Fiberdyne Labs debuts bend-insensitive assemblies

OCTOBER 31, 2006 -- Fiberdyne Labs has introduced the Tera Flow bend-insensitive assemblies.

OCTOBER 31, 2006 -- Fiberdyne Labs has introduced the Tera Flow bend-insensitive assemblies.

Higher-bandwidth optical networks are trending toward traffic in the L-band (1565 to 1625 nm) and signaling and testing in the 1625 nm to 1650nm range, says the company. Thus, fiber-optic assemblies need to meet new standards to ensure quality in DWDM, CWDM, SONET, and CATV applications. Fiberdyne says it has developed the TeraFlow bend-insensitive assemblies in response to this requirement. The assemblies are less susceptible to bend-induced losses in the C-band (1530-1565 nm) and L-band (1565-1625 nm).

Main features and benefits include:


  • Operation with a bend radius as small as 0.6 inches (15 mm). For comparison, the minimum bend radius of standard SMF-28e is 1.2 inches (32 mm).
  • Telcordia Specification GR-20-CORE Issue 2 specifies a limit of 0.5 dB of loss per 16-mm bend radius on C & L band Systems. The TeraFlow assemblies exceed this requirement, the company asserts.
  • TeraFlow - Bend Insensitive is designed to ensure optimal performance for applications using the L-Band or that may be upgraded in the future to the L-Band.
  • The assemblies are blue in color to identify them.

Many currently deployed singlemode installations cannot support DWDM implementations because of bend radius violations (especially at the fiber distribution points), Fiberdyne Labs asserts. The company is positioning TeraFlow - Bend Insensitive as an optimal upgrade alternative.
