400G transceivers speed optical networks for cable MSOs, data centers

Aug. 10, 2020
Optical transceivers, especially 400G-capable ones, are the key component in enabling more traffic to flow across today's networks.

Precision OT has unveiled a new line of QSFP-DD 400G optical transceivers. The optical module line covers distances between 100 m and 10 km for cable MSO and data center networks.

"Optical transceivers, especially 400G-capable ones, are the key component in enabling more traffic to flow across today's networks," said Chris Page, CTO of Precision OT. 

The company's new, laboratory-tested line of QSFP-DD transceivers comes in four variants, with FR4, DR4, and DR4+ among them. The fourth module is the PRE-QSFP28-FR transceiver, which pairs with the QSFP-DDs for 400G to 4x100G breakout applications.  

Page added, "Single-lambda 100G will be one of the most cost-effective ways for MSOs and data centers to deal with future bandwidth demands, because a single 100G line can reduce the costs of a typical 4x25G architecture by at least 40%. In this way, the use of four lines of 100G and PAM4 modulation can enable the 400G data rates our customers need to ensure they are ready for the future."  

Precision OT notes that its QSFP-DD transceivers support the continued growth of network traffic while being backwards compatible with existing QSFP optics.  

The new modules are designed to help cable MSO and data center network operators keep pace with increasing bandwidth demands as they evolve beyond 100 Gbps. 

"For us, at Precision OT, it is about creating network solutions that grow over time and accommodate increased demand cost-effectively, with both flexibility and agility," concluded Precision OT's Page.
