Description

Tunable DWDM XFP transceiver

Tunable XFP transceiver 中文名称 为 可调谐 XFP 光模块, 是一种可热插拔的，独立于通信协议的光学收发器，其特点是工作波长可以调谐的，用于10G bps的SONET/SDH，光纤通道，gigabit Ethernet，10 gigabit Ethernet和其他应用中。

F-tone 10G XFP Tunable实现量产。作为10G产品线的重要组成部分，DWDM光收发模块被广泛应用于主干网和城域网传输，相对于TDM光收发模块，DWDM能最大限度的利用光纤资源，以100GHz或50GHz波长间隔，覆盖40km到120km，实现多达100个通道的信号传输。

10G XFP Tunable的量产，是对F-tone已经实现量产的10G SFP+和XFP系列DWDM固定波长产品的重要补充。Tunable可以节省多达100个通道的备货和生产工作量及资金占用，随着Tunable产品的供应和成本改善，预计Tunable产品年化增长率超过20%。
F-tone XFP Tunable产品功耗低，性能优异，性价比高，具有很强的市场竞争力。F-tone XFP Tunable产品支持80个标准波长可调，其波长范围覆盖了整个C波段，频率间隔为50GHz。具有自动波长锁定功能，波长精度高达0.02nm，传输距离达80km，支持速率从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.
