a Product specifications are subject to change. 
b Standard fiber length is 3 m, protective Teflon tubing length is 2.15 m in a 2 m armor cable jacket. Customers should contact EOT regarding other fiber requirements.
Unless otherwise specified by customer Insertion loss of light through fiber cladding is not included in the insertion loss specification.
Insertion loss of light through fiber cladding is not included in the insertion loss specification.
Case temperature ≤50 ºC

Note: It is recommended that the isolator be attached to the laser enclosure using a compression fitting that secures only the outer, metal reinforced jacket. The inner PTFE tube is meant as an abrasion barrier for the optical fiber and should be allowed to move freely with the fiber.
