A dozen cassette transceivers are hanging next to the bridge, and the power adapters are hanging on the floor. After the labels come off, no one can tell which one controls which channel. This is a common scene in computer room renovations. Box type and rack type are not divided into grades, but a division of labor determined by the number of links. This article explains this dividing line.
Advantages and upper limits of box type
The box-type monomer is flexible and can be replaced with another one if it breaks down. It is suitable for links with scattered points.Gigabit single mode single fiber one optical one electrical fiber optic transceiverThis type of model is a typical box-type device. However, as the number increases, three problems arise: the power adapter occupies the socket and is of varying quality, the equipment is scattered and cannot be inspected uniformly, and heat dissipation and dust prevention all depend on the on-site environment. Generally, if more than eight links are concentrated in a weak power room, the hidden cost of the box solution will begin to exceed the equipment itself; if the number of links will continue to grow, reserving rack space is much easier than reserving desktop space.
How to settle accounts for rack type
19 inches14-slot box transceiver rackThe idea is centralized power supply, unified instructions, and front-side cable management: one link corresponds to one slot, and if a board fails, it can be replaced with power without touching neighbors. Accounting is also simple: allocate slots according to the number of aggregation point links, and leave two to three spare slots for expansion, which is more cost-effective than installing additional racks in the future. In EB-LINK's solution, cassette and plug-in card devices can coexist in the rack, and the existing investment does not need to be scrapped.
Three details when landing
- After the rack is fixed into the cabinet, plan the wiring of the patch panel first, and leave enough bending radius for the optical fiber tray.
- It is recommended to use a UPS for the unified power supply of the rack to avoid batch disconnection caused by a single adapter failure.
- Slot labels and upstream port tables are updated simultaneously, eliminating one misunderstanding during handover.
