General Description
The TXFP-ZR-Xseries optical transceiver is a high performance and cost effective XFP transceiver modules designed for 10G SDH/SONET, 10G Ethernet DWDM fiber optic transmission applications, designed to support the full range of C-band ITU-T wavelengths data rates from 9.95Gbps to 11.3Gbs and distances up to 80km.This transceiver contains both transmit and receive sections. An MZM, (C-band tunable laser with a wavelength locker) a laser driver and the supporting circuits constitute the transmit path while an APD ROSA, a post amplifier and the supporting circuits form the receive section. A microcontroller handles the communications between the module and the host board as well as the control and monitoring functions for both transmit and receive sections. A Clock and Data Recovery circuit (CDR) functions for both transmit and receive.The transceiver module is fully compliant with the XFP MSA standard and can be hot-plugged into the 30-pin XFP connector on the host board. By limiting inrush currents, the device will not disturb the operations of the host board. The high-speed electrical interface is fully compliant with the XFI standard, providing transmission paths for the 10G signals.
Functional Description
The TXFP-ZR-X series optical transceiver contains a duplex LC connector for the optical interface and a 30-pin connector for the electrical interface. Figure 2 “ Transceiver Block Diagram ” shows the functional block diagram of TXFP-ZR-X series optical transceiver.
Transmitter Operation The transceiver module receives 10Gb/s electrical data and convert it to an optical signal. The transmitter contains a Clock Data Recovery (CDR) circuit that reduces the jitter of received signal and reshapes the electrical signal before the electrical to optical (E-O) conversion. The optical output power is maintained constant by an automatic power control (APC) circuit. The transmitter output can be turned off by TX disable signal at TX_DIS pin. When TX_DIS is asserted high, the transmitter is turned off.Receiver Operation The received optical signal is converted to serial electrical data signal. The optical receiver contains a CDR circuit that reshapes and retimes an electrical signal before sending out to the XFI channel (i.e. XFP connector and high speed signal traces). The RX_LOS signal indicates insufficient optical power for reliable signal reception at the receiver.Management Interface A 2-wire interface (SCL, SDA) is used for serial ID, digital diagnostics and other control/monitor functions. The address of XFP transceiver is 1010000x.MOD_DESEL
signal can be used to support multiple XFP modules on the same 2-wire interface bus. Management interface is compliant with XFP MSA.
