1260-88

Product catalog summary

Overview: The Racal Instruments™ 1260-88 series optical switch modules are designed for optical systems testing, leveraging the modular VXIbus architecture. These modules are ideal for SONET testing, fiber-optic component testing, and fiber network monitoring. They offer high repeatability and accuracy, with quick module replacement for maximum system uptime.

Specifications: The modules support single-mode fiber (9/125μm) with a wavelength range of 1290-1570nm. They feature low insertion loss (<1.2dB max, 0.6dB typical) and high isolation (>80dB min, 90dB typical). The modules are optically passive, independent of data rate, format, and signal direction.

Performance: The modules provide high repeatability (+/- 0.03dB sequential switching, +/- 0.010dB typical) and low polarization-dependent loss (0.05dB max). They include diffraction-limited collimating lenses for precise optical channel switching.

Interface and Environmental Data: Cooling requirements are 1.0 liters/second at 0.025mm H20. Power requirements vary by model, with +5VDC and +12VDC inputs. Operating temperature ranges from 0°C to 50°C, with storage from -20°C to 70°C. The modules are designed to withstand shock (30g, 11msec) and vibration (0.013” peak-to-peak, 5-55Hz).

Compliance and Safety: The modules comply with EN55011A emissions standards and IEC801-2, 3, 4 immunity standards. They meet EN61010-1 safety standards and carry the CE Mark for compliance with European electrical safety standards.

Mechanical and Ordering Information: The 1260-88A is a single-slot, C-size module, while the 1260-88B is a dual-slot, C-size module. Both use FC style front panel interface connectors. Ordering options include the 1260-88A-1 and 1260-88B-1 models, with additional user manuals available.

Catalog excerpts

RACAL INSTRUMENTS 1260-88A/B VXIbu Optical Switch Module High Repeatability for Accurate Testing Racal Instruments™ 1260-88 series optical switch modules bring the advantages of the modular VXIbus architecture to optical systems test. Modules can quickly and easily be removed and replaced for maximum system uptime. In addition, we offer overnight depot spares contracts to free you from stocking spares. Modular VXIbus Architecture These optical switch modules are ideal for SONET test, fiber-optic component test, and fiber network monitoring. Ideal for SONET Testing Quick Delivery from Stock Optional Overnight Depot Spares Special Configurations Readily Available The 1260-88A single 1 x 8 topology is used primarily for simple switching. The 1260-88B dual 1 x 8 topology can be used for simplex or duplex switching. The 1260 series “include” command permits simultaneous closure of both switches with a single software command, when a duplex scheme is required. Also, the 1260-88 modules feature diffraction-limited collimating lenses to achieve precise switching of optical channels. This implementation provides highly repeatable switch paths, facilitating the construction of highly accurate optical test systems. These switches are optically passive and operate independently of data rate, data format, and optical signal direction. The 1260 series line includes VXIplug&play support of Win95/NT frameworks including drivers for LabWindows/CVI and LabView. Please refer to the Option 01T data sheet for additional product features and specifications.
