光模块常见问题
光模块 SFP 和 SFP+ 有什么区别？能混用吗？
SFP 最高支持 2.5G 速率，SFP+ 支持 10G，两者封装尺寸相同但电气速率不同，一般不能混用，插错可能无法识别或降速。选型先确认设备端口速率再选对应模块。北亿纤通提供全速率 SFP/SFP+ 光模块，兼容主流品牌设备，具体兼容型号可联系销售确认。
单模光模块和多模光模块怎么区分？可以混用吗？
看波长和光纤类型：多模一般是 850nm 配橙色 OM3/OM4 光纤，300 米内传输；单模是 1310/1550nm 配黄色 OS2 光纤，可达 10 公里以上。两者不能混用，混用链路不通。北亿纤通单模/多模光模块型号齐全，选型拿不准可联系销售确认。
光模块标注的 DDM 功能有什么用？
DDM（数字诊断监控）可实时读取光模块的温度、电压、发射和接收光功率，提前发现光衰过大、模块老化等问题，是运维排障的重要手段。采购建议优先选带 DDM 的型号。北亿纤通主流光模块均支持 DDM 功能，详情可联系销售确认。
光模块说兼容 Cisco/Huawei，是真的能用吗？
兼容光模块通过写入对应品牌设备的编码信息实现上机识别，功能与原厂一致，价格通常只有原厂几分之一。关键是编码要写对，购买前务必提供设备品牌型号给供应商核对。北亿纤通光模块兼容 30+ 主流品牌，编码可按设备定制，下单前联系销售确认即可。
工业级光模块和商业级有什么区别？
主要是工作温度范围不同：商业级一般 0~70℃，工业级 -40~85℃，工业级在用料和测试标准上更严格，适合室外、厂房等温差大的环境。机房恒温环境用商业级就够了。北亿纤通光模块商业级/工业级/军品级可选，选型可联系销售确认。
