Transponder, Tunable, C/L-band, 10 Gb/s, MSA (7100 Series)

The JDSU Agile Transmission Modules family includes tunable transponders and tunable lasers. The flexibility enabled by JDSU's transponders is critical to the successful and rapid deployment of next generation, IP-based voice, data and video services which are driving new network management challenges for communications service providers. They also support applications, from ultra long haul to metro networks, in a single platform.

The 7100 series 10 Gbps Universal Transponders are MSA compliant, widely tunable, long-reach modules incorporating a transmitter and receiver in the same physical package. The user can choose either a full C-band or full L-band module. The module has a 300-pin connector for the electrical interface and two fiber pigtails (with user-specified optical connectors) for optical input and output ports. The module is compliant with ITU 691 STM-64 L-64.2a and Telcordia GR-253 Issue 3 LR2-c for optical interface, and with OIF-SFI4-01.0 (previously OIF99.102) for the electrical interface.

In the transmit direction, the transponder module multiplexes sixteen 622 to 693 Mb/s electrical signals into a single 9.953 Gbps to 11.1 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 G691 and G.692. The wavelength of the optical transmitter is user programmable over the full C-band or L-band using commands sent via the I2C™ interface. The transponder module synthesizes a high frequency clock (9.953 to 11.1 GHz) from either a 155 to 173 MHz or a 622 to 693 MHz input clock, selected by the user.

In the receive direction, the transponder module accepts a 9.953 to 11.1 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 to 693 Mb/s output signals and its associated clock.
