Model 922 Optical Transceivers

Web Product Page Image

SUBSEA QUALIFIED SFP MODULES

Model 922-SFP (Small Form-factor Pluggable) modules are rugged and proven optical transceivers for Focal’s Subsea Oilfield Communications (SOC) product line. These API/ISO qualified components are available in various optical wavelengths with 100 Mbps and 1000 Mbps data rates suitable for Ethernet links of up to 200 km on singlemode fiber. SFP variants include dual fiber configurations and bidirectional modules for operation over a single fiber. Qualified subsea optics may be used for passive optical redundancy or to optically combine multiple Ethernet links via CWDM (Coarse Wavelength Division Multiplexing) on a single fiber.

Focal’s 922-SFP modules are qualified and tested for use in permanent subsea installations, ensuring reliable operation over extended lifetimes. The availability of extensive design testing and qualification reports, plus Focal's experienced engineering staff, simplifies system level analysis, lowers operational costs, and reduces technical risks during all project phases.
