DISPERSION COMPENSATING MODULE
print pdf version
Application
Compensation of positive dispersion
of G.652 single mode fiber (SMF) in
transmission links
Improvement of CSO performance of
fiber-optic links fed by externally modulated transmitters (ES10 and OTXE090)
Improvement of CSO performance of
fiber-optic links fed by directly modulated transmitters (BOT/ OTXD1550X and DS26/BOTS/OTXDS1550X)
Features
Dispersion compensation of nnn = 20, 30, 40, 50, 60, 80 or 100 km of SMF
Very low insertion loss
Compensation over entire C-band
(1530-1560nm)
Low PMD
Available in:
compact housing with pigtails
DCM-nnn-x
19" - 1 HU housing with adaptors
DCM-nnn-x-H
FC/APC, SC/APC or E2000 connectors
