product description features applications performance specification ns s0048 - r11. (web) 20141113 ultra-mini 1x1, 1x2, 2x2 (add/drop) fiber-optic switch ofms sm series oplink ofms ultra-mini fber-optic switches are ideal for module and system integration where the unique unilateral input and output fber confguration is preferred. these switches are designed for use in re-confgurable optical add/drop multiplexers, optical cross-connect systems, and network switching for fault protection applications. the opto-mechanical ultra-mini switch can be directly mounted on printed circuit board (pcb) and ofer the same excellent performance characteristics of oplinks standard ofms series switch products. the ofms miniature switches are telcordia standards gr- 1221 and gr-1073 qualifed. oplink provides customized design to meet special control and applications. also, op - link ofers modular assemblies that integrate other components to form a full function module or subsystem. parameters min typ. max unit operating wavelength range ( op ) 1290 ~ 1330 and/or 1525 ~ 1610 nm insertion loss 1 1x1, 1x2 0.5 db 2x2ad 0.6 polarization dependent loss 0.07 db return loss 50 db channel cross-talk 55 db repeatability 0.02 db switching time 2 4 ms operating voltage 5 10% vdc driving current 3 latching 22 32 ma non-latching 31 46 coil resistance latching 202.5 10% non-latching 145 10% cycle rate 10 hz durability 10 millions cycle operating power handling 500 mw operating temperature (t op ) 0 70 c storage temperature -40 80 c humidity 4 <85% rh, or <90%rh for short term switch type latching or non-latching, single coil fiber type corning smf-28 250m fber fiber color coding red, black, clear and blue for port 1,2,3 and 4 in order package dimension 250m bare fiber 29.0 (l) x 10.5 (w) x 7.85 (h) mm 900m loose tube 38.5 (l) x 10.5 (w) x 7.85 (h) mm ? miniature size ? unilateral input/output fiber confguration ? bi-directional operation ? 1x1, 1x2 latching or non-latching confgurations ? wide operating wavelength range ? seam-seal package ? highly stable & reliable ? network switching ? re-confgurable optical add/drop multiplexers ? optical cross-connect systems ? network protection and restoration ? module and system integration ? instrumentation, testing and measurement notes: 1) excluding connectors; add 0.3 db within op and t op . 2) switching time is defned as the time interval between electrical trigger and 90% of stable optical output. 3) a >20ms dc pulse is recommended for latching type of switch. 4) short term is defned as less than 96 consecutive hours and less than a total of 15 days over a one year period.
