The
Fibers adopted by our company are made by famous
factaries from abroad. The relevant technical specifications
comply with or exceeds the ITU-T G.652C recommendation.
1.Norms
Fiber complies with or exceeds the
ITU Recommendation G.652.C and the IEC 60793-2-50
type
B1.3
Optical Fiber Specification.
2.Products
Characteristics
>>Designed for operation
across the entire optical spectrum from
1260nm up to 1625nm,which
provides
50% more usable wavelengths and hence reduces
the cost of system.
>>Outstanding optical
performance supporting high-speed Transmission
technologies such as
DWDM and CWDM.
>>Being compatible with
existing 1310nm equipment.
>>DLPC8 or DLPC9 coating
offering good protection and excel lent
strip force stability.
>>Accurate geometrical
parameters that insure low splicing loss
and high splicing efficiency
.Splicing is fully compatible
with standard G.652 fibers that are available
on the market.
