Source Photonics launches portfolio of optical transceivers to enable 5G ramp

Leveraging several years of high-speed optical transceiver development and high-volume shipments into wireless, data-center and routing applications, Source Photonics Inc of West Hills, CA, USA has launched a comprehensive 5G portfolio (including 25G, 50G and 100G products transmitting between 300m and 40km) serving front-haul, mid-haul and edge applications.

Bandwidth-hungry applications such as artificial intelligence (AI), virtual reality (VR) and augmented reality (AR), have increased front-haul requirements from 10Gb/s to 25Gb/s, notes the firm. The emergence of base-station pooling and eCPRI is driving mid-haul and back-haul bandwidth requirements beyond 50Gb/s while centralization and fiber constraints have increased the reliance on longer reach and WDM capabilities.

“Our broad portfolio of 25G/50G/100G optical transceivers supported by in-house high-volume manufacturing capability enable us to support the customers during their transition from 4G to 5G deployment,” says Supriyo Dey, senior director of product line management. “We have started volume shipment to a number of customers.”

The new portfolio of 5G transceivers includes:

25G SFP28 LR Lite supporting 25G CPRI/eCPRI and 25GE links up to 2km on duplex single-mode fiber;
25G SFP28 LR supporting 25G CPRI/eCPRI and 25GE links up to 10km on duplex single-mode fiber;
25G SFP28 20Km supporting 25G CPRI/eCPRI and 25GE links up to 20km on duplex single-mode fiber;
25G SFP28 BiDi supporting 25G CPRI/eCPRI and 25GE links up to 15km on simplex single-mode fiber;
25G SFP28 LAN-WDM 6 channels from 1287nm to 1309nm; supporting 25G CPRI/eCPRI and 25GE links up to 20km on duplex single-mode fiber;
50G QSFP28 LR supporting 50GE links up to 10km on duplex single-mode fiber;
50G QSFP28 ER supporting 50GE links up to 40km on duplex single-mode fiber; and
100G QSFP28 LR supporting 100GE links up to 10km on duplex single-mode fiber.

Source Photonics is giving a live demonstration of 50G QSFP28 ER over 40km fiber and 25G SFP28 LAN-WDM over 20km fiber in booth #4021 at the Optical Networking and Communication Conference & Exhibition (OFC 2019) in San Diego, CA, USA (5-7 March).
