OSFP Riding Heat Sink (OSFP-RHS) is a 9.5mm high pluggable module which does not have an integrated heat sink. In place of SFP’s integrated heat sink, OSFP-RHS cage shall have a riding heat sink. To prevent insertion of OSFP-RHS into a standard OSFP cage, the shape and location of the positive stop have been changed. […]
Q: What is Linear Pluggable Optics (LPO)? A: Linear Pluggable Optics refers to a solution that utilizes a low-power pluggable module that does not incorporate a DSP chip. The signal path from end to end in the link is considered linear, enabling lower power consumption through specialization. As with traditional pluggable modules with a DSP, […]
IP over DWDM (IPoDWDM) is a technology used in telecommunications networks to integrate IP routers and network switches in the OTN (Optical Transport Network). A true IPoDWDM solution is implemented only when the IP Routers and Switches support ITU-T G.709. In this way IP devices can monitor the optical path and implement the transport functionality […]
Starting in 2024, the demand for 800G is increasing, and soon in 2025 and 2026 1.6T will also delivered to the market. We shall explain the form factors of 800G and 1.6T modules. Based on the applications, there are Pluggable optical transceivers, Active optical cables, Active electrical cables, Active copper cables, and Direct-attached copper cables. […]
Since the very beginning of 2023, The demand for AI network interconnection products has been increasing. operators are familiar with Optical Transceivers, Active Optic Cable (AOC), and Direct Attach Cable (DAC). Is Active Electrical Cables (AEC) a good alternative solution to copper cables for AI networks? Currently, in the market, there are QSFP-DD and OSFP […]
LPO is short for Linear Pluggable Optics (or Linear-drive Pluggable Optics), it is a potential technology to satisfy the low power consumption and high bandwidth demand of data centers like CPO (Co-packaged Optics). Currently, IPEC (The International Photonics & Electronics Committee) is focusing on cutting-edge optoelectronic technologies. Image source from LightCounting The following are the […]

Q1: What is the difference among the terms “QSFP56”, “QSFP200”, “200G QSFP” and “200G QSFP56”? A1: They all refer to the same transceiver type. The electrical data path interface of a 200G QSFP consists of 4 lanes, with each lane transmitting 50Gbit/s data. Each lane of a 200G QSFP is designed to handle up to […]
Q1: What are the SFP-DD and DSFP form factors? A1: The SFP-DD is short for Small Form-factor Pluggable – Double-Density and SFP-DD form-factor is defined by the SFP-DD MSA, while the DSFP is short for Dual Small Form-factor Pluggable and is defined by the DSFP MSA. They are a compact SFP-like form factor with 2x […]
