说明书 光收发模块及光纤连接器
[1] 本申请要求于 2008年 3月 24日提交中国专利局、 申请号为 200810085789.X、 发 明名称为"光收发模块及光纤连接器"的中国专利申请的优先权， 其全部内容通过 引用结合在本申请中。
[2] 技术领域
[3] 本发明涉及一种通信设备技术， 尤其涉及一种光收发模块及光纤连接器。
[4] 发明背景
[5] 目前使用的通信设备如路由器、 以太交换机等需要提供大量的 GE和 10G光接口 eSFP (enhanced Small Form-factor
Pluggable, 增强型小型光收发一体化模块， 可热拔插） 、 XFP (lOG Small Form-factor Pluggable, 10G光收发一体化模块， 可热拔插） 和 SFP+ (Small Form-factor Pluggable
Plus, 下一代 SFP， 用于 10G速率传送） 凭借简洁的电接口特性、 较小的体积和 灵活的可热插拔特性， 成为通信设备提供 GE (SFP) 和 10G (XFP、 SFP+) 光接 口的首选光收发模块。 eSFP、 XFP和 SFP+的电接口特性、 光接口特性和尺寸等 已经形成了标准和规范， 并得到了广泛应用。 与 eSFP、 XFP和 SFP+配合使用的 是 LC光纤连接器 （光纤的接头） ， 用于引出光纤与外部设备互连。 通信设备的 线卡面板可以提供较高密度的 GE和 10G光接口。
[6] 目前通信设备如交换机和路由器等， 其线卡均使用 eSFP提供 GE光接口。 下面 以 eSFP为例对线卡面板的结构进行说明。 如图 1所示， 光口连接状态指示灯 2— 般都是从单板内部直接引出到线卡面板 3上， 指示灯 2由单板内独立的点灯电路 驱动。 指示灯 2在线卡面板 3上放置于 eSFPl的两侧； 或如图 2所示集中放置在线 卡面板 3的某一位置。
[7] 从上述现有使用 eSFP的线卡面板设置光口连接状态指示灯的结构中， 发明人发 现上述现有技术至少存在以下问题：
[8] 目前光口连接状态指示灯直接引出到线卡面板， 占用面板面积。 若放置在光接 口两侧， 则占用面板宽度； 若集中放置在某一位置， 则占用面板长度。 导致线 卡在一定高度、 一定槽间距的规格下， 线卡面板出线密度降低， 不能充分利用 面板的面积出线。 这导致路由器和以太交换机等通信设备的单槽位出线能力、 单框出线能力降低， 降低了产品的性价比和市场竞争力。
另外， 虽然指示灯引出到面板， 可以指示端口状态， 但在线卡大量出线的吋候 ， 特别是相邻线卡槽位也大量出线的吋候， 光纤就会遮档指示灯， 难以观看其 状态， 给维护带来较大困难。
对于出 10G接口 （XFP和 SFP+) 的线卡， 也有相同的情况。 现有技术也是将指 示灯直接引出到线卡面板， 占用线卡面板面积， 降低出线密度。 同吋也会给维 护带来不便。
发明内容

[36] 实施本发明的方式
[37] 本发明实施例提供一种光收发模块及光纤连接器， 针对路由器、 以太交换机等 通信设备的线卡面板上设置的指示灯占用面板面积， 降低出线密度， 而且在线 卡大量出线的吋候指示灯被遮档， 难以观察， 不便于维护管理的情况， 提出一 种集成端口状态指示功能的光收发模块 （包括但不限于 eSFP、 XFP、 SFP+、 SFF
(Small Form
Factor, 小型光收发一体化模块， 不可热拔插） ） ， 使指示单元不再占用线卡面 板面积， 且可以通过 LC光纤连接器的透明或局部透明护套透光以指示端口状态 的光收发模块， 达到提高线卡出线密度， 方便操作维护的目的。
