BIDI optical module only has one optical port, just need one fiber can simultaneously transmit and receive optical signals, is a solution to save fiber resources. BIDI optical module uses WDM technology to realize the bidirectional transmission of optical signals on one optical fiber. Optical module usually has two ports, the TX is the transmitting port, and the RX is the receiving port. BIDI modu...

With the network market gradually developed from 10G to 40G and 100G, 40G and 100G optical devices have also been widely used in various fields. In the next few years, 100G products will continue to be popular and gradually be widely accepted by the market. 100G CFP series optical transceiver have three package forms: CFP, CFP2 and CFP4 optical transceiver. The 100G CFP optical module is an outlin...

As we all know, the 40G SR4 QSFP+ optical module is the ideal solution for short-range interconnection in 40G networks and has many advantages, but the 40G QSFP+ AOC also has similar function of optical module and is not inferior to the 40G SR4 QSFP+ module or even can replace it to transmit signals. Since both can be 40G short-distance interconnection, then what are the differences between them? ...

100G has a variety of packaging forms, including CFP/CFP2/CFP4, CXP and QSFP28. Among these different 100G packaging forms, QSFP28 optical module has the advantages of high port density, low power consumption and low cost, so it has become the main packaging form of 100G network. Therefore, we will focus on four types of 100G QSFP28 optical modules today. 1.100GBASE-SR4 QSFP28 optical transce...

Today let's learn about the MPO Patch cord. Last time one of our customer bought 100G SR4 MPO 100M, compatible with Juniper QFX5110 Switch.   1.How to connect the 2 transceivers in 2 switches with a patch cord directly? It's a question for him. So I gave him a solution, like the following picture shows. ①we imagine you use Juniper QFX5110-32Q to test the modules. ②100G SR4 MPO ...

EPON and GPON are the two main members of optical network access. Each of them has own advantages, competes and complements each other.The following will compare with them in various aspects. Data Rate EPON provides a fixed up and downlink with 1.25 Gbps, using 8b/10b line coding, and real rate is 1Gbps. GPON supports a variety of speed grades, can support uplink and downlink asymmetric rates, dow...

QSFP+ have Single-mode and multimode, it means QSFP+ optical module works on different types of fiber optic, the single-mode QSFP + use with single mode fiber, and the multimode QSFP + used with multimode fiber. Then what are the differences between them? Where are they applied? What should we pay attention to when we use them? In this article, we will discuss this topic. Optical module difference...

As we all know, currently the mainstream optical communication transmission rate is 40G and 100G on the market, their competition is also fierce. Today we will list some common questions in 40G networks. What are the common solutions for 40G networks? At the core of the 40G network layer, a pair of optical modules are usually connected at both ends of a multimode optical fiber such as OM3 or OM4(M...

It seems that 25GbE is more preferred and accepted by end users, compare with 10GbE and 40GbE. 1.Why Choose 25GbE? While 10GbE is fine, it cannot efficiently for the next-generation Clould and web-scale environments. And 40GbE, isn't cost-effective or power-efficient. So, that's why we need 25GbE. 2.The Cost of 25GbE Wiring Is Lower 40GbE has to be cooperated with MPO fiber to transmit, it would c...
