Compatible transceivers

Compatible transceivers

Brocade QLogic

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.

DWDM Power Coupler

DWDM Power Coupler

DWDM Power Coupler

The DWDM Power Coupler allows live monitoring of all 80 DWDM wavelengths on external OSA measuring equipment without link interruption. The SPEED-SPLIT series made of passive components, splits the optical signal on a fibre in a predetermined split ratio. A typical field of application are DWDM point-to-point connections, in which 10% of optical power are decoupled and thus provide a monitor port. By using this monitor port, for example OSA (Optical Spectrum Analyzer) equipment is connected. Thereby the initial calibration of the different DWDM wavelengths is simplified or an analysis of the connection during operation is possible. The SPEED-SPLIT WDM module can be equipped optionally with one or with up to four integrated power couplers. The modules are installed in space-saving housing types (SPEED-CARRIER 4.5U and SPEED-CARRIER 1U/B).

Dispersion Compensation Module

Dispersion Compensation Module

The Dispersion Compensation Module is a purely passive module for compensating differences of velocity of various DWDM wavelengths in optical transmission systems. The SPEED-DCM ís available for customized distances starting from 20 km up to 200 km. The dispersion compensation is designed for protocol transparent data rates between 10 Mbps and 40 Gbps. Thus up to 80 DWDM wavelengths (100 GHz grid) can be compensated on a fibre optic link. The SPEED-DCM covers one slot in a SPEED-CARRIER 4.5U or in a SPEED-CARRIER 1U housing. In addition a single-slot housing is available for integration of a SPEED-DCM module.

2/5 channel DWDM band-filter

2/5 channel DWDM band-filter2/5 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.
