PRODUCT INTRODUCTION
1. Product Introduction
The TranScend is a modular chassis (1RU platform) that uses plug-in modules which can elegantly simplify the return path
transport when used in conjunction with the I-HUB platform. This platform supports a variety of advanced products from ATX
to revolutionize the CATV optical access industry. This product is available in either AC or redundant DC (-48V) powering. It
can accommodate up to four plug-in modules. Currently available modules include:
1. High Sensitivity Quad Receiver for RFoG return path with the capability for built-in express ports.
2. Standard Sensitivity Quad Receiver for RFoG applications.
3. Frequency Stacker for upstream aggregation of four streams of 5-42 MHz.
4. Frequency Destacker to convert the four streams back to 5-42 MHz.
5. RFoG EDFA providing up to four ports at 18 dBm with or without express port capability.
6. Optical Switch for path redundancy.
The chassis provides extremely high density and with the express ports built-in, the amount of  ber interconnectivity is
greatly reduced. The chassis supports hot-swapping of the modules. A high level of integration in the modules makes the
modules very compact, thereby reducing the power requirements and minimizing heat dissipation. The chassis has a local
RS232 port, a RJ45 for remote Ethernet communication with the unit and an alarm contact port. The LCD display in the front
panel helps the operator to monitor all the modules plugged into the chassis.
The front and rear views of the chassis show the various ports available on TranScend chassis.

NOTES:

(2) When the express port is built-in, the output power requirement in the RFoG network is reduced
& the EDFA O/P is reduced to reect this reduced power requirement.
(3) The amplier will show slight CNR & output power variations over this range of optical input
power. For minimal CNR impact, an input power of +4 dBm is recommended. Ampliers may
shut down at input optical powers below -3 dBm to prevent excessive noise at the output.
