兼容思科CWDM-SFP-xxxx CWDM千兆系列光模塊，基本描述：SFP封裝，1.25G 1000BASE CWDM光模塊，1470/1490/1510/1530/1550/1570/1590/1610納米，單模80公里/100公里,帶數(shù)字診斷功能。

CWDM-SFP-xxxx中的xxxx表示對應(yīng)波長，即CWDM-SFP-1470、CWDM-SFP-1490、CWDM-SFP-1510、 CWDM-SFP-1530、CWDM-SFP-1550、CWDM-SFP-1570、CWDM-SFP-1590、CWDM-SFP-1610等。

該產(chǎn)品支持1.25G傳輸速率，1470/1490/1510/1530/1550 /1570/1590/1610nm中心波長（DFB激光發(fā)射組件），可支持最大傳輸距離100km(單模光纖傳輸介質(zhì)：9/125um SMF)。支持熱插拔，雙纖雙向傳輸，支持溫度范圍（-40℃~+85℃），雙LC接口，帶DDM數(shù)字診斷功能，工作電壓3.3伏。主要應(yīng)用1.25G 1000BASE CWDM Ethernet 80km100km千兆以太網(wǎng)等領(lǐng)域。

F-tone 對兼容思科光模塊的研發(fā)生產(chǎn)，有著完善成熟的技術(shù)，保證了F-tone光模塊很好的兼容應(yīng)用于思科相應(yīng)的設(shè)備上（交換機(jī)，路由器等）。該款產(chǎn)品同行中有著極高的性價比，同時都具有CE，F(xiàn)CC，ROSH等國際認(rèn)證。

以下是兼容思科CWDM-SFP-xxxx光模塊規(guī)格參數(shù):

CWDM-SFP-xxxx CISCO compatible

CWDM光模塊采用CWDM 技術(shù)，可以通過外接波分復(fù)用器，將不同波長的光信號復(fù)合 在一起，通過一根光纖進(jìn)行傳輸，

從而節(jié)約光纖資源。同時，接收端需要使用波分解復(fù)用器對復(fù)光信號進(jìn)行分解。

思科有關(guān)CWDM光模塊的描述：

Cisco Coarse Wave Division Multiplexing (CWDM) Solution allows scalable and easy-to-deploy Gigabit Ethernet (GbE) and Fibre Channel services. The combination of CWDM GBICs and CWDM SFPs and CWDM Optical Add-Drop Modules (OADMs) and Multiplexers enables the design of a flexible and highly available multiservice network. The Cisco CWDM Solution offers a convenient and cost-effective solution for the adoption of optical Gigabit Ethernet in campus, data center, and metropolitan-area access networks.

Cisco CWDM Solution consists of a set of eight different Cisco CWDM GBICs (one for each of the eight different colors or wavelengths), 8 different SFPs, a set of 8 single wavelength/dual channel OADMs, two 4 channels OADM/MUX and an 8 channel MUX along with a CWDM rack mountable chassis.
