?H3C设备的不同产品可支持的光模块类型不同，具体请参见各产品安装手册。
?光模块的种类随着时间变化有更新的可能性，所以，若您需要准确的模块种类信息，请咨询H3C 公司市场人员或技术支援人员。
1.2 光模块概念介绍
1.2.1 简介
光模块用于光信号的传输，传输媒质为光纤。光纤传输方式损耗低，传输距离远，在长距离传输方面具有很强的优势。
H3C设备支持多款不同规格的光模块，用户可以根据自己的需要选择合适的光模块，通过光纤进行数据传输。
目前的光模块主要包括：光发送器，光接收器，Transceiver（光收发一体模块）以及Transponder （光转发器）。
H3C设备支持Transceiver，Transceiver的主要功能是实现光电/电光变换，包括光功率控制、调制发送，信号探测、IV转换以及限幅放大判决再生功能，此外还有些防伪信息查询、TX-disable等功能，常见的有：XFP、SFP、SFP+、QSFP+等。
1.2.2 传输速率
传输速率指每秒传输比特数，单位Mbps或Gbps。H3C设备所支持光模块主要提供以下级别的传输速率：100Mbps、155Mbps、622Mbps、1Gbps、2Gbps、2.5Gbps、4Gbps、8Gbps、10Gbps、40Gbps、100Gbps。
1.2.3 传输距离
光模块的传输距离分为短距和长距两种。一般认为2km及以下的为短距离，10km的为长距离。
光模块的传输距离受到限制，主要是因为光信号在光纤中传输时会有一定的损耗和色散。
?损耗是光在光纤中传输时，由于介质的吸收散射以及泄漏导致的光能量损失，这部分能量随着传输距离的增加以一定的比率耗散。
?色散的产生主要是因为不同波长的电磁波在同一介质中传播时速度不等，从而造成光信号的不同波长成分由于传输距离的累积而在不同的时间到达接收端，导致脉冲展宽，进而无法分
辨信号值。
因此，用户需要根据自己的实际组网情况选择合适的光模块，以满足不同的传输距离要求。
1.2.4 中心波长
中心波长指光信号传输所使用的光波段。目前常用的光模块的中心波长主要有三种：850nm波段、1310nm波段以及1550nm波段。
?850nm波段：多用于短距离传输
?1310nm和1550nm波段：多用于中长距离传输
1.2.5 光纤类型
1. 光纤模式（Fiber Mode）
按光在光纤中的传输模式可将光纤分为单模光纤和多模光纤两种。
ITU（International Telecommunication Union国际电信联盟）制定了一系列的通信标准。ITU的标准通过字母编号从A到Z系列，每个字母的后面用数字做编号。ITU通过制定G系列协议定义了光纤标准种类。
(1) 多模光纤
多模光纤（MMF，Multi Mode Fiber）纤芯较粗，可传多种模式的光。但其模间色散较大，且随传输距离的增加模间色散情况会逐渐加重。
多模光纤根据光纤直径和模式带宽的不同，可以分为多个等级，具体介绍请参见表1-2。其中，模式带宽（Modal bandwidth）指的是一段光纤所能通过的最大调制频率脉冲的调制频率和光纤长度的乘积，是一个可以体现多模光纤光学特性的综合指标。
常用的多模光纤为G.651光纤，根据标准，G.651光纤能传输800～900nm、1200～1350nm波长的激光。
表1-2多模光纤分类
光纤模式光纤等级光纤直径（μm）Modal bandwidth at 850 nm（MHz*km）
多模光纤OM1 62.5/125 200 OM2 50/125 500 OM3 50/125 2000
多模光纤的传输距离与其接口类型、中心波长、使用光纤的等级有关，具体关系请参见表1-3。表1-3多模光纤规格表

82m OM3 <
300m
10GBASE-LRM 1310 OM1 <
220m OM2 <
220m OM3 <
220m
(2) 单模光纤
单模光纤（SMF，Single Mode Fiber）中心玻璃纤芯很细（芯径一般为9或10μm），只能传一种模式的光。因此，其模间色散很小，适用于远程通讯，中心波长一般为1310nm或1550nm。
同时，根据TIA/EIA协议，单模光纤塑料护套为黄色，塑料护套上标有SM字样的标签。TIA表示（Telecommunication Industries Alliance）电信工业联盟，EIA表示（ElectronicIndustries Alliance）电子工业联盟。
常用的单模光纤为G.652光纤和G.655光纤：
?G.652光纤是常规单模光纤，零色散点在1300nm，此点色散最小。G.652光纤能传输1260～1360nm、1530～1565nm波长的激光。
?G.655光纤是非零色散位移光纤NZ-DSF（No-Zero Dispersion Shifted Fiber），主要特点是1550nm的色散接近零，但不是零。G.655光纤是一种改进的色散位移光纤，以抑制四波混频。
