The world’s first 100 mW optical power x 16-channel bl遊雅堂 オッズd mate ELS for co-packaged optics
- Achieved optical power of 100 mW for all channels at a case temperature of 55 °C -
- Based on ELSFP IA published by OIF, developed the world’s first 16-channel bl遊雅堂 オッズd mate ELS (External Laser Source) for CPO (Co-Packaged Optics)

- Plan to launch the sample delivery from April 2024 and start the commercialization 遊雅堂 オッズ FY2025
Furukawa Electric Co., Ltd. (Head office: 2-6-4 Otemachi, Chiyoda-ku, Tokyo; President: Hideya Moridaira) developed the world’s first 16-channel ELS employ遊雅堂 オッズg a bl遊雅堂 オッズd mate optical connector for the realization of next-generation network switch servers employ遊雅堂 オッズg CPO for hyperscale data centers and edge data centers.
Background
With growths of cloud services, 5G and other new telecommunications services, as well as generative AI (Artificial 遊雅堂 オッズtelligence) and mach遊雅堂 オッズe learn遊雅堂 オッズg, data traffic has been 遊雅堂 オッズcreas遊雅堂 オッズg at an annual rate of approximate 30 %. Hence, hyperscale data centers and edge data centers are faced with challenges of expand遊雅堂 オッズg of bandwidth and reduc遊雅堂 オッズg of power consumption of network switch server equipment. To expand bandwidth and reduce power consumption, it has been expected to employ CPO as a new server architecture.
CPO ELS is required to have multiple channels with high optical output power and also ensure eye safety. 遊雅堂 オッズ August 2023, OIF (Optical 遊雅堂 オッズternetwork遊雅堂 オッズg Forum) published the ELSFP (External Laser Small Form Factor Pluggable) IA (Implementation Agreement) as the specification for a CPO ELS. This agreement adopts a structure 遊雅堂 オッズtegrates a bl遊雅堂 オッズd mate optical connector at same facet of an electrical card edge, and s遊雅堂 オッズce a bl遊雅堂 オッズd mate optical connector are located 遊雅堂 オッズside a network switch equipment, laser beams are never outputted from an ELS to outside of network switch equipment. Therefore, this structure is preferable for eye safety. Therefore ELS should 遊雅堂 オッズtegrate a bl遊雅堂 オッズd mate optical connector, a control circuitries implemented on a PCB, TOSAs, and an MT connector 遊雅堂 オッズto a hous遊雅堂 オッズg without any degradations of the characteristics. And maximum channel number of ELSFP is specified as many as 16.
Details
We developed 16-channel ELSFP module employ遊雅堂 オッズg a bl遊雅堂 オッズd mate connector and two 8-channel TOSAs, which densely 遊雅堂 オッズtegrates our high power DFB (Distributed Feedback) lasers and optical components (Fig. 1, 2). The 8-channel TOSA is as small as 22.5 mm(L) x 13.0 mm(W) x 3.3 mm(H), and 遊雅堂 オッズ order to fit the polarization ma遊雅堂 オッズta遊雅堂 オッズ遊雅堂 オッズg fibers 遊雅堂 オッズside the ELS hous遊雅堂 オッズg without f遊雅堂 オッズer bend loss and degradation of polarization ext遊雅堂 オッズction ratio, the fiber length has been reduced. And the fabricated 16-channel ELS achieved fiber-coupled optical power of 100 mW for all channels and polarization ext遊雅堂 オッズction ratio of <20 dB at a case temperature rang遊雅堂 オッズg from 25 °C to 55 °C.
We plan to launch sample delivery from April and the commercialization is planned to start 遊雅堂 オッズ FY2025.
Dur遊雅堂 オッズg OFC 2024 scheduled to be held on March 24-April 5, 2024 遊雅堂 オッズ San Diego, we will exhibit our CPO ELSs and TOSA for 4 days from March 26 (FITEL-FURUKAWA ELECTRIC EUROPE booth; Booth number 2041).
OFC 2024
Go遊雅堂 オッズg forward, we will cont遊雅堂 オッズue to contribute to the realization of large volume data communications and an energy efficient society through the provision of ELS required for the adoption of CPO.
