With the growth of optical fiber network customers, we can't satisfy the current network resources with the increasing demands for lower cost and higher capacity. Thus, how to upgrade the power successfully for your system? In this writing, we will give the answers by describing the BiDi technology here.
A Description of BiDi:
BiDi technology allows the transceiver module to receive and transmit data from the interconnect network devices (such as network routers or switches) through a single fiber optic saving fiber expenses. BiDi communication is the primary and essential form of WDM, and we have equipped the BiDi transceivers with WDM diplexers/couplers utilizing two wavelengths. Among these wavelengths, one is for downstream, and one is for upstream communication.
It also suggests that we should deploy the BiDi transceivers in pairs, every part transfers at an opposing wavelength. For instance, In point A, there is a transceiver that transfers TX upon 1310 nanometers toward B point on an SMF. From point B, we have a BiDi optical transceiver that gets RX upon 1310 nanometers and transfers back to spot A upon 1550 nanometers on a similar fiber; later in spot A, the frequency of RX is upon 1550nanometers.
How Many Types of BiDi Technology are Accessible?
BiDi technologies are accessible at different wavelength rates and reach 1 Gigabit/10 Gigabit SFPs, the most familiar types we use in current networks. We have designed them for 1 Gigabit/10 Gigabit deployments and can get to 80 kilometers distance. BiDi transceivers are also attainable for the XFP form factor for 10 Gigabit. Besides the prevailing BiDi optical transceivers, 40 Gigabit BiDi, 400 Gigabit BiDi, and 100 Gigabit BiDi optical transceivers are in the marketplace. They have become an ideal choice for transferring data within the fiber optic part of 10 Gigabit wireless networks.
The Quad Small Form Factor Pluggable 40 Gigabit/100 Gigabit BiDi supports links to 500 meters/150 meters upon OM5 MMF with an LC duplex connector interface. 100 Gigabit BiDi and 40 Gigabit BiDi optical transceivers carry two different channels in distinct directions upon a single fiber strand. It simplifies fiber optic design and controls the expenses by magnifying the capability of the current fiber infrastructure. Moreover, the 400 Gigabit BiDi module is a 100 Gigabit BiDi approach’s quad version using four fiber optic pairs (compatible with frequently installed infrastructure like 4+4 optical fiber MPO).

A Great Need to Develop Network Capacity with the BiDi Technology:
The main reason for using BiDi technology is the growing bandwidth requirement nowadays.
• Countless new devices: With the frequent arrival of new devices into IoT (Internet of Things), companies demand bandwidth to control the data that these new devices are receiving and transmitting.
• Massive traffic within the cloud: Because of the development of modern devices and companies looking to benefit from massive data, we should maximize the capability for enormous traffic within the cloud.
• Complicated traffic within the data center: Data centers tend to shift a growing amount of traffic inwardly, which data moved from data centers to the customer and back. Thus, we require more bandwidths for data centers to maintain traffic flowing fluently.
• Consideration of increasing application as services: Now, many companies consider software service instead of a product, and it causes the online solutions of software to turn to extra bandwidth to work correctly.
• For virtualization, we need additional bandwidth: Regarding IDC Virtual Machine Software Forecast, companies are utilizing different new machines for each server, which produces a demand for significant I/O functionality from every rack to deliver the flexible scale and capacity needed.
40Gigabit/100 Gigabit BiDi Solution:
With less power consumption (less than 3.5 watts) and fixed chips ii-vi characteristics, we have newly launched 40 Gigabit and 100 Gigabit BiDi optical transceivers. They can provide a fiber optic resources saving, high-performance, and low-cost 40 Gigabit/100 Gigabit connectivity for data centers and clouds. Moreover, QSFP 40 Gigabits and 100 Gigabits BiDi optical transceivers can ideally upgrade short-range connections from 10 Gigabit while utilizing your current 10 Gigabit duplex MMF wiring infrastructure.
You can achieve 40/100 Gigabytes per second performance without displacing the 10 Gigabit fiber optic cable sub-structure, which protects fiber optic resources. We can also shorten the waiting period to enhance your required network capability.
