Questions & Answers
Q1: How many data channels can add or drop over fiber trunk?
A2: The passive OADM modules can add or drop 1, 2, 4, 8 data channels at any point along the trunk.
It can achieve bi-directional 1~8CH data add and drop with Double fiber.
Q2: What's the packing size for the OADM?
A3: This OADM may be used as a standalone tabletop device or mounted in 1-unit space of a 19" data rack.
Q3: What OADM can we have?
(1) CWDM single fiber single-sided, East or West
(2) CWDM Single Fiber dual-sided OADM, East and West
(3) Dual Fiber single-sided OADM 1U Rack, East or West
(4) CWDM Dual Fiber dual-sided OADM 1U 19inch Rack, East and West
