Applications
• Universal DWDM transport for Metro,

• Agile optical networks incorporating
ROADM technology
The flexibility enabled by our 7500 series full band tunable transponders is critical
to the rapid deployment of next-generation, IP-based voice, data and video
services that are driving new network management challenges for
communications service providers. They also support applications ranging from
ultra long-haul to metro networks, in a single platform.
The 7500 series 10 Gbps universal transponders are MSA-compliant, full band
tunable, long-reach modules incorporating a transmitter and receiver in the same
physical package. The module has a 300-pin connector for the electrical interface
and two fiber pigtails for optical input and output ports. The module is compliant
with ITU G.691 STM-64 L-64.2a and Telcordia GR-253 Issue 3 LR2-c for optical
interface; and with OIF-SFI4-01.0 for the electrical interface.
In the transmit direction, the transponder multiplexes sixteen 622 – 710 Mbps
electrical signals into a single 9.953 – 11.352 Gbps signal, which is then modulated
onto the optical transmitter output. The optical output meets or exceeds the
SONET specifications stated in Telcordia GR-253, Issue 3 and draft ITU-T G.691
and G.692. The wavelength of the optical transmitter is user programmable over
the full C+ or L-band using commands sent via the I
2
C™ interface. The
transponder module synthesizes a high-frequency clock (9.953 – 11.352 GHz)
from either a 1/64 or a 1/16 input clock, depending on user selection.
In the receive direction, the transponder module accepts a 9.953 – 11.32 Gbps
optical signal and converts it, using a clock and data recovery circuit, into an
electrical equivalent. This electrical signal is then demultiplexed into sixteen 622
– 710 Mbps output signals and its associated clock.
