STL offers Stellar Fibre as universal fiber

Stellar Fibre offers ITU-T G.657.A2 bend insensitivity but with a mode field diameter the size of ITU-T G.652.D fiber.

This week's High Speed Ethernet Plugfest at UNH-IOL drew more participants than the previous one.

Ethernet Alliance wrapping up latest High-Speed Networking Interop Plugfest

This week’s HSN Plugfest drew a greater number of companies than the previous iteration, including some who joined the Ethernet Alliance just so that they could participate.

MPO-to-MPO is one of several cable assembly categories covered by L-com's recent portfolio expansion.

L-com offers 50/125 OM3, OM4, and OM5 multimode fiber cables

Options for the new assemblies include OFNR or low-smoke zero-halogen (LSZH) jackets; connector pins or no pins; choice of OM3, OM4, and OM5 multimode fiber; and fiber counts of 8, 12, and 24 channels, says the company.

Sales of Ethernet optical modules are expected to decline in 2019 for the first time since 2009. But growth should return next year, LightCounting predicts.

Ethernet transceiver sales to decline 18% in 2019: LightCounting

However, LightCounting states in its new “High Speed Ethernet Optics Report” that purchases of Ethernet optical transceivers should rebound through 2024.

The IC-TROSA was one of several elements of its work OIF display at ECOC 2019 in a manner to its demos at OFC 2019 recorded in these photos.

OIF approves IC-TROSA Implementation Agreement to pave road to 400ZR modules

The IA describes two types of IC-TROSA, each of which is expected to accelerate the development of 400-Gbps coherent optical modules, including those based on the 400ZR IA, in pluggable form factors such as QSFP-DD and OSFP.

Jabil Photonics demos 100G/200G CFP2-DCO coherent optical transceiver

The device leverages a silicon photonics coherent engine from Elenion Technologies and is nearing sampling, according to Jabil Photonics sources at ECOC 2019.

Infinera sees XR optics as a more efficient means to support hub-and-spoke network architectures.

Infinera unveils XR optics single-source coherent point-to-multipoint transmission technology

Infinera sees XR optics, which it plans to make available to optical transceiver vendors and perhaps other partners, as a more efficient means to support hub-and-spoke network architectures than the present point-to-point approach.

Ethernet Alliance High-Speed Networking plugfest, December 2018.

Achieving Multi-Vendor Interoperability in Ethernet: Behold the Plugfest!

It is the Ethernet Alliance’s interoperability test event—the “plugfest”—where the technology’s global reputation for seamless, multi-vendor interoperability is definitively earned.

Company representatives line up at the 800G Pluggable MSA Launch Event at CIOE.

800G Pluggable MSA targets PAM4-based 8x100G, 4x200G transmission for data center networks

The MSA’s specification will support 8x100G and 4x200G optical transmission, with the latter a focus of development within the group.
