Transponder, Tunable, C/L-band, 10 Gb/s, MSA (7500 Series)

/imagesproducts/7500_Tunable_web.jpg



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 I2C™ 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.
