The SR series switches are manufactured for harsher environments, and are specified for a wide operating temperature range of -25 C to +65 C. Both single-mode (SM) and multimode (MM) versions of the SR Series switch connect optical channels by redirecting optical signals into a selected output fiber. This is achieved using a mirror driven by a highly precise mechanism that is activated via an electrical control signal. Switching can be done by applying either a direct electrical or TTL control. The SR series is available in both single-mode and multimode. Using collimating lenses minimizes the insertion loss (IL) and improves the repeatability and stability of the switch parameters. The SR Series is optically passive and is, therefore, transparent to signalling formats and bandwidth. All configurations are optimized for bidirectional performance. website : www.jdsu.com/test RUGGEDIZED SMALL CHANNEL COUNT SWITCH MODULE 2 SR Series Switch Configurations Quick Picks Specifications Parameter TypicalMaximum Insertion loss (IL) Single-mode1 (SM) 1 x 2 0.6 dB 0.9 dB SM 2 x 2 0.9 dB 1.2 dB Multimode1 (MM) 1 x 2 0.5 dB 0.8 dB MM 2 x 2 0.8 dB 1.1 dB Return loss (RL) SM2 (high RL) 60 dB 55 dB MM 25 dB 20 dB Polarization dependent loss (PDL)2 SM 0.06 dB 0.1 dB IL stability3 0.03 dB 0.05 dB Repeatability4 0.01 dB 0.02 dB Crosstalk SM -60 dB -50 dB MM -45 dB -35 dB Optical input power N/A 300 mW Switching time 7 ms 10 ms Control signal duration 25 ms N/A Cycle rate N/A 10 Hz Power 55 % V DC/50 mA (75 mA for TTL option) Control Direct or TTL Operating temperature N/A -25 to 65C Storage temperature N/A -40 to 80C Humidity (non-condensing) N/A 95% Dimensions (W x H x D) SR1 x 2, 2 x 2 70 x 17 x 40 mm Weight 90 g (110 g for Dual 2 x 2) 1.
