The Hotcom 100G QSFP28 CWDM4 2km optical transceiver HT-100G-QSFP28-CWDM4-02 is designed for Data Center 100G CWDM4 Ethernet links reach up to 2km with FEC over Single-Mode Fiber (SMF).

The HT-100G-CWDM4QSFP28--02 module converts 4 input channels of 25Gb/s electrical data to 4 channels of CWDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 100Gb/s optical input into 4 channels of CWDM optical signals and then converts them to 4 output channels of electrical data. The central wavelengths of the 4 CWDM channels are 1271nm, 1291nm, 1311nm and 1331nm as members of the CWDM wavelength grid defined in CWDM4 MSA. The high-performance uncooled CWDM DFB transmitters and high-sensitivity PIN receivers provide superior performance for 100-Gigabit Ethernet applications up to 2km links.

QSFP-100G-CLR4100G QSFP28 CWDM4光模块同样为2KM,究竟有什么区别?

随着数据中心流量的不断激增,100G光模块的市场需求也在进一步增加,常见的100G光模块有SR4、LR4、ER4等,不过在实际的应用中,由于光纤链路长度有长有短, 单靠几种类型的光模块不能满足最具性价比的数据中心光网络传输解决方案。
因此,在中长距离中,CWDM4 MSA组织和100G CLR4联盟也分别制定了传输距离为2 km的100G QSFP28 CWDM4标准和100G QSFP28 CLR4标准。那么同样传输距离都为2KM的100G QSFP28 CLR4和CWDM4光模块究竟有什么相同和不同的地方呢?下面将为大家揭晓答案。

相同之处:
1、两者的接口类型都为双工LC;
2、两者都采用CWDM波分复用技术,工作波长都为1270、1290、1310、1330nm;
3、两者都为单模光模块,传输距离都为2KM。


不同之处:
100G QSFP28 CWDM4光模块必须用于具有前向纠错(FEC)功能的光纤链路。
100G QSFP28 CLR4光模块既能用于具有前向纠错(FEC)功能的光纤链路,也能用于不具有前向纠错(FEC)功能的光纤链路。
而在不具有前向纠错(FEC)功能的光纤链路中,100G QSFP28 CLR4光模块也能保持低延迟和低功耗的性能。100G QSFP28 CLR4光模块的这个特点使得其在高性能计算、高频交易等领域更受青睐。
鸿腾光电100G QSFP28 CWDM4光模块和100G QSFP28 CLR4光模块是数据中心2公里传输应用中比较节省成本的解决方案,其中,100G QSFP28 CWDM4光模块的在数据中心的应用更为常见。
