SLS640 designed by Sino-Telecom is one of multifunction hand-hold light sources with high-quality, compact-size and 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.
