Abstract:

We have developed the most compact 4 × 25 Gb/s ROSA (receiver optical sub-assembly) module and the most compact optical transceiver module for 100G Ethernet optical interface over up to 10km single mode fiber. They are compliant with CFP4 MSA and IEEE 802.3ba 100GBASE-LR4 standard. In order to reduce the size and simplify the manufacturing process of the 4 × 25 Gb/s ROSA module, we propose a butt-coupling structure between an optical demultiplexer and four PD chips. The optical transceiver has eye margins of more than 20%, and the receiver sensitivities of less than -11.5 dBm for four channels.

I. Introduction

100 Gigabit Ethernet was standardized by IEEE802.3ba in June 2010, and 4 × 25 Gb/s LWDM (Local area network Wavelength Division Multiplexing) method (100GBASE-LR4) was adopted as a standard for 10km single mode fiber transmission [1]. 100 Gigabit Ethernet optical signal is composed of four lanes with the rate of 25.78125 Gb/s, and the center wavelengths for each lane are assigned to 1295.56 nm (lane 0), 1300.05 nm (lane 1), 1304.58 nm (lane 2), 1309.14 nm (lane 3).
