A method of making a biodegradable polymer composition including the steps of providing a first component being either one of a thermoplastic poly(hydroxy ester ether) or a synthetic, hydroxy-functional polymer and providing a second component being a natural polymer. The method includes the steps of mixing the first component and second component together to form a mixture, compounding the mixture, and pelletizing the compounded mixture to form pellets of a biodegradable polymer composition.

The female format connector of claim 14 wherein the second material is one of an oxide, a nitride, an oxy-nitride or a polymer. 20. The female format connector of claim 14 wherein the second material is silicon nitride. 21. The female format connector of claim 14 wherein the second material is silicon carbide. 22. The female format connector of claim 14 wherein the second material is a carbon based compound. 23. The female format connector of claim 22 wherein the carbon based compound is a diamond thin film. 24. A female format connector, usable for connection with a male format connector having at least one alignment pin, the female format connector comprising: a housing, a ferrule, contained within the housing, comprising at least one high-precision piece coupled to a low precision piece, wherein the low precision piece comprises a first alignment opening dimensioned to accept the alignment pin of the male format device; wherein, prior to being coupled to the low precision piece, the at least one high-precision piece comprises multiple fiber holes and a removable portion comprising at least part of a second alignment opening having a first shape, and wherein the first and second alignment openings are sized and positioned to provide accurate alignment between the high-precision piece and the low precision piece during coupling of the high-precision piece and the low precision piece to each other; and wherein the shape of the second alignment opening in the high-precision piece, after coupling, has been modified to a new shape. 25. A female format connector, usable for connection with a male format connector having at least one alignment pin, the female format connector comprising: a housing, a ferrule, contained within the housing, comprising at least one high-precision piece coupled to a low precision piece, wherein the low precision piece comprises a first alignment opening dimensioned to accept the alignment pin of the male format device; wherein, prior to being coupled to the low precision piece, the at least one high-precision piece comprises multiple fiber holes and a wall surface defining a second alignment opening, and wherein the first and second alignment openings are sized and positioned to provide accurate alignment between the high-precision piece and the low precision piece during coupling of the high-precision piece and the low precision piece to each other; and wherein, after coupling, a portion of the high precision piece used for alignment is removed. 26. The female format connector of claim 25 wherein the portion includes at least half of the second alignment opening. 27. The female format connector of claim 25 wherein the portion includes all of the second alignment opening. 28. The female format connector of claim 25 wherein the high precision piece has a first side and a second side and the portion consists of some of the wall surface. 29. A method of forming a female format ferrule comprising: coupling a high precision piece, having a first wall defining a first alignment hole, to a low precision piece, having a second alignment hole, the first and second alignment holes being sized to accept a common alignment pin for effecting an accurate alignment between the high precision piece and the low precision piece during the coupling; and following the coupling, removing at least some of the first wall.
