There’s a fresh addition to Cisco’s Single-Lambda 100G group of QSFP28 optics that delivers 10km achieve. It’s called 100G LR and may be the blue one shown right here:

In this blog series we’ve touted Single-Lambda 100G optics and how it allows system operators to migrate easier to 400G optics also to upcoming 100G optics within a low-price 100G form aspect. It began with the 2km achieve 100G FR. After that we introduced the 500m reach 100G DR for data middle applications. Now, because of Cisco Optics improvements, we are presenting the 100G LR (Product ID: QSFP-100G-LR-S).

100G LR shares the huge benefits common to all or any of our Single-Lambda 100G optics, like manufacturability and interoperability with 400G optics. Take care not to confuse it with another 10km optic that is around for a long time, the 100G LR4. The brands are deceptively comparable (LR and LR4), but they’re different and don’ quite;t interoperate with one another at all.

The brand new 10km reach capability expands the Single-Lambda 100G portfolio’s utility beyond networks which are contained within structures. At 10km, the PAM4 silicon photonics technologies can connect different structures that could not even maintain the same town. For instance, operators of campus networks will see the 100G LR to become a great choice, particularly if it’s for a greenfield deployment and there is absolutely no legacy 100G LR4 to possess to interoperate with. Hyperlinks between core switches, or even between aggregation and primary switches may necessitate this distance.

As exciting as that is, the Single-Lambda 100G optics story is from over far. Stay tuned!