G.655光纤适合传输波分复用1550nm的激光。
如下表格为G.652光纤和G.655光纤的简单总结：
表1-4单模光纤规格表
光纤名称工作模式波长区域备注
G.652 单模1260～1360nm，1530～
1565nm
常规单模光纤
G.655 单模 1530～1565nm 非零色散
通过上表可以知道，选择G.652光纤可以适配中心波长1310nm、1550nm的光模块。如果要传输波分复用的1550nm的激光，可以选用G.655光纤。在实际选用光纤的时候，根据光纤厂商的产品手册能够查询该光纤符合什么标准。
2. 光纤直径
光纤直径一般采用纤芯直径/包层直径的表示方法，单位μm。例如：9/125μm表示光纤中心纤芯直径为9μm，光纤包层直径为125μm。
H3C设备推荐使用的光纤直径如下：
?G.652常规单模光纤：9/125μm
?G.655单模光纤：9/125μm
?G.651常规多模光纤：50/125μm或62.5/125μm
1.2.6 接口连接器类型
接口连接器用于连接可插拔模块及相应的传输媒质。光纤连接器是光纤通信系统中不可缺少的无源器件，它的使用使得光通道间的可拆式连接成为可能，既方便了光系统的调测与维护，又使光系统的转接调度更加灵活。H3C设备支持的光模块所采用的光纤连接器包括：SC连接器、LC连接器和MPO连接器。
为了保护光纤连接器的清洁，请务必保证在未连接光纤时盖上防尘帽。
1. SC连接器
SC（Subscriber Connector Standard Connector，标准光纤连接器），外观图如图1-1所示。
图1-1SC连接器外观图
2. LC连接器
LC（Lucent Connector or Local Connector，朗讯连接器），外观图如图1-2所示。
图1-2LC连接器外观图
3. MPO连接器
MPO（Multi-fiber Push On）连接器，外观图如图1-3所示。
图1-3MPO连接器外观图
1.2.7 接口指标
除特殊说明外，本文所提供的输出光功率和接收光功率范围两端的值均为平均值。
1. 输出光功率
输出光功率指光模块发送端光源的输出光功率，单位：dBm。
2. 接收光功率
接收光功率指光模块接收端的接收光功率，单位：dBm。
3. 接收灵敏度
接收灵敏度指的是在一定速率、误码率情况下光模块的最小接收光功率，单位：dBm。一般情况下，速率越高接收灵敏度越差，即最小接收光功率越大，对于光模块接收端器件的要求也越高。
4. 饱和光功率
又称光饱和度，指的是在一定的传输速率下，维持一定的误码率（10-10～10-12）时的最大输入光功率，单位：dBm。
需要注意的是，光探测器在强光照射下会出现光电流饱和现象，当出现此现象后，探测器需要一定的时间恢复，此时接收灵敏度下降，接收到的信号有可能出现误判而造成误码现象，而且还非常容易损坏接收端探测器，在使用操作中应尽量避免超出其饱和光功率。
对于长距光模块，由于其平均输出光功率一般大于其饱和光功率，因此请用户使用时关注光纤使用长度，以保证到达光模块的实际接收光功率小于其饱和光功率，否则有可能造成光模块的损坏。
1.3 电口光模块概念介绍
1.3.1 简介
电口光模块用于电信号的传输，传输媒质为5类非屏蔽双绞线，相比光纤传输方式来说，双绞线传输的传输距离较小，只适用于小范围组网环境。
H3C设备仅支持SFP电口光模块。
1.3.2 传输速率
电口光模块的传输速率为1250Mbps。
1.3.3 传输距离
电信号在双绞线中的传输距离为100m，主要是因为电信号在双绞线中传输时存在衰减现象。
衰减（attenuation）是指经过一段时间或者距离后信号减弱。出现衰减的原因是：线缆本身对传输有一定的阻力，从而导致电线号沿线缆传输时逐渐减弱。若传输距离很长的话，信号强度会降得很低，致使信噪比降至可接受标准以下，无法正确分辨信号与噪声而产生误判。
因此，只有在传输距离较短的情况下才可以选择电口光模块。
1.3.4 接口连接器类型
电口光模块采用RJ-45（Registered Jack，注册Jack）双绞线连接器。外观图如图1-4所示。

?BIDI GEPON OLT光模块是一种专用于EPON OLT端设备的千兆SFP模块。需要注意的是通过SFP-GE-PX10-D-SM1490-A模块传输的光信号只能用于10公里版本的ONU设备。
?在测试EPON OLT、ONU端口的光功率时请使用EPON专用的光功率计（H3C使用的光功率计型号为JDSU OLP-57），以确保测量结果准确。
2.8 千兆CWDM模块
2.8.1 外观图
图2-4千兆CWDM模块外观示意图
2.8.2 具体型号及规格
千兆CWDM模块的传输速率为1250Mbps，均采用LC连接器。
千兆CWDM模块采用CWDM技术，可以通过外接波分复用器，将不同波长的光信号复合在一起，通过一根光纤进行传输，从而节约光纤资源。同时，接收端需要使用波分解复用器对复合光信号进行分解。
