Silicon photonics is the study and application of photonic systems which use silicon as an optical medium. The silicon is usually patterned with sub-micrometre precision, into microphotonic components. This technology is getting popular a few years ago, however, based on research from LC (LightCounting), the market demanding for SiPh will increase in the next couple […]
The Quad Small Form Factor Pluggable Double Density (QSFPDD) Multi-Source Agreement (MSA) group announces the release of a hardware specification revision 7.0 for updating QSFP-DD, The main topic is introducing QSFP-DD800 and QSFP112 form factor. QSFP-DD is the premier 8-lane data center pluggable module form factor. This QSFP-DD optical module designed backward compatible with existing […]
Cisco transceivers can be classified according to different standards. Depending on transmission rates, the transceivers are classified into 400G, 100G, 40G, 25G, 10G, 1G, and 100M transceivers. Depending on modes, the transceivers are classified into single-mode and multi-mode transceivers. Depending on encapsulation types, the transceivers are classified into: QSFP-DD, QSFP, CPAK, GBIC,CFP, CFP2, CXP, SFP28, […]
HUAWEI transceivers can be classified according to different standards. Depending on transmission rates, the transceivers are classified into 400G, 100GE, 40GE,25GE, 10GE, GE, and FE transceivers. Depending on modes, the transceivers are classified into single-mode and multimode transceivers. Depending on encapsulation types, the transceivers are classified into: SFP/eSFP, SFP+, XFP, SFP28, QSFP+, QSFP28, CFP/CFP2, CXP […]
The follow parameter introduction is focused on the performance of internal components packaged inside the transceiver, mainly the transmitter optical subassembly (TOSA) and the receiver optical subassembly (ROSA). Once a client’s line arrives at the TOSA, the signal is converted from electrical to optical. Then, the TOSA sends and transmits the information. In the opposite […]

Optical link budgets – Vary by ODN class and PON type. However, 29 dB is often used as a “loose” loss budget for both XGS-PON and NG-PON2 for Class N1/N2 applications. This reasonably healthy link budget can be adversely affected by bending losses at NG- PON downstream lambdas. Spectral losses – XGS-PON (1270 nm) upstream […]
