The SPEED-CARRIER 5U supports all types of SPEED transponder modules up to 2.5 Gbps or 10 Gbps, WDM units, TDM modules and EDFA as well as RAMAN amplifiers. The clever and future-proof concept is already designed for upcoming high-speed applications without any additional costs. Redundant power supplies for 230 V AC, 24 V DC and 48 V DC are  available in various power classes and can also be used in mixed operations. An intelligent and redundant on-demand cooling system is provided which locates heat sources for selective cooling. This feature extends the life-time of a cooling module and thus provides stability for the entire platform. The SPEED-CARRIER 5U features a redundant on-demand cooling system which selectivity cools only modules with high temperatures. This extends other chassis inside the same rack. Therefore the required space is identical to those of a 3U system. A management connection can be realized by a standard copper interface (RJ45) or a switched optical SFP port. Furthermore management information – even of 3rd party systems – can be transmitted to a central location by using a separate wavelength.

SPEED-CARRIER 1U - 4 slot universal system

This SPEED-CARRIER 1U size is an extremely flexible and compact chassis. Just four slots provide an outstanding port density for powerful access and aggregation modules as well as optical amplifiers. This chassis can be used for multiple purposes e.g. for integration of passive SPEED-CWDM multiplexer or for up to four active SPEED rack mounted modules. A redundant AC or/and DC power supply – mixed operation possible as well – creates a platform redundancy for highly available networks. No minimum distance to other units is required because of the perfected lateral concept for air circulation.

Compatible transceivers

Compatible transceivers are standardised modules that are used among others products. The most common transceiver types are the following:

• GBIC (Gigabit Interface Converter)
• SFP (Small Form Factor Pluggable)
• XENPAK (10 Gigabit Ethernet)
• X2 (10 Gigabit Ethernet)
• XFP (10 Gigabit Small Form Factor Pluggable)

The advantage of “pluggable” transceivers is that they are easy to install as network components. This enables a fast adaptation to new interfaces (e.g. CWDM, DWDM, longer distances, etc.), reduction of spare parts and cost control. Top-quality transceivers contain integrated diagnostic functions for monitoring of temperature and optical input and output levels. “Pluggable” transceivers are equipped with an EEPROM that is used by system vendors for integrating extra vendor-specified information. Therefore those transceivers are “correctly” identified by the system components for providing full functionality. Compatible SFPs are available for nearly all major system vendors as shown below:

Cisco Systems; Nortel Networks; Juniper Networks; 3COM; Enterasys Secure Networks; Brocade certified; HP; Extreme Networks; Foundry Networks; Avaya; Huawei; QLogic certified; Marconi; Alcatel-Lucent; D-Link; Riverstone Networks; Linksys.

2/5 channel DWDM band-filter

The SPEED-DWDM 21/51 is designed as Mux/Demux band-filter module providing five bands, each containing 8 x 100 GHz DWDM channels. At interim locations by interconnection of several DWDM channels SPEED-DWDM 21/51 offers an easy way to patch DWDM channels in different directions simultaneously. While offering a low insertion loss ≤ 1.5 dB and 2.0 dB for 8 DWDM channels. This state- of-the-art concept reduces the overall attenuation and number of patches, as it prevents a coupling and decoupling of individual DWDM channels.
