FES-6942 Overview
The FES-6942 series provide a two fiber, and four copper (RJ45) ethernet ports. This gives you
five links (one fiber and four RJ-45) plus the Internal Link interface. Each card uses a standard
SFP with an FP 1310nm laser and PIN receiver. High power and CWDM transmitters are
optional, as is a high sensitivity receiver.
The FES-6942 series requires the 8320AR-056 Full Rear Module which includes one LC duplex
connector and four RJ-45 connectors.
CWDM and High Sensitivity Models
Options are also available with Coarse Wavelength Division Multiplexing (CWDM) transmitters,
with a standard or high sensitivity receiver. The high sensitivity models are indicated with an H in
the model number (e.g. FES-6942-27H). The CWDM models are identified with a two digit
suffix as indicated in
Table 4.2 The wavelength for each model are also indicated.
