The Olson Technology, Inc. LaserLite Model OT-1000-HH 1GHz SuperMod
(Direct Mod) 1550nm Optical Transmitter is a cost effective, high quality,
full-featured 1RU 19" optical transmitter. Designed for optical transport of
forward path analog, return path and digital QAM broadcast signals, the OT­1000-HH transmitter is ideal for CATV Hybrid Fiber Coax (HFC) applications
and Fiber-to-the-Premise (FTTP) deployments using Active/Passive Optical
Network (AON/PON) architectures.

The Model OT-1000-HH transmitter utilizes a high-quality, DFB, low-chirp,
optically isolated DWDM laser that uses advanced predistortion, SBS and
pre-chirping technology to provide excellent signal quality. Often referred to
as a Direct Mod 1550 nm transmitter, the OT-1000-HH SuperMod transmit­ter approaches External Modulator performance levels at distances from 0
to 20km at a substantially lower cost. The transmitter operates in the ITU­grid wavelength with adjustable wavelength to ±100GHz when used with the
Network Controller. The Network Controller can control a wide range of
transmitter parameters.

The OT-1000-HH provides exterior RF and optical connections and test
points. These are the perfect companion to Olson Technology’s LaserLite
OTEA-CO, OTEB-CO and OTEA-CM series EDFA’s and the MetroNode
Model OTMN-x and PremiseNode Model OTPN-x product families, but is
also designed to operate seamlessly with optical receivers and/or nodes
from most leading manufacturers.
