SFP modules for Ethernet over fiber
Small Form-Factor Pluggables (SFPs) are compact, standardised modular, hot-pluggable, optical or electrical transceivers for Gigabit Ethernet (1000Base-FX) or Fast Ethernet (100Base-FX).
Small Form-Factor Pluggables (SFPs) are compact, standardised modular, hot-pluggable, optical or electrical transceivers for Gigabit Ethernet (1000Base-FX) or Fast Ethernet (100Base-FX). The form factor and electrical interface are specified by a multisource agreement (MSA). Siqura XSNet™ SFPs are compliant with the MSA and intended to be compliant with all other equipment that is designed according this MSA.
The XSNet™ SFPs are available in a wide range of models for multimode or single-mode optical fiber, 100 Mb or 1000 Mb speed rate, various distances, and one or two fibers. There are also two electrical RJ-45 SFPs available (100 Mb or 1000 Mb speed rate). These are applied when an SFP slot must be connected to an electrical CAT5/6 cable.
The SFPs come in two speed grades: 100 Mb and 1000 Mb. Though the practice of using 1000 Mb SFPs in 100 Mb speed slots is fairly accepted - in most cases without problems - correct functioning cannot be guaranteed as the 1000 Mb SFP design is made primarily for 1000 Mb slots. Best practise is to use 100 Mb SFPs in 100 Mb slots. Even if a 1000 Mb SFP can run at 100 Mb, the combination of a 1000 Mb SFP (running at 100 Mb) and a 100 Mb SFP is NOT possible. The optical power windows (optical transmitter output power versus minimum optical receiver input) are totally different for 1000 Mb and 100 Mb SFPs.
The 100 Mb range of Siqura XSNet™ SFPs is optically compatible with the Siqura XSNet Media Converter range. With this variety of models, any network solution can be realized, while maintaining a competitive price level. XSNet SFPs are selected for use with many of Siqura’s SFP-ready series cameras, as well as XSNet™ series media converters and switches with SFP slots.
For high-capacity special applications, a range of CWDM SFPs is available on request. Contact your local sales representative for more information.
