Optical module types include 1 × 9, SFF, SFP, GBIC, XENPAK, XFP, SFP+ and 10G optical modules above.

Since its inception in 2007 AOC come out, the market has been volatile. Service has always been the mainstream of high-performance computer market 4x10Gbps QSFP+ AOCs is the case. Thankfully, the data center servers using 10GbE SFP+ AOCs. Accounting for a quarter of $ 87 million in 2014 AOC market. Data centers also require higher speed Ethernet: 25G, 40G, 100G, or 400G. The connection between the needs of the core router chassis AOC. This makes the AOC market in 2020 grew to $ 193 million.

SFP+ Direct Attach Copper Cable is a copper interconnect using a passive twin-ax cable assembly that connects directly into an SFP+ housing. It has a range of 10 meters and like 10GBASE-CX4, is low power, low cost and low latency with the added advantage of having the small form factor of SFP+, and smaller, more flexible cabling.

Recently, Gigalight launched the second generation of the optical module tester 10G SFP+ Checker, integrated support up to 10G bit error rate testing, optical power test, read and write EEPROM, DDM monitor a variety of functions in one, with high precision, low power consumption, lightweight and easy to carry and so on. Suitable for flexible deployment scenarios site identification and checking work status and performance SFP+, which greatly helps integrators, engineering users streamline operations and reduce operating costs.

Including optical receiver module, optical transmitter module, optical transceiver module and optical transponder modules.

QSFP is from a simple single-mode fiber SONET applications out into other multimode fiber applications, such as Gbps Ethernet, Fibre Channel, InfiniBand and so on. Many MSA members of the supply VCSEL chip, parallel VCSEL chips, pushing the QSFP technology in the field of multi-mode.

Fiber optic transceivers may be in a response network traffic surge center of attention, but the link platform, panel-board equipment and other functions is the supplier of fiber optic transceivers can achieve product differentiation play space.

QSFP (Quad Small Form-factor Pluggable): Quad-SFP interfaces (QSFP), QSFP is to meet the market demand for higher-density, high-speed pluggable solutions born.

Many people do not know the difference between SFP and SFP+, so sometimes unnecessary trouble. 10G module has gone from 300Pin, XENPAK, X2, XFP development, and ultimately with the same size and SFP 10G transmission signal, which is the SFP+. SFP With its compact and low cost advantages to meet the equipment needs of high-density optical module, the standard introduced from 2002 to 2010 has replaced 10G XFP become the market mainstream.
