With the rapid progress of the internet, big data, cloud computing, and additional bandwidth-intensive implementations, 100 Gigabit devices are most common to observe in fast-growing data centers and cloud services. The requirement for 100 Gigabits fiber optics develops accordingly. This article will discuss dual-rate fiber optic transceivers: OTU4 QSFP28 and 100GBASE-LR4 fiber optic transceivers and OTU4 QSFP and 100GBASE-ER4 fiber optic transceivers.

A Description of 100/112G QSFP28 Dual-Rate Optical Transceiver:

A dual-rate optical transceiver means that a fiber optic transceiver can favor two different data rates. The modern dual-rate 100 Gigabit optical transceiver selects 112 Gigabit OTU4 (28Gigabit per channel) and 100 Gigabit (25 Gigabit per channel). Adaptable to the IEEE 802.3ba 100GBASE LR4/ER4, OUT 411-9D1F, and QSFP28 MSA demands, this type of module is a pluggable fiber optic transceiver with LC duplex fiber connector interface for extensive-range data transmission and interconnect implementations.

We have two types of 100 Gigabit QSFP dual-rate optical transceivers regarding the transmission range. One is 112GBASE-OTU4 and 100GBASE-LR4 QSFP28 dual-rate optical transceiver covering 10 kilometers, 20 kilometers, and 25 kilometers communication. We have designed the other 112GBASE-OTU4 QSFP28 and 100GBASE-ER4 dual-rate optical transceiver for 30 kilometers and 40 kilometers for long-distance communication. We have fixed the highest rate as either the 112Gbps or 103.1Gbps when shipping and cannot modify later. We have specifically designed the optical transceivers in the table below to support high-performance data transmissions and telecoms equipment for demanding implementations like data center aggregation, switch, and router interlinks.

Operating Technique of 100/112 Gigabit QSFP Dual-Rate Optical Transceiver Module:

Dual-rate 100 Gigabit fiber optic transceiver module gets the shape of a four-lane QSFP28 with four input channels of 25 Gigabits per second fiber optic data to four Local Area Network WDM fiber optic signals. The optical module de-multiplexes 100 Gigabits per second fiber optic input within four Local Area Network WDM fiber optic signals channels. After that, it multiplexes them into one channel for 100 Gb/s fiber optic transmission. It later changes them to four output channels of electric data.

How to Utilize 100 Gigabit Dual-Rate Optical Transceiver:

Dual-rate 100 Gigabit transceiver module provides four independent receive and transmit channels, each competent of up to 28 Gigabits per second operation for a total bandwidth of 112 Gigabits per second. We have designed this module for OTN applications and 100 Gigabit Ethernet, and it possesses one LC port associated with an industry-level LC duplex SMF optic cable.

We recommend 100 Gigabit LR4 dual-rate fiber optic transceivers for 100GBASE-LR4 Ethernet connections and Transport Network) OTU4 411-9D1F. Quad Small Form Factor Pluggable-ER4-100 Gigabit dual-rate optical transceivers are for 100GBASE-ER4 Ethernet connections, Client-side 100 Gigabit Telecom links, and Infiniband DDR and QDR interconnects. Contrary to 1 Gigabit/10 Gigabit dual-rate SFP+, we can use both 1GbE and 10GbE connections to facilitate the conversion from 1 Gigabit per second to 10 Gigabits per second systems, and we cannot use this dual-rate 100 Gigabit transceiver interchangeability. We cannot apply the transceiver which SDH devices use to Fiber Channel or Ethernet.

NOTE: We deliver this transceiver in ESD secure packaging. We should remove it from packaging and handle it only in an ESD secured environment.

Conclusion:

The launch of 100 Gigabit dual-rate optical transceivers: 112GBASE-OTU4 QSFP28 and 100GBASE-LR4 together with 112GBASE-OTU4 QSFP28 and 100GBASE-ER4 is empowering the fiber optic technology industry with a low-cost path for advancing to 100 Gigabit connections. We can design dual-rate 100 Gigabit optical transceivers compatible with various leading brands like HP, Cisco, Juniper, etc. Furthermore, we examine every fiber optic transceiver to ensure the users get the fiber optics with excellent quality.