[38] 为便于理解， 下面结合附图和具体的实施例进行说明。 由于 eSFP作为光收发模 块使用的较多， 因此下述的实施例中， 以 eSFP为例进行说明， 而其它光收发模 块 （包括但不限于 XFP、 SFP+、 SFF) 的情况与此类似， 不一一列举， 但不因光 收发模块的具体类型对本发明构成任何限制。
[39] 实施例一
[40] 本实施例提供一种光收发模块， 可以用于路由器、 以太交换机等通信设备上， 该光收发模块除具有现有的光收发模块的基本功能外， 还可以指示该端口的工 作状态， 具体包括：
[41] 光收发模块主体， 所述光收发模块主体包括光纤接入腔及电路部分；
[42] 所述光纤接入腔内设置有光纤接口、 指示单元， 所述光纤接口用于与光纤连接
[43] 所述电路部分设置在所述光收发模块主体内， 用于对光收发模块的收发信号进 行处理， 根据光收发模块收发信号的状态驱动所述指示单元；
[44] 所述指示单元与所述电路部分连接， 用于指示所述光收发模块收发信号的状态
[45] 其中， 所述的指示单元为指示灯 Al， 指示灯 A1的发光端指向光纤接口位置。
[46] 如图 3所示， 所述的指示灯 A1可以设置在光纤接口 A2的接入腔内部， 指示灯 A1 的发光端指向光纤接口 A2位置。
[47] 下面以 eSFP作为光收发模块为例进行说明：
[48] 如图 4、 图 5、 图 6所示， 在 eSFP内集成端口状态指示灯 Al， 指示灯 A1设置在光 纤接口 A2处， 即 eSFP的光纤接口 A2的接入腔内部与 LC光纤连接器护套 A21的接 触面 A4处。 当 LC光纤连接器插入 eSFP的光纤接口后， 使指示灯 A1的发光端能照 射到 LC光纤连接器的护套 A21。 图 4示意了 eSFP的光纤接口的剖面结构示意图。
[49] 如图 7所示， 在 eSFP的电接口中定义了 I2C引脚， 可以利用该引脚传送指示灯 A 1的点灯信号， 在 eSFP内增加 I2C解码电路， 用来驱动 eSFP内集成的端口状态指 示灯 Al。
[50] 由于目前的 eSFP电接口中的 I2C接口只用于诊断、 传送告警， 不具备点灯功能 。 因此需要在 eSFP的控制模块中集成 I2C的解码电路模块， 点灯信号通过 I2C传 送， 由解码电路解码后驱动所述的指示灯。 其中的解码电路模块可以根据 eSFP 实际使用的电接口芯片选择相应的常规解码电路模块， 只要能达到驱动指示灯 即可， 不对本发明构成限制。
[51] 上述与 eSFP的光纤接口 A2连接的 LC光纤连接器的护套 A21可以釆用透明材料 ， 制成全透明或局部透明， 将光纤 A5的光纤接头 A22设置在护套 A21中， 当 LC光 纤连接器插入 eSFP的光纤接口 A2后， 使 eSFP内集成的状态指示灯 A1的光能可以 透过 LC光纤连接器的护套 A21透传出来， 在线卡面板位置 A3的外面均可以看到 通过护套 A21透传出的光。
[52] 这样， 当 LC (小型卡接式方形光纤连接器） 光纤连接器插入 eSFP的光纤接口 A 2后， 若该光收发端口状态激活 （如： 链路连通） ， eSFP的状态指示灯就会点亮 ， 并通过 LC光纤连接器的透明 （或局部透明） 护套透光， 从而指示该光收发端 口状态激活。 若该光收发端口有数据传送， eSFP的状态指示灯就会呈闪亮状态 ， 同吋从线卡面板位置 A3外面看则 LC光纤连接器的透明 （或局部透明） 护套也 会闪亮， 指示数据传送状态。
