Optical Module
An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside world through a fiber optic cable. The form factor and electrical interface are often specified by an interested group using a multi-source agreement (MSA). Optical modules can either plug into a front panel socket or an on-board socket. Sometimes the optical module is replaced by an electrical interface module that implements either an active or passive electrical connection to the outside world. A large industry supports the manufacturing and use of optical modules. Electrical Interface Types There have been multiple variants of the electrical interface of optical modules that have been used over the years. Analog direct The earliest forms of optical modules had an analog Non-retu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multi-source Agreement
in the telecommunications industry, a multi-source agreement (MSA) is an agreement among multiple manufacturers to make products which are compatible across vendors, acting as de facto standards, establishing a competitive market for interoperable products. Products that adhere to multi-source agreements (MSAs) include: optical transceivers, such as the SFP, SFP+, XENPAK, QSFP, XFP The XFP (10 gigabit small form-factor pluggable) is a standard for transceivers for high-speed computer network and telecommunication links that use optical fiber. It was defined by an industry group in 2002, along with its interface to other e ..., CFP etc.; fiber optic cables; and other networking devices. MSAs strictly define the operating characteristics of these network devices so that system vendors may implement ports in their devices (e.g. Ethernet switches and routers) that allow MSA compliant devices produced by name brands, as well as third party vendors, to function properly.
