10Gb/s Tunable DWDM (Full C-band Wavelength, 50 GHz ITU grid) SFP+ 80km Optical Transceiver Module
The 10Gb/s tunable SFP+ transceiver is a high performance integrated fiber optic transceiver that provides a high-speed serial link at signaling rates from 9.95 Gb/s to 11.35 Gb/s. It complies with the 10 Gigabit small form factor pluggable (SFP+) multi-source agreement-MSA Specification(SFF-8431) and Tunable SFP+ for ITU Frequency Grid Applications(SFF-8690). The tunable SFP+ module complies with the ITU-T G.698.1 standard with 50 GHz channel spacing for SONET OC-192, SDH STM-64, DWDM 10GBASE-ZR Ethernet, and DWDM 10G Fiber Channel applications.
The tunable SFP+ transceiver integrates the receiver and transmits path on one module. On the transmit side, the 10 Gbps serial data stream is recovered, retimed, and passed to a modulator driver. The modulator driver biases and modulates a C-band-tunable integrated laser Mach-Zehnder (ILMZ), enabling data transmission over single-mode fiber through an industry-standard LC connector. On the receiver side, the 10 Gbps data stream is recovered from an APD/ trans-impedance amplifier, retimed, and passed to an output driver. This tunable SFP+ module features a duplex industry-standard LC connector.
The tunable SFP+ transceiver provides a full C-band window covering 1528nm to 1568nm for DWDM optical networks, which meets the need of the rapid increase in the volume of communications traffic from telecom carrier and operator. The tunable DWDM SFP+ module can replace the fixed DWDM channel SFP+ transceivers that are currently used while reducing the large stock since all wavelengths can now be covered with one transceiver module.
Additionally, the 10G/bs tunable DWDM SFP+ ZR optical transceiver provides digital diagnostic functions via a 2-wire serial interface, which allows real-time access to the following operating parameters: transmitted optical power, received optical power, transceiver temperature, laser bias current and transceiver supply voltage. It also provides a sophisticated system of alarm and warning flags, which may be used to alert end-users when particular operating parameters are outside of a factory-set normal range.