[53] 在 eSFP中釆用这种方式设置指示灯， 不但结构简单， 且可以不占用线卡面板的 面积， 保证了出线的密度， 又可以方便的指示各端口的工作状态， 使用方便， 便于所在通信设备的管理维护。 实际中， 指示单元可以设置两个， 一个可以作 为指示光收发模块接收数据吋状态的接收指示单元， 另一个可以作为指示光收 发模块发送数据吋的发送指示单元。
[54] 实施例二
[55] 本实施例中仍以 eSFP为例进行说明， 其中所述的指示单元为指示灯和导光柱， 设置在 eSFP光收发模块内部， 指示灯的发光端通过导光柱引出到光纤接口位置 ， 即可以通过导光柱将指示灯的发光端发出的光引出到光纤连接器的接入腔内 部， 其它同实施例一。
[56] 具体如图 8〜 11所示， 本实施例中将 eSFP内集成端口状态指示灯 B 1的位置改变 ， 指示灯 B1不直接设置到光纤接口 B2位置 （即 eSFP的光纤接入腔内部与 LC光纤 连接器护套 B21的接触面 B4处） ， 而设置在 eSFP内部， 通过导光柱 B11引出到光 纤接口 B2位置 （即 eSFP的光纤接入腔内部与 LC光纤连接器护套 B22的接触面 B4 处） 。 [57] 当 LC光纤连接器插入 eSFP的光纤接口 B2后， 若该光收发端口状态激活 （如： 链路连通） ， eSFP的状态指示灯 B1就会点亮， 并通过导光柱 B11将光引出到 LC 光纤连接器的透明 （或局部透明） 护套 B21 , 通过所述的透明 （或局部透明） 护 套透光， 从而指示该光收发端口状态激活。 若该光收发端口有数据传送， eSFP 的状态指示灯就会呈闪亮状态， 经导光柱 B11将光传导到护套 B21上， 从线卡面 板位置 B3外面看则 LC光纤连接器的透明 （或局部透明） 护套 B21也会闪亮， 指 示数据传送状态。
[58] 本实施例中， 将指示灯设置在 eSFP内部， 更便于 eSFP的设计， 充分利用了 eSF P内部空间， 减少了 eSFP光纤接口处的元件拥挤。 减少了将指示灯集成到 eSFP内 部的复杂度。
[59] 实施例三
[60] 本实施例提供一种光纤连接器， 该光纤连接器可以用于上述实施例中所述的光 收发模块上， 可以作为 LC光纤连接器或 SC (Square
Connector, 卡接式方形光纤连接器） 光纤连接器使用， 该连接器包括：
[61] 用透明材料制成的全透明或局部透明的护套， 护套透明部分与光收发模块的指 示单元对应， 用于将光导出， 护套形状与光收发模块的光纤接口相匹配。
[62] 上述光纤连接器用在本发明实施例所述的光收发模块上吋， 通过透明护套可以 将光收发模块的指示灯发出的光直接透传出来， 使用者可以在设置该光收发模 块的线卡面板的外面方便的观察端口的使用状态， 不会出现被出线的光纤遮档 指示灯的情况。
[63] 上述各实施例中仅以 eSFP为例进行描述说明， XFP、 SFP+、 SFF等其它光收发 模块可以釆用相同的处理和实施方式。
[64] 综上所述， 本发明实施例中由于光收发模块内部集成指示灯， 当所述光收发模 块用在通信设备 （如： 路由器、 以太交换机等） 中吋， 节省了通信设备线卡面 板上指示灯的面积， 提高线卡面板的出线密度。 并且利用 LC光纤连接器的透明 或局部透明护套透光发亮来指示端口状态， 比面板指示灯更直观， 使维护更方 便。
[65] 以上所述的各实施例是为说明本发明的技术方案， 各实施例之间不具有前后的 次序关系， 并且不因各实施例的序号造成限制。 且各实施例仅为本发明较佳的 具体实施方式， 但本发明的保护范围并不局限于此， 任何熟悉本技术领域的技 术人员在本发明揭露的技术范围内， 可轻易想到的变化或替换， 都应涵盖在本 发明的保护范围之内。 因此， 本发明的保护范围应该以权利要求的保护范围为 准。
