Tunable DWDM XFP transceiver
Tunable XFP transceiver 中文名稱 為 可調諧 XFP 光模塊, 是一種可熱插拔的,獨立于通信協(xié)議的光學收發(fā)器,其特點是工作波長可以調諧的,用于10G bps的SONET/SDH,光纖通道,gigabit Ethernet,10 gigabit Ethernet和其他應用中。
F-tone 10G XFP Tunable實現量產。作為10G產品線的重要組成部分,DWDM光收發(fā)模塊被廣泛應用于主干網和城域網傳輸,相對于TDM光收發(fā)模塊,DWDM能最大限度的利用光纖資源,以100GHz或50GHz波長間隔,覆蓋40km到120km,實現多達100個通道的信號傳輸。
10G XFP Tunable的量產,是對F-tone已經實現量產的10G SFP+和XFP系列DWDM固定波長產品的重要補充。Tunable可以節(jié)省多達100個通道的備貨和生產工作量及資金占用,隨著Tunable產品的供應和成本改善,預計Tunable產品年化增長率超過20%。
F-tone XFP Tunable產品功耗低,性能優(yōu)異,性價比高,具有很強的市場競爭力。F-tone XFP Tunable產品支持80個標準波長可調,其波長范圍覆蓋了整個C波段,頻率間隔為50GHz。具有自動波長鎖定功能,波長精度高達0.02nm,傳輸距離達80km,支持速率從9.95到11.35Gbps。

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.
