CST Global, a wholly-owned subsidiary of Sivers IMA Holdings AB and the UK’s leading, independent, III-V opto-electronic, semiconductor foundry, has announced successful sampling of its 1270nm, 10Gb/s and 2.5Gb/s, Indium Phosphide (InP), DFB lasers for next generation, passive optical networks (NG-PON). The announcement comes ahead of the 2017 Broadband World Forum, Berlin.
According to research organization, Ovum, the number of gigabit broadband subscribers is expected to exceed 65 million by 2022. Broadband operators must rapidly evolve their access networks to meet this projected increase in consumer demand.
Broadband-to-the-home has most commonly been delivered via fiber, copper or cable infrastructures for last mile connections (LMC): the connection between the end-user and central exchange. CST Global’s NG-PON, DFB lasers will be used in the optical network units (ONUs) found at the user end of fiber-to-the-home broadband. Sivers IMA has previously announced its use of 60 GHz Fixed Wireless Access (FWA) for last mile connection as a multi-gigabit, wireless alternative to fiber. The Sivers IMA solution uses 802.11ad millimeter wave Wi-Fi technology, commonly known as WiGig. WiGig by-passes the last mile fixed infrastructure altogether, removing the need for any expensive civil works.
Sivers IMA and CST Global together offer the chip technologies necessary for multi-gigabit broadband-to-the-home for both wireless and fiber, last mile connections,” said Anders Storm, CEO at Sivers IMA. “I am very satisfied that we are able to deliver on this dual strategy, by offering chips for the two prevailing technologies in this growing market.
The CST Global asymmetric, 1270nm DFB lasers have been successfully beta sampled and deliver 10Gb/s download and 2.5Gb/s upload data speeds. The symmetric, 1270nm DFB lasers have been successfully alpha sampled and deliver 10Gb/s download and 10Gb/s upload data speeds.
