1491 OADM, SM, LC/PC, Fiber opric cassette modul

SKU: FPM76-OADM-1491-SLC
Stock:
excl. VAT

Fiber optic module panel with a built-in OADM, terminated in LC connectors. The module should be mounted in a 1U or 3U panel.

OADM for CWDM wavelengths

The patch panel comes with 2 pcs. OADM for two-way communication

The module should be mounted in a 1U or 3U panel. There is room for 12 modules in the 3U panel and 3 modules in the 1U panel. Various modules can be placed in random order in the patch panels. This ensures a flexible and modular construction that can easily be extended with more modules.

  • Add and dropp from the wide band
  • Independent of protocol and bit speed
  • Insertion loss ; 1.2 dB (express and add/drop on)
  • Can be mounted in 19" and ETSI cabinet/rack
  • Passive, does not need any power supply

DESCRIPTION

OADM/ODM may be delivered in several types of panels and boxes from Foss.  

The most common are:

  • FPM76-modular panel  
  • FP65-1U panel
  • FPD76- wall box DIN  

May also be delivered in most splice closures.  

They are based on reliable passive technology and are delivered with SC or LC interface with PC or APC polished connectors.   


Add/Drop patch cord
This is a patch cord with an integrated add or drop element. It may be used in both directions, but contains only one branch so it will work either as an add or as a drop. 2 patch cords put together will give add/drop in one direction, 4 patch cords makes up both directions. It is well suited when there is no room for a panel, but it will make it more difficult to track where the signal are running compared to using a panel. It may be delivered with SC or LC connectors.  


SYSTEM DESCRIPTION
Passive multiplexers/de-multiplexers for CWDM or WDM are a reliable and reasonable method for transferring several wavelengths/signals over the same fibre (wavelength multiplexing). In this way you may increase the capacity of existing fibre-cable significantly. Combined with OADM you may add or drop separate wavelengths on the way between the end points. A big advantage of using passive wavelength multiplexing is also that the method is protocol– and bitrate independent.

The OADM/ODM units may be delivered both for WDM (1310) and for CWDM-channels. When adding or dropping CWDM wavelengths (1 or more at the time), use OADM/ODM for CWDM. If a standard 1310 signal (not to be confused with a 1311 CWDM signal) is to be added/dropped you need extra bandwidth and the OADM/ODM for WDM (with wideband 1310) must be used.  

Also OADM/ODM units for DWDM-wavelengths may be delivered on request.
