Muti-functional optical Light Source, optical transceiver

Muti-functional optical Light Source, optical transceiver
Product Detailed
1. SLS640 multifunction hand-hold light sources 2. high-quality 3. compact-size 4. convenient-operation.

SLS640 is engineered for the daily maintenance of the fiber communication networks. Cooperating with SPM power meter series, it is suitable for the insertion loss testing with large dynamic range for the fiber networks like PON, FTTH, OFS etc.

SLS640 provides 1310/1490/1550 built-in light source, which can be configured as continuous mode or modulated mode (270/1K/2KHz) according to user’s request. Additionally, a visible red light source (650nm) is optional for fiber trunk diagnostics in the on-field testing.


1.High stability of the output power2.One-button for wavelength switching3.Provide USB Management port which can download test data, revise thresholds and execute optical power calibration.4.Able to configure the automatic power-off or background lighting according to user's request.5.High-capacity Li battery with two recharging methods available (power adaptor, mini-USB connector)6.The instrument's ergonomic design fits comfortably7.Excel spreadsheet software provides quick and easy8.Interchangable adaptors cover FC, SC, ST styles9.The comprehensive user manual is easy to follow and will help you get started
