As mentioned above, optical spectrum analyzers are often not particularly accurate for measurements of optical power. Some instruments, however, can be expected to have a reasonable calibration – in p.
The 4-core fiber termination box provides a stable, protective joint between optical cable and distribution pigtails at the end of fiber cables. It is typically used in cabling work area subsystems. The cable entry can accommodate 5. 0mm fiber cable and splice up to 4. 4 Port Fiber Termination Box is designed for FTTD (Fiber to the Desktop) system applications.
